Axillary sheath
Axillary artery and its branches - anterior view of right upper limb and thorax. (Axillary sheath not labeled, but region is visible.)
Gray's	subject #149 586

The first portion of the axillary artery is enclosed, together with the axillary vein and the brachial plexus, in a fibrous sheath—the axillary sheath—continuous above with the deep cervical fascia.

A brachial plexus nerve block can be achieved by injecting anaesthetic into this area.^[1]
