Identify the highlighted structure. |
Teres major (note the posterior view of the specimen). |
|
Name two vascular structures that run deep the muscle highlighted in purple. |
The muscle highlighted in purple is pectoralis minor. The two vascular structures that run deep to this muscle is the axillary vein and artery. |
