Deltoid muscle


The shoulder is made up of several muscles, one of which is the deltoid muscle that resembles a triangle. The deltoid muscle is attached to the clavicle, as well as to the scapula at two distinct points. Three muscle bundles form the deltoid muscle. These bundles stretch over the humerus and aid in forward arm flexion, rotation, and bending, as well as in abduction movements of the shoulder. The deltoid muscle is innervated by the axillary nerve.
