What is the name of this bone
Humerus
Deltoid tuberosity
The deltoid tuberosity (deltoid tubercle) is the rough, triangular prominence found at the middle third of the anterolateral surface of the humerus. It provides an insertion site for the deltoid muscle.

Medial Epicondyle of Humerus
Epicondylus medialis humeri
DESCRIPTION
The medial epicondyle (internal epicondyle) of humerus is the subcutaneous projection found at the distal end of the medial supracondylar ridge. It is more prominent than the lateral epicondyle of the humerus. The medial epicondyle contains the groove for ulnar nerve. It provides origin sites for the superficial group of muscles of the anterior compartment of the forearm, as well as an attachment site for the ulnar collateral ligament.
capitulum of humerus
Trochlea of Humerus
The subclavian vein
- first branch is the external jugular vein (the most superior vein)
Olecranon fossa
Internal jugular vein - it originates from the brachiocephalic vein
Thoracoacromial artery
- Axillary artery and branch
Lateral thoracic artery
- the second branch off of the axillary artery
- Course: Inferiorly along the lateral thoracic wall. Branches: Lateral mammary branches. Supplied Structures: Serratus anterior, pectoralis major and minor, and subscapularis muscles, axillary lymph nodes.
Subscapular artery - branches off from the axillary artery
Thoracodorsal artery - branches off of the sub scapular artery
Circumflex scapular artery - branches off of the sub scapular artery
Anterior circumflex humeral artery - branches off of the axillary artery
Posterior circumflex humeral artery - branches off of the axillary artery and wraps around the surgical neck of the humerus. Eventually, it will wrap around the anterior circumflex humeral artery
