The medial cutaneous nerve of the forearm (also known as the medial antebrachial cutaneous nerve) is a sensory branch of the medial cord of the brachial plexus derived from the ventral rami of spinal nerves C8-T1. It provides sensory innervation to the skin of the medial forearm and skin overlying the olecranon.
Cutaneous innervation of the upper limbs is the nerve supply to areas of the skin of the upper limbs (including the arm, forearm, and hand) which are supplied by specific cutaneous nerves. Modern texts are in agreement about which areas of the skin are served by which cutaneous nerves, but there are minor variations in some of the details.
The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus. The median nerve originates from the lateral and medial cords of the brachial plexus, [1] and has contributions from ventral roots of C6-C7 (lateral cord) and C8 and T1 (medial cord). [1] [2]
The medial brachial cutaneous nerve (lesser internal cutaneous nerve; medial cutaneous nerve of arm) is a sensory branch of the medial cord of the brachial plexus derived from spinal nerves C8-T1. It provides sensory innervation to the medial arm. It descends accompanied by the basilic vein. [1]
The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.
The medial cord is the part of the brachial plexus formed by of the anterior division of the lower trunk (C8-T1). [1] Its name comes from it being medial to the axillary artery as it passes through the axilla. The other cords of the brachial plexus are the posterior cord and lateral cord.
