C5 and C6 merge to establish the upper trunk, C7 continuously forms the middle trunk, and C8 and T1 merge to establish the lower trunk. Prefixed or postfixed formations in some cases involve C4 or T2, respectively. The subclavian nerve originates in both C5 and C6 and innervates the subclavius, a muscle that involves lifting the first ribs during respiration. The long thoracic nerve arises from C5, C6, and C7. This nerve innervates the serratus anterior, which draws the scapula laterally and is the prime mover in all forward-reaching and pushing actions.
The five on the left are considered “terminal branches”. There have been several variations reported in the branching pattern but these are very rare. Anatomical illustration of the brachial plexus with areas of roots, trunks, divisions and cords marked. Clicking on names of branches will link to their Wikipedia entry.
Diagrammatic representation of the brachial plexus using colour to illustrate the contributions of each nerve root to the branches. The brachial plexus, including all branches of the C5-T1 ventral primary rami. Includes mnemonics for learning the plexus’s connections and branches. Innervates the skin of the lateral shoulder and arm: shoulder joint. Also superficial branch of radial nerve supplies back of the hand, including the web of skin between the thumb and index finger. The brachial plexus communicates through the sympathetic trunk via gray rami communicantes that join the plexus roots.
