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 .
Posterior median line; Other anatomical lines include: Mid-pupillary line: A line running vertically down the face through the midpoint of the pupil when looking directly forward. Mid-inguinal point: A point midway between the anterior superior iliac spine and the pubic symphysis.
The median nerve is a nerve in humans and other animals in the upper limb. It is one of the five main nerves originating from the brachial plexus. The median nerve originates from the lateral and medial cords of the brachial plexus, [1] and has contributions from ventral roots of C6-C7 (lateral cord) and C8 and T1 (medial cord). [1] [2]

Along the arms and the legs, the pattern is different: the dermatomes run longitudinally along the limbs. Although the general pattern is similar in all people, the precise areas of innervation are as unique to an individual as fingerprints. An area of skin innervated by a single nerve is called a peripheral nerve field.
The lateral root of median nerve is a source of the median nerve, originating off the lateral cord of the brachial plexus. [1] It is typically one of two nerve roots forming the median nerve, the other being the medial root, [1] although anatomical variations in which the median nerve instead has three or four nerve roots have been described in medical literature.
In anatomy, arterial tree is used to refer to all arteries and/or the branching pattern of the arteries. This article regards the human arterial tree. Starting from the aorta: the following are the parts
