APPLIED ANATOMY. 



The constriction surrounding the head of the scapula is known as the anatomical 

 neck, in contradistinction to the surgical neck, which name has been given to that 

 portion indicated by a line drawn through the suprascapular notch and passing 

 beneath the spine and to the inside of the attachment of the long head of the triceps 

 muscle just below the lower edge of the glenoid cavity. 



The angles and borders and spine are important landmarks in physical diagnosis 

 and the coracoid and acromion processes in injuries. 



In the upper border of the bone at its junction with the base of the coracoid 

 process is a deep notch called the suprascapular notch (incisura scapulce), the supra-

scapular nerve passes through it. The artery passes over it. From the edge of the 

 bone just behind the notch arises the omohyoid muscle, an important guide in opera- 

 tions on the neck. 



The body of the scapula on its under surface is flat and rests on the thorax from 

 the second to the seventh and nearly to the eighth rib. Its movements on the chest 

 are free and follow those of the arm. It rises and falls, glides forward and backward, 

 and also rotates on an anteroposterior axis. 



When using any portion of the scapula as a landmark it is customary to have 

 the arm hanging by the side; if it is otherwise the position of the bone will be 

 changed, and the relations of its projections to the surrounding parts are altered. 

 The scapula is sometimes fractured directly across its body below the spine. One 

 should endeavor to fix in mind especially the relation of the acromion and coracoid 

 processes to the head, with its glenoid cavity, and the rest of the bone.
