neck. It arises from the tips of the ribs of the 

 first and second cervical vertebrae (where it is 

 fused with the sterno-atlanticus muscle), and 

 also from the transverse process of the third and 

 fourth cervical vertebrae; it goes with diverging 

 fibers to the entire anterior border of the scapula. 



Thoraci-scapularis Superficialis (Serratus super- 

 ficialis, Pectoralis minor, Hinterer Theil des inneren 

 grosseren Ruckwartsziehers, Pars posterior m. 

 serrati antici majoris, Theil des Grand dentele, 

 Serrati posteriores, Latissimus dorsi scapulo- 

 costalis). A strong muscle of three prongs that 

 go directly, by superficial fibers, over into the 

 oblique abdominal muscle and meet the ribs. 

 The first and smallest prong arises from the 

 under end of the rib of the ninth vertebra (last 

 cervical); the second and medium-sized prong 

 comes from the uncinate process of the tenth rib 

 (first thoracic) and from beneath the uncinate 

 process of the second thoracic rib; the third and 

 strongest prong takes its origin from the uncinate 

 processes of the second and third thoracic ribs. 

 All three prongs unite to form a broad, homogen- 

 eous muscle which passes forward and above to 

 the hinder border of the scapula, upon whose entire 

 surface, except at the lower end, it is inserted.
