The Lateral Pectoral Nerve (also known as the lateral anterior thoracic nerve) is a nerve in the human body that originates from the brachial plexus, specifically the anterior divisions of the upper and middle trunks.

Anatomy

The lateral pectoral nerve typically arises from the C5-C7 nerve roots of the brachial plexus. It descends to innervate the pectoralis major muscle, a large muscle in the upper chest.

Function

The primary function of the lateral pectoral nerve is to provide motor innervation to the pectoralis major muscle. This muscle is responsible for movements of the shoulder joint, including flexion, adduction, and medial rotation.

Clinical Significance

Damage to the lateral pectoral nerve can result in weakness or paralysis of the pectoralis major muscle, affecting the ability to move the shoulder joint. This can occur due to trauma, surgery, or conditions such as brachial plexus neuropathy.
