Third head of biceps brachii in anterior compartment of left arm - A Case Report

Abstract

Biceps brachii is a flexor of elbow joint and also a powerful supinator of the forearm present in the anterior compartment of arm and usually it originates from two head as its name indicating one is long head of biceps originating from supraglenoid tubercle of scapula and another one is short head which is originating from coracoids process of scapula. During routine dissection for Ayurvedic undergraduates, In the department of Shareera Rachana (Anatomy) in SDM Trust’s Ayurvedic Medical College, Terdal, Tq. Jamakhandi, Dist. Bagalkot, we found that third head of biceps brachii was originating from medial side of shaft of humerus which is just below the insertion of coracobrachialis along with the intramuscular septa and inserting into the radial tuberosity along with long and short head of biceps. Such variations are important for clinicians and surgeons for diagnostic and surgical procedures of the upper limb.
