MUSCLES OF THE SHOULDER 



CUT je" THE MUSCLES ON THE OUTSIDE OF THE SHOULDER. 



a and b, in Fig. 35, represent a portion of the Trapezius mus- 

 -\e. Its use is to elevate and support the shoulder-blade — to 

 ■p- gg raise it and likewise 



to draw it backward. 

 A portion of it is 

 represented as turned 

 back, to show the 

 muscles beneath. 



A moment's consid- 

 eration will convince 

 the reader that al- 

 though a low fore- 

 hand and thick shoul- 

 der are very properly 

 objected to, yet still 

 some fullness and 

 fleshiness are necessa- 

 ry, even about the 

 withers ; otherwise, 

 although there may 

 be height of withers, 

 and obliquity of shoul- 

 der, to give extensive 

 action, there will not 

 be sufficient muscular 

 power to work the 

 machine with either 

 quickness or continu- 

 ance. 



At c is a portion of 

 the levator humeri 

 (the raiser of the shoul- 

 der). It is a muscle 

 of immense power and 

 great utility, raising 

 and drawing forward 

 the shoulder and the 

 arm, or, when these 

 are fixed, turning the head and neck if one only acts, and de- 

 pressing them if the muscles on both sides act at the same time. 

 AtVZ is a portion of the serratus magnus muscle, between the 

 shoulder and side of the chest, and constituting the bulk of the 

 lower part of the neck. 



At ^ is a small portion of the splenius muscle, /, represents a 

 inuscie sometimes described as a portion of the levator humeri
