Axillary space

Axillary space
Axillary space, between the teres major and teres minor muscles, and split into a medial and lateral part by the triceps brachii muscle.
Latin	spatium axillare

The axillary space is an anatomic space, bounded by teres major muscle, teres minor muscle and humerus. Furthermore, it is split into two parts, the lateral and medial, by the long head of triceps brachii muscle.

Medial axillary space

This space is triangular, and is therefore also called the triangular space. Scapular circumflex artery and scapular circumflex vein pass through it.

Lateral axillary space

This space is quadrangular, and therefore also called the quadrangular space. Nervus axillaris, posterior humeral circumflex artery and posterior humeral circumflex vein pass through it.
