1. Semi-S_pinalis Colli, 



Arises from the transverse processes of the uppermost six 

 vertebrae of the back, by as many distinct tendons ascending 

 obliquely under the complexus. 



Inserted into the spinous processes of all the vertebrae of 

 the neck, except the first and the last. 



Use. To extend the neck obliquely backwards. 



2. Transversalis Colli, 



Arises from the transverse processes of the five uppermost 

 vertebrae of the back, by as many tendinous and fleshy origins ; 

 runs between the trachelo mastoideus, and splenius colli and 

 cervicalis descendens. 



Inserted into the transverse processes of all the cervical ver- 

 tebrae, except the first and the last. 



Use. To turn the neck obliquely backwards, and a little to 

 one side. 



Below the posterior part of the occiput are, 



1, Rectus Capitis Posticus Major, 



Arises, fleshy, from the external part of the spinous process 

 of the second vertebra of the neck, and grows broader in its 

 ascent, which is not straight, but obliquely outwards. 



Inserted, tendinous and fleshy, into the os occipitis, near the 

 rectus capitis lateralis, and the insertion of the obliquus capitis 

 superior. 



Use. To pull the head backwards, and to assist a little in its 

 rotation. 



2. Rectis Capitis Posticus Minor. 



Arises, by a narrow beginning, close to its fellow, from a 

 little protuberance in the middle of the back part of the first 

 vertebra of the neck, its outer edge being covered by the rectus 

 major. 



Inserted, somewhat broad, into the sides of a dimple in the 

 OS occipitis, near its foramen magnum. 



C7se. To assist the rectus major in moving the head back- 

 wards.
