THE SCAPULA. 



The superior edge or costa is situated between the ante- 

 rior and superior angles, is thin and short ; and has at its 

 fore-part a notch, which is formed into a foramen by a 

 ligament, and transmits the supra-scapular nerve. The 

 F[ G . 215. oino-hyoid, supra-spinatus, and 



sub-scapular muscles are also at- 

 tached to this edge. 



At its anterior portion the cora- 

 coid process arises. This is long 

 and narrow, runs upward and 

 forward, and bounds the glenoid 

 cavity internally. Its superior 

 surface is rough for the attach- 

 ment of ligaments, the inferior is 

 smooth for the sub-scapular mus- 

 cle. The extremity of this process 

 frequently presents three distinct 

 surfaces, the inner of which has 

 the pectoralis minor inserted into 

 it; the middle gives origin to the coraco-brachialis, and 

 the outer to the short head of the biceps. 



The anterior or axillary edge looks downward and back- 

 ward, and extends from the anterior to the inferior angle. 

 It is the thickest of the three edges, and gives attachment 

 to the teres major, teres minor, and long head of the 

 triceps. The posterior or vertebral edge, called also the 

 base, extends from the superior to the inferior angle, and 

 is the longest of the three margins. Below the spine are 

 attached to it the rhomboideus major, opposite the origin 

 of the spine the rhomboideus minor, above the spine the 

 levator scapulae, and along its whole extent the inser- 

 tion of the serratus major anticus. At the junction of the 

 superior costa and the base is the superior angle. At the
