Superior thyroid artery forms an important collateral circulation in case of unilateral occlusion of common carotid artery. Due to the close relation with superior thyroid artery, external laryngeal nerve is prone to injury during thyroid surgery. Superior thyroid artery occasionally arises from the bifurcation of common carotid artery or from the common carotid artery. In the present cadaveric case, during the routine neck dissection of the cadaver in department of anatomy, anomalous origin of the left superior thyroid artery was found. It was originating from the left common carotid artery at a distance of 1.8 cm proximal to the bifurcation of common carotid artery. The length of left superior thyroid artery was 3.2 cm. left Inferior thyroid artery was present and no anomaly was found. Right superior and inferior thyroid arteries were present and no variations were found. Knowledge about these variations in the origin of superior thyroid artery is extremely important in head and neck surgeries to prevent inadvertant injury and avoid torrential bleeding.</p> Balaiya Anitha, Shanthini Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/987 Sun, 06 Oct 2019 00:00:00 +0000 Anatomical and Morphological Study of Nutrient Foramen in Leg Bones http://aijournals.com/index.php/aanat/article/view/988 <p><strong>Introduction: </strong>Knowledge of position of nutrient foramina of long bones can be useful in certain surgical procedures. Bone ossification, growth and healing depend on its vascularity. Nutrient artery is the main source of blood supply of bone along with periosteal arteries. The topographical knowledge of these foramina is useful in certain operative procedures, in orthopedics as well as in plastic and reconstructive surgeries.AIM: The present study aims to determine the number and position of nutrient foramen of tibia and fibula and to observe direction and obliquity of nutrient foramina. <strong>Subjects and Methods</strong>: 100 adult dry bones including 50 tibia and 50 fibula were studied. Nutrient foramina were identified with naked eyes. The obliquity was determined with hypodermic needle. The nutrient foramina location was determined by dividing total bone into segments, the locations were validated by calculating foraminal index. <strong>Results: </strong>It has been observed that 98% (49) tibia has single nutrient foramina, double nutrient foramiana present in 2%of tibia. Most of the nutrient foramina in tibia are present in upper third i.e 65%(33).Foramina index of tibia is 45.05 with standard deviation of 8.29.In fibula single foramen&nbsp; was observed in 46(92%) and double foramina 2(4) and there is no nutrient foramen in 2(4). In 2 fibulae having double nutrient foramen, proximal foramen was directed downward and distal foramen was directed upwards. In 50%(25) nutrient foramina is present in posterior surface,most of nutrient are in middle third 48(96%).mean foraminal index of fibula is 45.05 with standard deviation&nbsp; of 8.29. <strong>Conclusion: </strong>Our study has attempted to put together findings from different studies regarding the number and position&nbsp; and obliquity of nutrient foramina of leg bones .The present study will be useful for orthopedic surgeons during procedures like bone grafting and more recently microsurgical vascularised bone transplantation and new graduates to understand the importance of nutrient foramina of long bones.</p> Donapudi Anusha, D.

Estimation of stature from bones is important for forensic as well as anthropological studies. It is necessary to derive the regression equations from the fragments of femur for medico legal situations. Thus from lower end of femur, estimation of total femoral length can be calculated and then this can be used to get stature by deriving statural formulae. In this study, regression equation for the estimation of total femoral length from epicondylar breadth of femur was computed. &nbsp;<strong>Subjects and Methods</strong>: Total 208 normal dry human femur bones which were preserved in antomy department of different medical colleges of Gujarat were studied. Total Femoral Length and Epicondylar Breadth of the Femur bone were measured for this study. <strong>Results: </strong>Epicondylar Breadth of femur displayed the higher correlation (0.828) with Total Femoral Length (TFL) for an individual measurement. As per regression analysis, regression equation is derived which is, B=338.004 + A * 1.390, Where A=Epicondylar Breadth of femur, and B= Total Femoral Length. Then the stature can be estimated by this total Femoral Length by the regression equations or the multiplication factors which are already established by various studies. <strong>Conclusion: </strong>The total Femoral Length can be estimated from fragmentary lower end of the femur. The total femoral length can be estimated by the equation presented in this study even in the absence of intact femur bone, and by which the stature can be estimated in sex and population sample.</p> Rakesh K.

The size of the pinna has been measured by some workers for designing hearing aids. No available literature on the study of correlation between the height of an individual and the size of pinna in different age and ethnic groups were available. In this study the height &nbsp;&nbsp;of the individual along with age &nbsp;and size of the pinna was measured in order to find out possible correlation in adult North Indian population. It was anticipated that a possible correlation could help in identification of different ethnic groups. <strong>Subjects and Methods</strong>: A study was conducted on 167 subjects including both males and females. The height of the individual was measured with the help of an anthropometric rod. The measurements related to total ear length &amp; ear width and lobule length &amp; width were taken with a digital Vernier Caliper&amp;the height of the individual was measured using stadiometer&amp; transparent graduated ruler. The pearson correlation were used to establish relationship. The data was analysed using SPSS version &amp; p&lt;0.05 was significant. <strong>Results: </strong>There was no difference between the size of the right and left pinna. The length of the pinna was 62.45±4.21 to 62.35±4.12mm and the width was 24.59±2.41 to 24.63±2.41mm. The length of the lobule varied between to 19.21±2.75 to 19.19±2.75mm and the lobule width was 20.14±2.54 to 20.10±2.56mm of both right and left pinna.In present study &nbsp;there was a &nbsp;significant correlation between rt ear length &amp; width with the height of the individual.Similarly Rt lobule length, Lt lobule length &amp; width &nbsp;also has significant correlation with height of individual. <strong>Conclusion: </strong>The present study reveals that the ear morphometry is an additional tool in prediction height from linear ear dimensions.</p> Vidit Dixit, Pratishtha Potdar, Jagmohan Singh Dhakar Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/996 Sun, 06 Oct 2019 00:00:00 +0000 Comparing the Effectiveness of Case Based Learning with Conventional Teaching in Anatomy http://aijournals.com/index.php/aanat/article/view/998 <p><strong>Introduction: </strong>Case based learning (CBL ) is an efficient method of making dry subject like anatomy interesting and student centered. <strong>Subjects and Methods</strong>: A group of students of 1<sup>st</sup> MBBs were taught by CBL while the other group was taught by conventional teaching methods and both the groups were assessed for their performance. <strong>Results: </strong>Students had a better understanding of the topic on being taught by CBL. <strong>Conclusion: </strong>CBL is a good approach to teach anatomy to medical students as it makes the subject quite lively and clinically oriented.</p> Shema K Nair, Neha Rai Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/998 Sun, 06 Oct 2019 00:00:00 +0000 Pattern of Smokeless Tobacco Use in Various Age Groups and Its Association withthe Frequency of Micronuclei in Exfoliated Buccal Cells http://aijournals.com/index.php/aanat/article/view/999 <p><strong>Introduction: </strong>Exfoliated buccal epithelial cells serve as an ideal site for an assessment of genotoxic events. Exfoliative cytology is economical and minimally invasive, its specificity and sensitivity of over 95% makes it an ideal diagnostic tool for mass screening purposes. An assessment of micronuclei in buccal epithelial cells gives a fair idea about the genotoxic events occurring in the oral cavity. <strong>Subjects and Methods</strong>: A case controlled study was performed on 300 participants. The participants were divided into four broad categories according to their pattern of consumption of smokeless tobacco. Thereafter they were subdivided in to various age groups. The distribution was done equally with 60 participants in each broad category. <strong>Results: </strong>The results in our study show that young adults consume the packaged form of smokeless tobacco while adults above 50 consumed tobacco leaves. Oral lesions were more common in young adults. Cellular alterations in the form of micronuclei were observed to have progressively increased from the control group to tobacco to gutkha users and the frequency of micronuclei was found to be highest in the oral lesions group. <strong>Conclusion: </strong>Certain lifestyle factors, such as consumption of smokeless tobacco are one of the major factors causing oral lesions. Frequency of micronuclei was assessed in exfoliated buccal epithelial cells. Maximum number of micronuclei was found in the oral lesion group. The age group with maximum cellular alterations was between 30-40 years. Hence we conclude that an assessment of micronuclei can be used as a biomarker for mass screening purposes since it is economical and a non- invasive procedure.</p> Sonia Jaiswal, PK Sharma Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/999 Sun, 06 Oct 2019 00:00:00 +0000 Morphometry of Human Placenta in Natural Conception and Assisted Reproduction with its Clinical Significance http://aijournals.com/index.php/aanat/article/view/1061 <p><strong>Introduction:</strong>Placenta is a mirror which reflects the antepartum status of fetus in utero. Our present study aimed to analyse the morphometry of placenta in normal and assisted reproduction.<strong>Subjects and Methods</strong>:30 Placentas of natural conception and 42 placentas of assisted reproduction (18 cases of singleton pregnancies, 12 cases of twin pregnancies) were collected from OG department, Rajah Muthiah Medical College and from private fertility centre in and around Chidambaram immediately after delivery. Morphometric dimensions of placenta like thickness, diameter, area, number of cotyledons were measured placental weight, fetal weight were also measured.<strong>Results:</strong>Placental weight of natural conception was 489 ± 107.84 grams, 316.78 ± 88.24 grams in assisted reproduction. Thickness of placenta was 2.767 ± 0.68 cm in natural conception, 1.78 ± 0.68 cm in assisted reproduction. Number of cotyledons, fetal weight, feto - placental ratio were also reduced in assisted reproduction.<strong>Conclusion:</strong>This is the first study to analyse the morphometric dimensions of placenta in natural conception and in assisted reproduction. Overall there was a reduction in all dimensions of placenta in assisted reproduction. This will be useful for pediatricians who handle the newborns of assisted reproduction.</p> Ananthi V, Rajkumar D, Muniappan V Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/1061 Fri, 01 Nov 2019 00:00:00 +0000 Gross Anatomical Study onthe Skull and Mandible ofthe Wild Boar (SusScrofa) In the Caribbean http://aijournals.com/index.php/aanat/article/view/1062 <p><strong>Introduction:</strong>Wild pigs (Susscrofa), which are found throughout the Caribbean island of Trinidad and Tobago, are sometimes used experimentally, in the field of biomedical science, to model the human anatomy.

During the procedures arterial catheterization damage to PFA may invite unnecessary and unpredicted complications. Precise anatomy of PFA forms strong foundation to minimize problems. The aims of the present study were to compare the right side and left side origin of profunda femoris artery cross sectional area, and to compare the distance of origin of the femoral artery branches from mid-inguinal point. <strong>Subjects and Methods</strong>: The study was conducted in Mata Gujri Memorial Medical College, Kishanganj, Bihar. This study based on dissections performed on 60 properly embalmed human cadaver specimens. All the mode of origin and its level calculated using statistically parameters and equations. The specimens with range between 21-60 mm in diameter were included for the study in left and right side origin level of PFA identified. <strong>Results: </strong>In the present study out of 60 a total 56 specimens screened for dissected lower limb specimens. The 52 had arising separately from femoral artery, 3 specimens arising as a common trunk with medial circumflex femoral artery, and 1 patient arising s common trunk lateral. Higher level of level of origin of PFA was found to be quite recurrently. The different type of range were observed in lateral circumflex femoral arteries and medial circumflex femoral arteries from right and left sides of arteries. The range between 21-30 mm diameters were successfully noted after the dissection in both the circumflex femoral arteries in right and left side. <strong>Conclusion: </strong>Range of origin of PFA was different in other cases and similar in some cases. Feature understanding regarding variations in point of branches, origin of PFA is clinically shown significance and should not be ignored. And the current observation will help to surgeons for the better understanding of variation and anatomical features of PFA.</p> Shambhu Nath Jha, Saif Omar Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/1123 Sun, 08 Dec 2019 00:00:00 +0000 Histological Structure of Meniscus http://aijournals.com/index.php/aanat/article/view/1124 <p>Meniscal damage is a common cause of joint injury, which can lead to the development of post-traumatic osteoarthritis, a prevalent form of osteoarthritis among the younger population Therefore, understanding the structural knowledge of the Meniscus will help in reproduce the native meniscus.

Third head was present in 16.6% and fourth head in 1.7%. The variation was unilateral in 72.7% and bilateral in 27.3% cadavers. Out of 120 limbs, 14 had additional head, and 71.4% of these were left-sided. In 73.3%, additional head joined with tendon and with the belly of BB in 26.7%. Three types of origin: anterolateral, posteromedial and high humeral were observed in 60%, 26.7% and 13.3%, respectively. The additional muscle was 11.7 ± 3.9 cm in length. The mean length on the right and left sides was 9.8 ± 3.3 cm and 12.4 ± 3.9 cm, respectively. Incidence of concurrent additional head and musculocutaneous variations was 42.8%. The nerve variations were unilateral with 80% on the left, and ipsilateral to additional muscle. <strong>Conclusion: </strong>The incidence of additional head in biceps brachii is 18.3% in the Indian population. Most common presentation is of a left-sided third head, and musculocutaneous variants occur on the same side as additional muscle. Presence of extra head should be considered during the analysis of the diagnostic scans, and awareness of the associated musculocutaneous nerve variations would be helpful in avoiding complications during surgical interventions.</p> Suman Verma, Sulochana Sakthivel Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/1185 Wed, 25 Dec 2019 00:00:00 +0000 A Study of Ponticulus Posterior of Atlas: Incidence and Clinical Co-Relations http://aijournals.com/index.php/aanat/article/view/1186 <p><strong>Introduction:</strong>The posterior ponticulus or foramen arcuale is caused due to ossification of the connective tissue around the vertebral artery (VA). Formation of a complete foramen may disturb normal functioning of VA. Aims and Objectives: The study was done to investigate the incidence of ponticulus posterior in dry atlas vertebrae.<strong>Subjects and Methods</strong>:50 dry human atlas vertebrae were examined from the bone collections in Dr RML Institute of Medical Sciences, Era’s Lucknow medical college and Saraswati Dental College, Lucknow. The presence of ponticulus posterior was looked for and documented with photographs.<strong>Results:</strong>The presence of this accessory foramen on the dorsal arch was the only anomaly found in these vertebrae. The study showed the presence of a unilateral foramen in two vertebrae and one vertebra showed the anomaly bilaterally out of these one was a completely occluded ponticulus with an incidence of 6%.<strong>Conclusion:</strong>The study provides evidence about the incidence of ponticulus posterior in the North Indian population. The clinicians should be aware of the possibility of this foramen in patients complaining of headache, vertigo and vertebrobasiliar insufficiency.</p> Navbir Pasricha, Eti Sthapak, Rajan Bhatnagar Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/1186 Wed, 25 Dec 2019 00:00:00 +0000 Histoarchitectural Study of Corpus Luteumin Pregnant and Non-Pregnant State http://aijournals.com/index.php/aanat/article/view/1187 <p><strong>Introduction:</strong> The fate and the life span of the corpus luteum depends upon whether fertilization occurs or not.

The infraorbital nerve needs to be blocked to anaesthetise lower eyelid, lateral nose, upper lip, upper teeth and gingivae for various dental treatments or maxillofacial surgical procedures. The present study was undertaken to determine the size and location of the infraorbital foramen in Telanagana population. <strong>Subjects and Methods</strong>: The study was conducted on 52 skulls. The size was determined by taking maximum vertical and maximum transverse diameters. The location of the infraorbital foramen was determined by measuring the distance between the centre of the foramen and infraorbital margin, the distance from the centre of the foramen to piriform aperture, and the distance from the centre of the foramen to anterior nasal spine. <strong>Results: </strong>The mean vertical and transverse diameter of the infraorbital foramen was 3.57 mm and 2.88 mm on the right side and 3.18 mm and 2.98 mm on the left side respectively. The mean distance from the centre of the infraorbital foramen to infraorbital margin, anterior nasal spine and piriform aperture was 7.31mm, 32.46 mm and 16.57 mm on the right side and 7.27 mm, 31.70 mm and 16.13 mm on the left side respectively. &nbsp;<strong>Conclusion: </strong>Knowledge about the exact size and location of the infraorbital foramen will be useful for the dental and maxillofacial surgeons to blocking the infraorbital nerve and also while performing various therapeutic procedures in this region.</p> Masooma Begum, B H Shiny Vinila Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/1240 Tue, 31 Dec 2019 00:00:00 +0000 Surgical Implications of Variations and Location of Plantar Arterial Arch: An Anatomical Study http://aijournals.com/index.php/aanat/article/view/1241 <p><strong>Introduction: </strong>The integrity of various structures of foot is mainly depends on its vascular supply. The foot is supplied by deep plantar arterial arch formed by deep branch of dorsalispedis artery and lateral plantar artery. So,the detailed knowledge of plantar arterial arch is necessary for advances in surgical reconstruction of foot, which in turn avoids the need for amputation. <strong>Subjects and Methods</strong>: 40 human feet procured from 20 embalmed cadavers of MVJ Medical College and Research Hospital, Bangalore used for the study. Dissection of foot was carried out and variations in the formation and&nbsp;&nbsp; branching pattern of arch are studied in detail.&nbsp; The results were tabulated and analysed statistically. To measure the topographical location of arch, first the length of foot was measured from tip of second toe and posterior most part of heel using flexible ruler. Depending on the length the foot is divided into 3 equal parts- Anterior, Middle and posterior parts. To know the exact location,the middle part is again divided into three equal parts- anterior middle(AM),intermediate middle (IM), posterior middle (PM). Zone in which arch located was noted down and percentage of each location is calculated. <strong>Results: </strong>The arches were classified into 6 types&nbsp; as per Adachi’s classification.TypeB-10%,Type C-32.5%,Type D-27.5%,Type E-17.5%,Type F-12.5%.Type A was absent. In the present study majority of arches were located in the anterior middle portion of foot. <strong>Conclusion: </strong>The present study will be of great help for reconstructive surgeons, microvascular surgeons and radiologist in the successful outcome of any reconstructive and vascular surgeries.</p> Varalakshmi KL, Khzier Hussain Afroze M, Sangeeta M Copyright (c) 2019 Academia Anatomica International http://aijournals.com/index.php/aanat/article/view/1241 Tue, 31 Dec 2019 00:00:00 +0000 Gender Difference in the Left Coronary Artery: An Angiographic Study. http://aijournals.com/index.php/aanat/article/view/1245 <p><strong>Introduction:</strong>The prevalence of coronary artery disease in India has led to a rapid transition in health status. Knowledge of coronary artery anatomy including anomalies and variations according to region is very important for clinical therapeutic surgeries.
