When thefe a6l together, they bend the Head forv^^ard, but 

 when feparately, they draw it a httle to one Side. 



The Sple?iiian is reckoned the fecond' Pair, being the 

 firft of thofe which pull back the Head ', they arife from 

 the five uppermoft Vertebra of the Cheft, and the live 

 lowermoft of the Neck, with a nervous Beginning, afcen- 

 ding to the hinder part of the Head, where they are infert*' 

 ed. When thefe a6l together, they draw the Head back- 

 ward ; but when they ad fingly, they draw it a little to 

 one Side. 



The third Pair, named Compkxum^ or Trlgemhnmi^ 

 becaufe each of them arife with three Heads \ two from 

 the liril, fecond, fourth, and fifth tranfverfe Procefles of 

 the Cheff, and the third from the Ridge of the feventh Ver- 

 iebra of the Neck j all which uniting together, are inferted 

 in the Noll-bone. 



The third Puller back of the Head, or fourth Pair, 

 ■called Parvum Crajfum : Thefe are fituated under the for- 

 mer, ariling nervous from tlie tranfverfe Procelles of the 

 lix uppermoft Vertebras of the Neck ; but afterwards be- 

 coming liefhy, are carried obliquely upward, and are infert- 

 ed into the hindermoft Root of the Procerus rnammillaris. 

 When thefe ad fmgly, they incline the Head lightly back- 

 ward to one Side ; but when they act together, they bring 

 it llreight backward. 



The Retlum majus and Return minus, which make Mp 

 the fifth and fixth Pair, are feated one under the otlfer, and 

 are both inferted into the Noll, alfilting the fourth Pair in 

 their ALlion. 



The Obiiquum fuperius^ which is accounted the feventh 

 Pair, arife from the Middle of the tranvcrie Procelles -of 

 the firil Fertcbra of the Neck ; their Ufe being to nod the 

 Head backwards. 



The lall Pair, called Ohliquiim inferiiis, take their 

 Oi:igih from the Spine or Ridge of the fecond Vertebra 

 of tlji Neck, and forming an oblique Courfe, terminate in 

 the tranfverfe Procelles of the iirii: Vcriebra^ being of Ufe 

 to move the Head femicirculaily. Now the Realbn why 

 there are fo many Mufcles appointed to move the Head 

 backwards, is becaufe of its great Bulk and Weight ; by 

 which Means it is of itfelf prone enough to incline for- 

 ward and downward, fo that it wants not only a Stay, 

 but requireth a greater Force to move it upward oi' back- 

 ward..
