Abstract

Variation in biceps brachi and musculocutaneous nerve are frequent variations. In the present study there is variation in the origin of biceps brachii with a co-existance of unsual formation of median nerve.

Materials and methods:16 cadavers ( 32 upper limbs) were studied during 2013 -2016 as a part of routine dissection for MBBS students .

Observations: out of 16 cadavers studied, one male cadaver showed tricipital origin of biceps brachii bilaterally and unilateral variation in the communicating twigs between lateral cord and medial root of median nerve and ulnar nerve.

Conclusion: Variations in the origin of muscles can cause unusual bone displacement.  Variation in communications between median and other nerves of upper limb is important while evaluation of clinical neurophysiology, planning a surgery after trauma and understanding of  neurodysfuncton.

Key words: biceps brachii, lateral cord , median nerve, pectoralis major, ulnar nerve
