358 MUSCLES OF THE BACK AND NECK. 



when the neck is fixed, to elevate the ribs, and to dilate the 

 thorax. 



There are a number of small muscles situated between the 

 spinous and transverse processes of contiguous vertebrae ; which 

 are accordingly named, 



1. Interfpinales Cotti. 



The space between the spinous processes of the vertebrae of 

 the neck, most of which are bifurcated, is filled up with these 

 fleshy portions ; each of which 



Arises, double, from the spinous process of the cervical 

 vertebra below, and ascends to be 



Inserted, in the same manner, into the spinous process of the 

 vertebra above. They are five in number. 



Use. To draw these processes nearer to each other. 



2. Intertransversales Colli. 



They begin from the transverse process of the first vertebra 

 of the back, and fill up the spaces between the transverse 

 processes of the vertebrae of the neck, which are likewise 

 bifurcated ; and, consequently, there are six distinct double 

 muscles, which 



Arise from the inferior transverse process of each vertebra of 

 the neck, and first of the back, and are 



Inserted into the transverse processes next above. 



Use. To draw these processes towards each other, and turn 

 the neck a little to one side. 



Interspinales Dor si et Lumborum, and the Intertransver- 

 sales Dorsi, 



Are rather small tendons than muscles, serving to connect the 

 spinal and transverse processes. 



Intertransversales Lumborum, 



Are four distinct small bundles of flesh, which fill up the space 

 between the transverse processes of the vertebrae of the loins, 

 and serve to draw them towards each other.
