STRUCTURES IN AXILLARY SPACE 



369 



skin and fascia crossing from the thorax to the arm. The walls 

 of the space are formed by muscles the serratus (principally) on 

 the medial wall, covering the ribs; the long tendon of the biceps 

 in its groove on the lateral wall; the pectoral muscles in the anterior 

 wall, and the subscapularis, latissimus dorsi and teres major in the 

 posterior wall. 



The importance of this space is due to the large vessels and 

 nerves, and the lymph nodes, which are found in it. The vessels 

 are the axillary artery and vein; the nerves are the brachial plexus 

 and branches. A chain of superficial lymph nodes lies under the 

 border of the pectoralis major, and a collection of deep ones is 

 grouped around the large vessels; there are also a few near the 

 posterior wall.
