156 Mtifcles of the Neck, Be. [Book IX. 



It pulls the head backwards, and affifts a little in its 

 rotation. 



The retlus capitis pofticus minor arifes from a little 

 protuberance in the middle of the back part of the firft 

 vertebra of the neck, and is inferted near the foramen 

 magnum of the os occipitis. It aflifts in moving the 

 head bdckwards. 



The obliquus capitis fuperior arifes from the tranf- 

 verfe procefs of the nrft vertebra of the neck, and is 

 inferted into the os occipitis. It draws the head back- 

 wards.] 



The obliquus capitis inferior arifes from the fpinous 

 procefs of the fecond vertebra of the neck, and is in- 

 ferted into the tranfverfe procefs of the firft vertebra 

 of the neck. This mufcle acts very powerfully in 

 giving a rotatory motion to the head. 



On the fide of the neck are thefcalenus anticus, which 

 arifes from the fourth, fifth, and fixth tranfverfe pro- 

 cefies of the vertebrae of the neck, and is inferted into 

 the upper part of the firft rib, 



The fcalenus medius, which proceeds from all 

 the tranfverfe proceffes of the vertebras of the neck, 

 ^nd is inferted into the upper and outer part of the 

 firft rib. 



The fcalenus pofticus, which arifes from the fifth 

 and fixth tranfverfe proceffes of the vertebras of the 

 neck, and is inferred into the upper part of the fe-

The effect of all the fcaleni is to bend the neck to 

 one fide, or, when the neck is fixed, to raife the ribs and 

 dilate the thorax. 



There are a number of frrall mufcles fituated between 

 the fpinous and tranfverfe proceffes of contiguous ver- 

 tebras, fome of which approach fo nearly to the nature
