As many important nerves emerge from the posterior border of sternocleidomastoid (SCM), it is important to know the morphological anatomy of sternocleidomastoid for surgical as well as radiological purpose. During routine dissection of head and neck for student demonstration, an accessory head of sternocleidomastoid was found arising from the superior surface of the middle third of the clavicle on the right side of the neck. Sternocleidomastoid is a key landmark as it divides the neck into anterior and lateral regions (anterior and posterior triangles respectively. Morphological variations arise due to the complexity of sequential development of any region. SCM is an important surgical landmark for clinicians. A well versed knowledge of its variations can avoid diagnostic and surgical complications.

The seriousness of pancreatic diseases and the utmost importance of its correct diagnosis and treatment are expected to be helpful in correlating the functional capacity for further study in basic science and in decision making in clinical settings especially in transplant surgery of pancreas. Knowledge of normal morphometry of pancreas in living subjects is essential for understanding the segmental resection of pancreas as well as pancreatic imaging. A descriptive and cross-sectional study was conducted in the Department of Anatomy, Forensic Medicine & Pathology of Gauhati Medical College, Guwahati from May, 2016 to December 2019 on 103 specimens of human pancreas from 13 to 78 years age of both sexes. The collected samples were divided into seven age groups: A (10-19 years), B (20-29 years), C (30-39 years), D (40-49 years), E (50-59 years), F (60-69 years) and G (≥70 years), for convenient description. The differences between length of pancreas were statistically significant in A vs C, A vs D, A vs E, A vs F, A vs G, B vs C, B vs D, B vs E, B vs F and B vs G. The differences between weight of pancreas were statistically significant in A vs F, B vs C, B vs G, C vs D, C vs F, D vs F, E vs F, E vs G and F vs G. The present study is expected to standardize the morphology of pancreas in Assamese population.

INTRODUCTION: The testes are ovoid or walnut shaped bodies suspended in the scrotal region by the support of scrotal tissue including non striated dartos muscle and spermatic cord. MATERIALS AND METHODS: The study was conducted in the Department of Anatomy, Gauhati Medical College, Guwahati on the testis of human, pig, goat and albino rat. They were divided into four mammals group consisting of 6 to 9 animals in each group. RESULTS: Biometrical values were statistically analyzed and signicant differences of length, breadth, thickness and weight were noted. It was found that in all groups, the measurements were more in right side than the left but was found to be statistically insignicant. The highest values in case of length, breadth, thickness and weight were found in pig and lowest in the albino rat. This descending pattern of the biometrical value from pig to human and pig to albino rat to their body weight was highest in pig and lowest in albino rat. The high value in the right side is sup CONCLUSIONS: posed to be due to organogenesis in the right side where it occurs rst during the development. Therefore it needs further evaluation in this matter.

Background: Anatomical knowledge is an integral component of medical education. As there is little consensus over the best teaching methods, teachers may use a variety of teaching aids to help students understand a particular topic. Aims and Objectives: The aims and objectives of the study were to evaluate the impact of three-dimensional (3D) models as a teaching tool for the pelvis. Subjects and Methods: We conducted a study among 100 phase 1 MBBS students at a tertiary medical college to assess their level of understanding of pelvic anatomy from a teaching perspective. 3D models were constructed and used as teaching tools. Participants were evaluated using a Likert scale and knowledge-based tests, such as multiple-choice questions and identification questions. Results: The results showed that the teaching tool used significantly (P < 0.05) improved the understanding of the topic, and most of the students strongly agreed that the teaching was informative (71.4%) and interesting (73.7%). A total of 76.4% of students agreed that they could easily take notes. All students (100%) agreed that the teaching tool used was clear, audible, understandable, well organized, advancing their understanding of the subject, and helpful for revision and memory retention. Conclusions: The results suggest that using physical 3D models as a teaching tool improve the overall understanding of the pelvic region. However, further studies are required to assess the long-term impact of the 3D model as a teaching tool.
