Course of right axillary nerve
The specimen shown in the previous view has been dissected to illustrate the relations of the axillary nerve. The capsule of the shoulder joint (8) has been detached from the surgical neck of the humerus. The upper part of the humerus has been cut away. Veins have been removed.
