[edit] Borders
Two of its borders are as follows:
- teres major - superior
- long head of the triceps brachii - medial
Some sources state the lateral border is the humerus,[3][4] while others define it as the lateral head of the triceps,[5] or the medial head of the triceps.[2] (The effective difference is relatively minor, though.)
[edit] Contents
The radial nerve and profunda brachii pass through the triangular interval, on their way to the posterior compartment of the arm.
