THE MUSCULATURE OF THE TRUNK. 283 



being joined in its passage by the third descending 

 fasciculus from the longus colli posticus (the fasciculi 

 obliqui of the longus colli posticus, or rather the third 

 one of the series as so described by Owen ?). 



Now, the next fasciculus of the muscle we have 

 under consideration arises from the transverse process 

 of the tenth cervical vertebra, winds about, parallel 

 with the last, to skip the ninth, and be inserted into 

 the hinder margin of the postzygapophysis of the 

 eighth vertebra ; it also being joined by the next 

 fasciculus in order descending from the longus colli 

 posticus. 



The next three fasciculi arise in a similar way, but 

 in addition to being attached to the postzygapo- 

 physes they continue forwards to make an insertion 

 also upon the neural spines of the alternate vertebrae 

 in turn, being inserted in fact with the anterior set of 

 descending fasciculi from the longus colli posticus. 



The insertion of the last two slips of the obliquus 

 colli again differ. The most posterior of these two 

 arises from the transverse process of the sixth vertebra, 

 and passing less obliquely up the neck, becomes in- 

 serted into the extremity of the diapophysis of the 

 fourth vertebra, by a strong tendon ; the outermost 

 carneous fibres of the fasciculus, still continuing towards 

 the head, make another tendinous attachment to the 

 outer extremity of the transverse process of the third 

 vertebra. 



Now the last or most anterior fasciculus of this series 

 arises from the transverse process of the fifth vertebra, 

 and passing under and parallel with the last, is in- 

 serted with its leading tendon into the extremity of 

 the diapophysis of the third vertebra. This completes 

 one of the most complicated systems of muscles that
