Tlie vessels and nerves are tlien easily isolated, the formerbeing ligatured and the latter divided. The subscapular artery and nerves can begrasped and dealt with.

Itis inserted into the deltoid tubercle of the shaft of the humerus. Action.—Abducts the humerus to a right angle with the glenoidfossa of the scapula. Assists in drawing the arm forward (ventrally)and backward (dorsally).

This page from Cunningham's Textbook of Anatomy details the origins and actions of muscles such as the deltoid, triceps brachii, and latissimus dorsi, focusing on their role in movement and their nerve supply. It is a vital reference for understanding human muscular anatomy and the location of common injuries.-stock-foto
