Once again, we have lifted the arm up, and we are looking at the medial aspect of the brachium. The long head of the triceps brachii muscle (A) is extensive on this side too. It is partially covered by the thin sheet-like tensor fasciae antebrachii muscle (B). The fourth head of the triceps brachii muscle, the medial head (C), is partially covered by the median and ulnar nerves. The biceps brachii muscle (D) is in a more natural position than it was in the previous image.

If I had muscle A tagged on an exam, I would expect you to identify it as the long head of the triceps brachii muscle, not long head or long head of the triceps. Likewise, I will not accept biceps for muscle D, as there is a biceps femoris muscle in the hind limb.
