Axillary artery and its branches - anterior view of right upper limb and thorax (axillary sheath not labeled, but region is visible)
Anatomical terminology
[edit on Wikidata]
The axillary sheath is a fibrous sheath that encloses the axillary artery and the three cords of the brachial plexus to form the neurovascular bundle.[1][2][3] It is surrounded by the axillary fat.[1][2] It is an extension of the prevertebral fascia of the deep cervical fascia[citation needed] and is continuous with the carotid sheath at the venous angle.[4]
A brachial plexus nerve block can be achieved by injecting anaesthetic into this area.[5][6]
