Abstract
Coracobrachialis muscle is a muscle of the arm and is known to show several variations in its attachments. During routine dissections, we found an accessory coracobrachialis muscle. It took origin from coracoid process of scapula and got inserted to the medial intermuscular septum and medial epicondyle of the humerus. It crossed the median nerve and brachial artery in the middle of the arm. This accessory muscle can be used in muscle transplants. Since it crosses the median nerve and brachial artery in the arm, compression of these structures by the muscle cannot be ruled out.
