Lateral epicondylar ridge of humerus 8. Triceps brachii, lateral head m.	9. Medial epicondyle of humerus 10. Tendon m. triceps brachii 11. Triceps brachii, long head m.	12. Ulnar nerve 13. Basilic v. 14. Median nerve 15. Brachial a. and v. 16. Biceps brachii m.

This section is two below the preceding one (2 cm).

This section cuts the two remaining muscles of the anterior compartment, biceps brachii (16) and brachialis (2) muscles, and the single muscle of the posterior compartment of the arm, triceps brachii (8, 10, 11).

Brachioradialis (5) is increasing in size. Note how it and brachialis (2) surround the radial nerve (3), which supplies the two muscles, brachialis only partially.

The median nerve (14) retains its immediate proximity to the brachial artery (15).

The humerus is becoming less rounded and more triangular in appearance due to the development of the lateral epicondylar ridge (7) and medial epicondyle (9).

Note the hematoma associated with the cephalic vein (1) and spreading into the surrounding superficial (fatty) fascia.
