THE VASCULAE SYSTEM, 



c. The Art. scapnlaris posterior (Fig. 150^ 3), a small branch 

 arising opposite at the tip of the second transverse process and 

 passing backwards over the MM. transverso-scajmlares, to which it is 

 distributed. 



d. The Art. scajmlaris superior (Fig. 150, 4) accompanies several 

 nerves between the M, suhscapularis, 31. transverso-scapularis major,

and the long head of the M. triceps towards the dorsal surface, 

 where it is distributed to the M3I. infrasjnnatus, latissimns dorsi, etc. 



e. The Ramtis aitaneus maxillaris. 



f. The Art. suhscapularis (Fig. 150^ 6) is distributed in the su.b- 

 scapular muscle. 



A. The brachial artery [Arteria b)-ackialis), (Fig. 150) accom- 

 panies the brachial nerve under cover of the long head of the 

 M. triceps and over its inner head to the Plica cuhiti, into which it 

 sinks near the tendon of the 31. sternoradialis ; beyond this point it 

 is continued as the ulnar artery. In its course the brachial artery 

 gives off : — 



a. The Arteria pectoralis (Fig. 150 j»;). 



b. The Arteiia cutanea medialis superior (Fig. 150 c). 



c. The radial arterj {Arteria radialis), (Fig. 150R) which winds
