bauchiger Nackenmuskel, Splenius capitis). It 

 springs, by separate points, from the dorsal pro- 

 cesses of the four anterior body vertebras and the 

 six posterior neck vertebrae; it is convex on its 

 dorsal, weakly concave on its ventral surface; it 

 leads cephalad as a short, strong tendon by which it 

 is attached to the angle between the upper hinder 

 border of the skull, i.e. to the superior and lateral 

 occipital region. 



Sqiiamoso-cervicalis Medialis (Kopfbauchmuskel 

 [Splenius] or durchflochtener Muskel [Complexus], 

 Trachelo-mastoideus, Complexus). This muscle 

 lies laterad and ventrad to the preceding and is at 

 times partly covered by it in its posterior half. It 

 arises from separate heads from the spinal pro- 

 cesses of the two anterior and six posterior cervical 

 vertebrae; beginning caudad, thin and sharp, it 

 gradually becomes thicker as it passes cephalad 

 until it becomes partially tendinous and inserts 

 itself on the hinder border of the squamosal, lat- 

 erad to the occipito-cervicalis medialis muscle. 



Epistropheo-vertebralis (Splenius colli). This 

 muscle springs from the spinous processes of the 

 most anterior three body vertebrae and the last 

 cervical vertebra ; it receives fibers from the articu- 

 lar processes and intermediate parts of the six 

 posterior cervical vertebra and is inserted on the 

 second cervical vertebra. 



Collo-sqiiamosiis (Splenius capitis, Nackenwar- 

 zenmuskel, Trachelo-mastoideus). Springs from
