Method:
During the routine dissection of a male cadaver for teaching undergraduate medical students, a variation was seen in the morphology of coracobrachialis muscle.
Results:
The presence of an anomalous head of coracobrachialis muscle which had muscular origin from an abnormal site on coracoid process and thin tendinous insertion at the junction of brachialis and triceps muscle in common with insertion of coracobrachialis muscle to the medial surface of the middle of the shaft of the humerus.
Conclusion:
Coracobrachialis muscle can have variant origin related to its embryogenesis with its clinical and surgical significance.
