Anatomical terminology

The axillary sheath is a fibrous sheath that encloses the first portion of the axillary artery, together with the axillary vein and the brachial plexus. It is an extension of the deep cervical fascia.

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