These names are not in use in England, but are suitable, and may well be adopted. Through the external axillary space the posterior circumflex nerve and vessels pass backwards; and through ternal axillary space the dorsal branch of the subscapular artery passes round the margin of the scapula into the infraspinous -Te.
