outer portion (*//) is an immediate continuation of the ///. recfv.9 

 atjiloiiihiis. which passes into this 

 muscle at about the fifth hixcrijj- 

 tio tendinea. The muscle passes 

 forwards on the upper surface of 

 the coracoid and of the clavicle, 

 under the pericardium towards 

 the hyoid bone ; here the muscle, 

 hitherto horizontal, suddenly be- 

 comes (compare Fig. 60) ver- 

 tical, and passes between the 

 two insertions of the m. genio- 

 Jiyoulevx. and is inserted for a 

 considerable length into the lower 

 surface of the hyoid bone and the 

 anterior extremity of the posterior 

 cornu.

A thin, fiat muscle, narrow above, but broadening rapidly 

 below, which arising from the outer extremity of the prootic 

 bone, partially surrounds the pharynx below, iuto which some of 

 its fibres are inserted ; it is attached to the ventral surface 

 <>f the body of the hyoid bone, near the lateral notch. The 

 chief action of this muscle appears to be that of a ///. conflict or 

 }Jiari/'nf/>*.
