Left Infant Brachial Plexus – No Text

This exhibit depicts the anatomy of the infant brachial plexus and the innervation of the upper limb. The brachial plexus is classified into five different segments: roots, trunks, divisions, cords, and terminal branches. The lateral cord (with contributions from nerve roots C5,C6, and C7) supplies the pectoralis via the lateral pectoral nerve, and the biceps brachii. The medial cord (with contributions from nerve roots C8 and T1) supplies the pectoralis via the medial pectoral nerve, and the intrinsic muscles of the hand. Divisions from the lateral and medial cord join together to form the median nerve. The median nerve (with contributions from nerve roots C7, C8, and T1) supplies the pronator teres, flexor muscles of the fingers, and flexor muscles of the wrist. The posterior cord (with contributions from nerve roots C5, C6, C7, and C8) supplies the deltoid, posterior shoulder muscles, triceps brachii, latissimus dorsi, brachioradialis, extensor muscles of the fingers, extensor muscles of the wrist, extensor muscles of the thumb, and abductor muscles of the thumb.
