A Study onthe Variations of Musculo-Cutaneous Nerve In Relation To Coracobrachialis & Median Nerve
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 3
Abstract
The musculocutaneous nerve is a branch coming from lateral cord of brachial plexus. After origin it enters the arm by piercing the coracobrachialis and supplies it along with other muscles of arm, then it continue into the forearm as lateral cutaneous of forearm. Variations in the branching pattern of nerve are not uncommon but have clinical significance during surgical procedures involving brachial plexus block and in diagnostic clinical neurophysiology.Methods:In the present study, 100 upper limbs of 50 cadavers preserved with formalin available in the department of anatomy were dissected and the formation, course, relations and branches of musculocutaneous nerve in the axilla, arm, forearm and hand were observed and compared with the previous studies of various authors.Results:In the present study, 8% of the specimens showed communicating branches with the musculocutaneous nerve &in 2% of the specimens the median nerve was innervating anterior compartment of the arm along with the absence of musculocutaneous nerve.
