The triangular space or medial axillary space is an axillary space that contains the scapular circumflex vessels.[1]

It is bounded by the Teres minor superiorly, the Teres major inferiorly, and the long head of the Triceps laterally.

The triangular interval transmits the radial nerve and the Profunda brachii artery also called as thedeep artery of the arm.
