The medial pectoral nerve is 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 of the pectoralis major muscle. It runs along the inferior border of the pectoralis minor muscle.
Pectoralis Major Muscle Attachment, Action & Innervation
Introduction The long thoracic nerve, also referred to as the external respiratory nerve of Bell or posterior thoracic nerve, arises from the upper portion of the superior trunk of the brachial plexus and typically receives contributions from cervical nerve roots C5, C6, and C7.

The median nerve is a sensory and motor nerve of the arm (or upper limb ). It arises from the lateral and medial cords of the brachial plexus, originating in the spinal cord, and runs through the anterior portion of the arm and forearm before finishing its path at the hand and digits (fingers). The median nerve innervates some of the major.

The medial pectoral nerve gives rise to muscular branches that mainly supply the pectoralis major muscle. This muscle is involved in adduction, internal rotation, flexion and extension of the arm at the shoulder joint, as well as drawing of the scapula anteroinferiorly at the scapulothoracic joint.
Pectoral Region Muscles Anatomy Earth's Lab
The medial pectoral nerve is a peripheral nerve that arises from the brachial plexus. The brachial plexus is formed by the ventral rami of C5 through T1 to form trunks. The trunks form anterior and posterior divisions, which in turn form cords, and the cords end as terminal branches.

The medial pectoral nerve arises from the medial cord of the brachial plexus and is composed of branches of C8 and T1. A few branches transect the pectoralis minor muscle and enter the PM to provide motor control of the sternocostal head of the muscle. These nerves are transected as they are encountered in the surgical dissection.

The medial pectoral nerve, also called the medial anterior thoracic nerve, is a branch of the medial cord of the brachial plexus. Upon originating, the nerve travels together with the axillary artery and vein, being located between them. The medial pectoral nerve is solely a motor nerve.

The medial pectoral nerve lies posterior to the axillary artery and anterior to the axillary vein. Along its course it receives a communicating branch from the lateral pectoral nerve to form a loop (ansa pectoralis) which runs anteriorly to both the axillary artery and vein. Variant anatomy

Medial pectoral nerve Origin, course and function Kenhub
The lateral pectoral nerve typically origins from the spinal nerve roots C5-C7 and branches off the lateral cord of the brachial plexus. It runs across the superior-medial margin of the minor pectoral muscle piercing the clavipectoral fascia (see next page) and enters the fascial space between the minor and major pectoral muscles; it innervates the two pectoral muscles
