Foramen Vesalius was present in 60% of total skulls studied. The foramen showed variations in incidence and shapes, while there was no statistically significant difference in the maximum dimension between foramen Vesalius on right and left side. There could be some developmental reasons to explain these variations. The findings of this study could be important to anatomists and also equally essential for clinicians who approach middle cranial cavity for various procedures.

Interest in the study of pulmonary veins and its ostia has considerably increased in recent times after the realization of the fact that atrial fibrillation may originate from the triggers in the pulmonary veins as they receive the extension of myocardial sleeves from left atrium. Researchers have found that the classic pattern of two ostia in the either side of the left atrium occurs in 70% of general population. The variations pulmonary venous drainage patterns are mostly congenital in origin and related to the complex development of venous system. AIM: The pulmonary venous ostia were studied with respect to their number and orientation. METHODS AND MATERIAL: The present study was carried out in the Department of Anatomy,

CONTEXT: Variations in the peritoneal reflections of the gallbladder are encountered during surgery and post-mortem examinations mainly form of mesentery and often have significant clinical implications, which can be life threatening at times. AIM: In this study, the manner of the peritoneal reflection over the gall bladder, its relative adherence to the gall bladder fossa and the relation of the fundus to the inferior margin of liver was examined. SETTINGS AND DESIGN: This cadaveric gross anatomical study was undertaken in the Department of Anatomy, Jawaharlal Nehru Medical College, Sawangi (Meghe), Wardha, Maharashtra, India and Subharti Medical College, Meerut, Uttar Pradesh, India, in the course a four year period i.e. 2008 to 2012, after obtaining necessary permission from the Institutional Ethical Committees. METHODS AND MATERIAL: It was carried out on one hundred gall bladders specimens, obtained from 10% formalin fixed cadavers during routine undergraduate students dissection The liver along with the gall bladder was retrieved from the abdominal cavity during undergraduate dissection of the abdomen and the peritoneal reflection over it was studied. RESULTS: Differential peritoneal reflections were observed in seven out of hundred specimens and formation of mesentery over the whole organ was found in two. In two there was mesentery over the neck and upper part of body. One the gall bladder was found floating in the gall bladder fossa but without the formation of mesentery. CONCLUSIONS: Differential peritoneal reflections of gall bladder were seen in seven specimens and mesentery formation to various degrees was seen in four. It was observed that peritoneal attachment of the gall bladder and the relative adherences of the viscus to the gall bladder fossa were closely associated.

Introduction: Being the chief flexor of the elbow joint, brachialis muscle, also known as ‘work horse’ of the elbow or Portal’s muscle is one of the three muscles of the front of arm. Ascertaining the morphology of the muscle is of considerable clinical significance because infrequent mention of the pathologies like tear, rupture, tendinopathies, etc., coupled with the conflicting reports of its morphology may often leads to inaccurate diagnosis of clinical conditions pertaining to it. Aim: To study the origin of the muscle in the form of number of heads and type of fibres at origin, site and manner of insertion, mode of nerve supply and presence of accessory slips. Materials and Methods: The study was carried out in the Department of Anatomy, Parul Institute of Medical Sciences and Research, Parul University, Vadodara on the 82 upper limbs used for routine dissection of first MBBS students. After incising the skin, superficial and deep fascia of the arm and cubital fossa, the biceps was retracted to visualise the origin, insertion and nerve supply of the brachialis muscle. Results: In all 82 (100%) arms, the muscle arose by lateral superficial and medial deep heads. Deep head inserted into the coronoid process and upper part of the ulnar tuberosity by an aponeurosis. In 81 (98.8%) specimens, superficial head was inserted by round tendon on to the ulnar tuberosity distal to the deep head. In one (1.2%) specimen, fibres of the superficial head were merging with biceps tendon and inserted on to the radial tuberosity. In 75 (91.5%) arms, muscle was supplied by musculocutaneous nerve and radial nerves and in four (5%) cases by the musculocutaneous, median and Radial Nerve (RN) whereas in 3 (3.5%) case by median and radial nerves. Accessory slips were present in four (5%) specimens. Conclusion: Considerable difference in the morphology of the brachialis was found with regards to the classical picture and should be kept in mind before undertaking any surgical procedure in the arm and elbow region.
