Variations in branching pattern of musculocutaneous nerve with respect to communicating branch between musculocutaneous and median nerve
Journal Title: International Journal of Anatomical Variations - Year 2018, Vol 11, Issue 3
Abstract
Aim: To study and classify the variations in branching of musculocutaneous nerve when the communicating branch is present between median nerve and musculocutaneous nerve. Methods: The study was conducted on 60 upper limbs from 30 embalmed cadavers. Stepwise dissection of axilla and arm was carried out and formation of brachial plexus and its branches were studied. Variations from the normal pattern were noted and photographed. Results: Communicating branch between musculocutaneous nerve and median nerve was observed in 21 of 60 upper limbs specimen studied (36.66%). In these specimens, variations in the branching pattern of musculocutaneous nerve were observed. These variations are described and discussed in the study Conclusions: Knowledge of the variations involving musculocutaneous nerve when communicating branch between musculocutaneous nerve and median nerve is present is clinically important in the evaluation and diagnosis of unusual presentations of peripheral nerve injuries, and effective management of the upper limb motor deficits caused by them.

Arteria lusoria, truncus bicaroticus, variant left vertebral artery
The normal aorta has three branches from its arch, the brachiocephalic trunk, the left common carotid and the left subclavian artery. Variations in the branching pattern of the aortic arch are not uncommon. We report a c...

Bilateral pectoralis major and pectoralis quartus variants: A conjoined tendon passing through the inter tubercular groove
The pectoralis major has been described to insert on to the lateral lip of the intertubercular groove of the humerus. The pectoralis quartus is a variant that runs parallel to the lateral border of the pectoralis major....
