The medial pectoral nerve (also known as the medial anterior thoracic nerve) is (typically) a branch of the medial cord of the brachial plexus and is derived from spinal nerve roots C8-T1. It provides motor innervation to the pectoralis minor muscle, and the lower half (sternal part) of the pectoralis major muscle. It runs along the inferior border of the pectoralis minor muscle.[1]
Damage to the medial pectoral nerve can result in inability to elevate the shoulder.[1]
