Three headed Biceps brachii with variant communication between median and musculocutaneous nerve. International Journal of Anatomy Physiology and Biochemistry 2017;4(12):1-5. A bstract : A three-headed biceps brachii muscle and variant communication between the median and musculocutaneous nerves have been well documented in the available literature. However, co-existence of these variations is rare. In this study we aimed to describe coexistence of neuro-muscular variations in the upper limb and discuss their embryological and clinical importance. Keywords: third head, biceps brachii, musculocutaneous nerve, median nerve Introduction: The biceps brachii muscle houses the flexor compartment of arm and is a strong supinator and flexor of forearm. The long head (LHB) arises from the supraglenoid tubercle of scapula and short head (SHB) from tip of coracoid process with coracobrachialis in a common tendon. In lower third of arm the two heads join and insert into the radial tuberosity, while some aponeurotic fibres, the bicipital aponeurosis, radiates into the ulnar part of the antebrachial fascia. 1 Variations in relation to heads of origin of biceps brachii in the form of accessory fleshy fibres from coracoid process, pectoralis major tendon, head of humerus, articular capsule of humerus or shaft of humerus (the humeral head) itself are frequent. 2 The median (MN), musculocutaneous (MCN) and ulnar nerves after their origin from the brachial plexus, pass through the anterior compartment of the arm without receiving any branch from any nerve in the neighbourhood. 3 Although the communications between the different nerves in the arm are rare, those between the median nerve and musculocutaneous nerve have been described from nineteenth century. 4 Dr Amit Tirpude Department of Anatomy AIIMS Bhubneshwar Orissa (India) +91- amit_tirpud e2005@rediffmail.com CASE REPORT INTERNA TIONA L JOURNA L OF A NA TOMY PHYSIOLOGY A ND BIOCHEMISTRY
