As muscles use the oxygen from the blood, it must be returned to the lungs to once again receive oxygen. Branches of the suprascapular artery, a branch of the thyrocervical trunk, also contribute. The bursae have both a nerve supply and mechanoreceptors which aid proprioceptive information of shoulder joint position. After they leave their point of origin, nerves then travel toward their destinations, branching out tree-like to supply nerve function to various tissues. There is also an important nerve that travels around the back of the shoulder joint to supply sensation to a small area of skin on the outside of the shoulder and motor signals to the deltoid muscle. The brachial plexus has many nerves that contribute to it, such as: Most of the shoulder nerves that provide sensation to the shoulder, upper arm, forearm, wrist, and hand are part of a network of nerves called the brachial plexus.
