Introduction: Biceps brachii muscle is one of the powerful muscles in the anterior compartment of arm. It is supplied by musculocutaneous nerve. Normally, the muscle takes origin by two heads: long head and short head. Sometimes it takes origin as supernumerary heads. It inserts on the posterior part of radial tuberosity of radius bone. It maintains the stability of the shoulder joint. It crosses two joints: shoulder and elbow joint. Case report: In the present study, we found variation in the distal fibres which continued as flexor carpi radialis bilaterally. Several studies have been carried out about the origin of the muscles but few studies found regarding the variations in its insertion. Such finding may help the orthopedic surgeons for arthroscopy and surgical procedures.
Introduction: The musculocutaneous nerve is one of the branches from the lateral cord of brachial plexus. This nerve is solely devoted to the flexor compartment of arm hence it is called as nerve of arm. Numerous studies have been reported about the variations of this nerve but the real prevalence is still unknown, whereas, it may be hypothetical. Case report: This study shows a rare branching pattern where a thin nerve takes origin from the medial fasciculus of brachial plexus which then pierces the coracobrachialis and lies between the biceps brachii and brachialis. The nerve then pierces the biceps to supply the skin over the lateral surface of forearm. The median nerve took over the muscular branches of musculocutaneous nerve by giving off the branches to both biceps and brachialis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
