The nerve to serratus anterior is a branch of the brachial plexus and arises from the roots C5, 6, 7.

Winging of scapula is a condition in which the medial border of a person's scapula is abnormally positioned outward and backward. The resulting appearance of the upper back is said to be wing-like as the inferior angle of the shoulder blade protrudes backward rather than remaining almost flat as in normal people.
