Classification of communicationsīetween the musculocutaneous and median nerves. Williams PL, Bannister LH, Berry M, Collins P, Dyson M, Dussek JE,Įt al. Musculocutaneous and median nerves in human. Of connections between the musculocutaneous and median nerves in theĨ. Choi D, Rodriguez-Niedenfuhr M, Vazquez T, Parkin I, Sanudo JR. Of coracobrachialis, biceps brachii and brachialis from the median nerve. Absence of the musculocutaneous nerveand innervation Comparative studies upon the morphology and distribution of Variabilities and their clinical significance. The distribution of nerves in the upper limb, with reference to The brachial plexus of nerves in man, the variations in itsįormation and branches. Since axilla and upper half of the arm are challenging areas for surgical procedures, so the unusual variations being reported in this case may help the surgeons of different specialties in exploration of neuronal tumor, shoulder reconstructive surgery shoulder arthroscopy, and using the coracobrachialis flap for different surgical purposes.ġ. This was witnessed in the infraclavicular part of the brachial plexus during the routine gross anatomy dissection of the left upper extremity in a 35-year-old Indian male cadaver. The present case report describes an unusual unilateral course of lateral cord piercing the coracobrachialis and ensuing path followed by its various branches as well as unusually low-level formation of median nerve from lateral and medial roots coming from the lateral and medial cord of brachial plexus, respectively. Variations are commonly observed and being reported in the formation of lateral cord of brachial plexus and in the communication of branches of lateral cord of brachial plexus, but formation of median nerve by lateral root of median nerve from lateral cord and medial root of median nerve from medial cord at a substantially low level is quite unusual and the case reports regarding piercing of the coracobrachialis by lateral cord of brachial plexus are infrequent.
