| Anatomical terminology |
The triangular interval (also known as the lateral triangular space[1] and lower triangular space[2]) is a space found in the axilla.
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.)
Contents
The radial nerve and profunda brachii pass through the triangular interval.
