whole body donors. The prevalent reason for willingness were: to aid medical (75%) and anatomical education (54.9%) in the community and students cohorts, respectively. The prevalent reason for unwillingness to donate were: cultural reasons (25%) and religious beliefs (28%) in the community and student cohorts, respectively. Conclusion: In conclusion, the findings reflected that willingness to become whole body donors is low in this Black African South African population. The lack of willingness to become whole body donors was attributed to cultural and religious beliefs.

artery. Ulnar artery in lower part of arm gave superior ulnar collateral artery 6.5 cm above the elbow joint. Inferior ulnar collateral artery was absent. In the cubital fossa ulnar artery divided into a main trunk, a muscular branch and a common interosseous artery. Variations in the branching pattern of the arteries of upper limb have been described by various authors with a incidence of 1125% in various populations of world with equal preponderance in both sexes. The upper limb arterial system develops from lateral branch of seventh intersegmental artery which forms the axis artery. This terminates in the capillary plexus at the tip of limb bud. The proximal part of axis artery forms Axillary and Brachial artery. Radial and Ulnar artery develop later as sprouts of the axis artery close to the elbow. Any chemical or other factors disturbing the hemodynamic milieu result in origin to anomalous vascular pattern. These variable patterns are important clinically and should be reported.

S.D. Oraon ∗ , K. Sandhya Rajendra Institute of Medical Sciences, Ranchi, India Aims &objectives: The study of osteometric parameters may be helpful for forensic experts. Material &methods: 36 adult femur were taken with known sex for the study. By osteometric Board and vernier callipe. Anterioposterior diameter of shaft at upper, middle and lower segment and length was taken. Results: Mean antero-posterior diameter of shaft at upper segment was 23.26 mm, middle segment was 24.12 mm and lower segment was 24.86 mm and mean length of femur was 42.32 cm. Discussion: My findings were relevant with the findings of Kamdi et al. Conclusion: The knowledge of morphometric values is helpful to anthropological and forensic experts.

Sharma, M. Sharma Government Medical College and Hospital, Chandigarh, India Introduction: Variation in branching pattern of arteries of upper limb has diagnostic and interventional significance. Present case of variation in the branching pattern of arteries of left arm and forearm was observed during routine dissection of an adult male cadaver. The findings were photographed. Case Report: In present case brachial artery gave two branches in place of profunda brachii which ran in spiral groove. Distal to these branches, the brachial artery divided into radial and ulnar

Gaikwad Assistant Professor, Department of Anatomy, AIIMS Bhubaneswar, Odisha, India Introduction: Musculocutaneous Nerve is the nerve of anterior compartment of the arm and it arises from lateral cord of brachial plexus (C5-C7). It pierces coracobrachialis and descends laterally between biceps & brachialis to the lateral side of the arm. Just below the elbow it pierces the deep fascia lateral to the tendon of biceps and continues as lateral cutaneous nerve of the forearm. It supplies coracobrachialis, both heads of biceps and most of brachialis. Materials and Methods: During routine undergraduate dissection class the pectoral region, axilla and front of the arm was dissected. The specimen was cleaned and washed with water. An variation in the origin of musculocutaneous nerve was observed in left arm of a male cadaver. Observation: In the present case musculocutaneous nerve was not arising from Lateral cord of brachial plexus. Lateral cord of brachial plexus continued as lateral root of median. Two branches arose from the left median nerve that represented the musculocutaneous nerve and supplied the muscle of the anterior compartment of the arm. Conclusion: Variations in the origin of musculocutaneous nerve are not uncommon. Such variations should be kept in mind during surgeries of axilla, upper arm and in anaesthetic blocks.
