Abstract
During routine dissection for first MBBS students on a 65 year old donated embalmed male cadaver in the Department of Anatomy at Grant Medical College & Sir J. J. Group of Hospitals, Byculla, Mumbai, we observed a variant head of the coracobrachialis muscle in the left arm. It originated from the middle part of the medial border of the shaft of the humerus and ran downwards and medially in front of the median nerve and brachial artery. It was inserted on the anteromedial aspect of the medial epicondyle of the humerus. The length of the variant head of the coracobrachialis muscle was 15 cm and the diameter was 0.2 cm. The photographs were taken for proper documentation. The branching pattern of the axillary and brachial arteries were normal. The variation was unilateral. The right upper limb was normal. The existence of accessory head of the coracobrachialis muscle should be kept in mind by surgeons operating on patients with high median nerve palsy and brachial artery compression and radiologists while doing scans of the arm.
