Pectoral Region Muscles Anatomy Earth's Lab

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.

Type: The medial pectoral nerve is a motor nerve, serving to innervate specific muscles in the pectoral (chest) region. Origin: It arises from the medial cord of the brachial plexus, typically receiving contributions from the C8 and T1 nerve roots.

Anatomy, Shoulder and Upper Limb, Muscles - StatPearls - NCBI Bookshelf The upper limb comprises many muscles which are organized into anatomical compartments. These muscles act on the various joints of the hand, arm, and shoulder, maintaining tone, providing stability and allowing precise fluid movement.

Pectoralis Major Muscle Attachment, Action & Innervation

superior vena cava. . The upper limb is innervated by nerves of the. brachial plexus. , a somatic neural network formed by the anterior branches of the spinal nerves C5-T1. The musculocutaneous, axillary, radial, ulnar, and median nerves are the most important sensorimotor nerves of the upper limb.

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.

Overview Musculoskeletal Key

The lateral cord gives rise to the lateral pectoral nerve. The medial cord gives rise to medial pectoral nerve, medial cutaneous nerve of the arm, and medial cutaneous nerve of the forearm. The posterior cord of the brachial plexus gives off the upper subscapular nerve, thoracodorsal nerve and lower subscapular nerve.

Brachial plexus & applied

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.

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

Cervical spine Anatomy, ligaments, nerves and injury Kenhub

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 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.

Medial pectoral nerve Origin, course and function Kenhub

The medial pectoral nerve also carries axons from spinal cord segments C5, C6, and C7 via a communicating branch from the lateral pectoral nerve. Course. The medial pectoral nerve emerges from the medial cord medial to the second portion of the axillary artery. Typically, its origin is proximal to the origin of both the medial brachial.

Pectoralis Minor Origin, Insertion, Nerve Supply & Action » How To Relief

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.

Nerves of the Upper Limb Flashcards Easy Notecards

The medial pectoral nerve ( medial anterior thoracic; fasciculus medialis ) arises from the medial cord of the plexus and through it from the eighth cervical and first thoracic. It passes behind the first part of the axillary artery, curves forward between the axillary artery and vein, and unites in front of the artery with a filament from the.
