Median Nerve Anatomy

Deep group flexor digitorum profundus lateral flexor pollicis longus. The antecubital fossa is by definition the triangular area bounded by the pronator teres brachioradialis and a line drawn horizontally betwen the humeral epicondyles.

In the axilla the median nerve lies lateral to the axillary artery.

Median nerve anatomy. The median nerve is a nerve in humans and other animals in the upper limb. Distribution and anatomy of the median nerve. Motor superficial volar forearm group.

Careful examination can determine if there are abnormal functions of this median nerve. The median nerve is formed from a lateral root from the lateral cord and a medial root from the medial cord of the brachial plexus. It is one of the five main nerves originating from the brachial plexus.

It initially spans the length of the upper arm as it runs a course parallel to the brachial artery. The most common type of injury to the median nerve is called carpal tunnel syndrome. The median nerve is one of the major nerves that is critical to the normal function of the upper extremity.

The median nerve originates from the lateral and medial cords of the brachial plexus and has contributions from ventral roots of c5 c7 lateral cord and c8 and t1 medial cord. In the upper arm and near the shoulder the median nerve branches off of the brachial plexus. The median nerve is a major peripheral nerve of the upper limb.

It forms from nerve roots originating at c5 t1. The median nerve is one of the five terminal divisions of the brachial plexus. The median nerve travels deep in the antecubital fossa to its apex and passes between the heads of the pronator teres.

The convergence of the lateral and the medial cords form this nerve and it has contributions from all anterior rami of c5 t11234. Intermediate group flexor digitorum superficialis. Pronator teres flexor carpi radialis.

The median nerve is a major peripheral nerve and supplies the flexor muscles in the forearm except flexor carpi ulnaris and the ulnar head of flexor digitorum profundus which is supplied by the ulnar nerve. In this article we shall look at the anatomy of the median nerve its anatomical course motor and sensory functions and clinical correlations.
