148 SPECIAL ANATOMY. 



245. 2. Rectus capitis posticus minor. 



Pos. : internal and close to the last, before and covered by it. 

 Or. : Atlas (tuberc. post.). Ins. : Linea semicircular, inferior. 

 [In the fossa below this.] Use : to extend the head. 



246. 3. Obliquus capitis superior s. minor. 



Pos. : external and close to the last muscles, oblique. Or. : 

 Atlas (proc. transv.). Ins. : Os occiput (between the lin. semic. 

 infer, and superior,) 'behind proc. mastoid. Use : to draw the 

 head backwards, or rotate it towards the opposite side. 



247. 4. Obliquus capitis inferior s. major. 



Pos. : oblique, outwards and upwards, covered by complex. 

 and trachelo-mast. Or. : Epistropheus (on the side of proc. 

 spinos.). Ins. : Atlas (proc. transv.). Use : to rotate the Atlas 

 (with the head and face) towards its own side. 



248. 5. Multijidus spinse. 



Pos. : between the spinous and transverse processes of the 

 entire vertebral column ; immediately upon the vertebrae (and ro- 

 tatores dorsi; covered by longiss., spinalis dorsi, semispin. dorsi 

 and cervicis, complexus. Or.: Lateral parts of the Sacrum; 

 proc. transv. (inferior vertebrae) and obliqui (in the neck). Ins. : 

 proc. spinosi (superior vert.). Use : the separate fasciculi rotate 

 the vertebrae ; the entire muscle extends the column. 



249. 6. Inter spinales. 



In the spaces between the Proc. spinosi, of the cervical (second 

 to the seventh) and lumbar vertebrae. Use: to extend the verte- 

 bral column. 



250. 7. Intertransver sales. 



In the spaces between Proc. transversi ; in the neck : externi 

 and interni (generally wanting in the back). Use : to draw the 

 vertebrae, and consequently the column, sideways. 



251. 8. Rotator es dorsi. 



Pos. : covered by multifidus spinse, on the dorsal vertebrae, 

 transverse. Or. : proc. transversi (superior border). Ins. : Arch 

 of the vert, next above. 



Nerves: rr. poslerr. nn. fpinalium (from the first to the eighth).
