Musculocutané nerve

The nerve musculocutané or musculocutaneous is a Nerf sensitivo-engine of the upper limb at the man.

Anatomy

The musculocutané nerve is born from the side beam of the Plexus brachial resulting from the former trunk of the higher branch and the former trunk of the average branch of the plexus brachial, in the area axillaire. It is the nerve of the inflection of the elbow

It crosses the lower part of the hollow axillaire, then perforates the muscle coraco-brachial to engage in the former cabin of the arm behind of the biceps brachial. When it arrives at the level of the fold of the elbow, in the furrow bicipital side, it crosses the fascia brachial, and finishes in a terminal section called side cutaneous nerve of the front armlever . The side cutaneous nerve of the front armlever is divided into two sensitive surface branches. These two branches pass ahead or behind from the cephalic median vein. The former branch walks on on the antéro-side face of the front armlever, the posterior branch goes outwards outwards towards the postéro-side area of the front armlever.
