flexor muscles Biceps brachial, Coracobraquial and Brachial anterior, which will be innervated by the musculocutaneous nerve

will find the extensor muscle brachial triceps, which is innervated by the radial nerve.

FOREARM

It is formed by the ulna and radius. It articulates in its proximal portion with the humerus and in its distal portion with the carpianos. This region will be irrigated by the ulnar artery and the radial artery.
