Brachial plexus & applied
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 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.

Medial pectoral nerve Origin, course and function Kenhub
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.

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.

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.

The median nerve is a major peripheral nerve of the upper limb. In this article, we shall look at the anatomy of the median nerve - its anatomical course, motor and sensory functions, and clinical correlations. Overview Nerve roots: C6 - T1 (also contains fibres from C5 in some individuals).

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 ( 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.

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
