High mortality and morbidity are anticipated for the surgical procedures when undertaken without in-depth anatomical knowledge. With so much clinical importance in this area, our study will present a thorough understanding in terms of skull and CT values.The main aim of this study is to give the morphometric details of occipital condyles and foramenmagnum in cadaveric skulls andCT scans.Seventy dried human skulls and 70 CT images on the three-dimensional volume-rendered reconstruction of the skull base was used for this study.The length and width of the occipital condyle of right and the left side was 22.21 ±5.20 mm; 22.05±4.83 mm; 12.57 ± 2.50 and 12.68 ± 2.92mm respectively in cadaver skull. The length and width of occipital condyles in CT scans for right and left side was 21.61± 3.09 mm; 21.58± 3.50 mm; 13.04± 1.58 mm and 13.13± 2.54 mm respectively. The Anteroposterior and ...

Although it is usually a branch of the internal iliac artery, it may also originate from the external iliac system. This study was aimed at studying the variations of the OBA in its origin, the gender and the side differences in South Indian population. Relation of the OBA of external iliac origin to the femoral ring was also noted in view of its clinical significance. The study was done on 116 pelvic halves obtained from 58 cadavers. The OBA revealed considerable variations in its origin, course and relation to the femoral ring. It took origin from the external iliac artery and its branch, the inferior epigastric artery in 39.7%, inclusive of its dual origin from the external and internal iliac systems. Bilateral origin of the OBA from the external iliac system was noted in 22.4%. It was found to be placed lateral to the femoral ring in 78.2% and it was medial in 21.7% of the s...

The usage of flipped classroom (FCR) in medical education has always been rewarding. This study was to evaluate the effectiveness of FCR as a teaching method in comparison with traditional lectures in histology sessions in Sri Ramaswamy Memorial (SRM) Medical College Hospital and Research Centre, Chennai, Tamil Nadu, India. MATERIALS AND METHODS: This interventional study was conducted among the 1st year MBBS students in SRM Medical College Hospital and Research Centre for a period of 1 year (2018–2019 academic year). The histology sessions were taught using both traditional lectures and FCR methodology. Pre- and posttests were conducted for each traditional and FCR session with ten multiple-choice questions pertai...

Because these variations are usually associated with unusual femoral nerve formation, here we report a case of variation in the iliacus muscle combined with variation in the femoral nerve. Case report Variation in the iliacus muscle combined with variation in the femoral nerve was observed while performing a routine dissection of a 65-year-old male cadaver in the Department of Anatomy, SRM Medical College. The accessory iliacus muscle originated from iliac crest and inserted to the lesser trochanter of femur along with psoas major. This muscle variant was found to split the femoral nerve into medial and lateral slips. Conclusion The existence of this muscle variation along with nerve variation may increase the chances of nerve compression. Hence, detailed knowledge of these variations has immense importance in various pelvic and pelvifemoral surgeries.

These variations can occur from the gallbladder, cystic duct, hepatic ducts, common bile duct. Most of these variations are due to aberrations in the normal embryological development. Materials and Methods: The study was carried out in 25 foetal specimens of 7 to 9 months gestational age collected from the obstetrics and gynaecology department, Madras medical college, Chennai. Gallbladder was identified and dissection was carried out from the neck of gallbladder. Cystic duct, right hepatic duct, left hepatic duct, common hepatic duct and common bile duct were traced out. The relation of hepatic artery to the duct system was also noted. Result: This study reports an unusual variation in a foetal specimen out of 25 foetal specimens studied by dissection. In one of the specimen the common bile duct was absent. A small common hepatic duct from the liver entered directly i...

Anatomical knowledge of the cystic duct, common hepatic duct, com-mon bile duct and the surrounding vessels is necessary to avoid iatrogenic ductal injuries and inadvertent complications during biliary surgery. This study reports the presence of duplicated cystic duct in a fifty-year old male cadaver. The gallbladder in this case was sin-gle and not duplicated. The additional cystic duct was observed to arise from the neck of the gallbladder just above and parallel to the nor-mal cystic duct .It terminated into the main cystic duct itself. The normal cystic duct also originated from the neck of gall bladder and descended down and joined with the common hepatic duct to form the common bile duct. The ves-sels related to this biliary ductal system name-ly the proper hepatic artery and the portal vein were found to be situated normally within the hepatoduodenal ligament.

The artery has many parietal and visceral branches and hence the variations are frequently noted. The larger branches, namely, the inferior gluteal artery, the superior gluteal artery, and the internal pudendal artery, show sufficient regularity in their patterns of origin to allow typing. The variability of the IIA and its branching pattern were studied by dissecting sixty-eight male pelvic halves (34 right and 34 left) and forty-eight female pelvic halves (24 right and 24 left sides). In significant number of specimens, IIA terminated without dividing into 2 trunks as against the usual description. There was also considerable interchange of branches between the 2 terminal divisions. The patterns of branching noted were grouped as per Adachi’s classification. The incidence was noted to be as follows: type Ia in 60.6%, type Ib in 2.6%, type IIa in 15.8%, and type...
