There are fourteen, _viz._ four Common, and ten Proper. The first Pair of the Common is the _Sternothyroideus_ or _Bronchycus_, which proceeding from the inside, and the top of the _Sternum_, ascends along the Cartilages of the Wind-Pipe, and is terminated in the bottom of the {29} _Scutiformis_ or Buckler-like Cartilage, which it draws downward. The second is the _Hyothyroideus_, which ariseth from the Root of the _Os Hyoides_, and is inserted in that of the _Scutiforme_. This Muscle serves to lift up the _Larynx_, as also to dilate the bottom of the _Scutiformis_, and to close its top. The first Pair of the Proper is the _Cricothyroideus Anticus_, which deriving its Original from the hinder and upper part of the _Cricoides_, or Ring-like Cartilage, is fixt in the upper and lateral part of the _Scutiformis_, to close or shut it up. The second is the _Thyroides_. The third is the _Cricoarytenoideus Lateralis_, which proceeds from the side of the _Cricoides_ within, and is fasten'd to the bottom and side of the _Arytenoides_, which it removes to dilate the Mouth of the _Larynx_. The fourth is the _Thyroarytenoideus_, which arising from the fore-part on the inside of the _Scutiformis_, is terminated on the side of the _Arytenoides_, to close the Orifice of the _Larynx_. The fifth is the _Arytenoideus_, which having its Source in that place where the _Cricoides_ is united to the _Arytenoides_ is inserted in its upper and lateral part, to close the _Larynx_. _How many Muscles hath the _Pharynx_?_ It hath seven, the first whereof is the _Oesophagieus_, which takes its rise from the side of the _Scutiformis_ or Buckler-like Cartilage, and passing behind the _Oesophagus_ or Gullet, is fasten'd to the other side of the Cartilage. It thrusts the Meat down by locking up the _Pharynx_ as a _Sphincter_. The second named _Stylopharingæus_, springs from within the Acute _Apophysis_ of the _Os Sphenoides_, or _Cuneiforme_, and is inserted obliquely {30} in the side of the _Pharynx_, which it dilates by drawing it upward. The third, call'd _Sphenopharyngæus_, proceeds from the _Apophysis Styliformis_, and is terminated in the side of the _Pharynx_, which it dilates by drawing its sides. The fourth Pair is the _Cephalopharyngæus_ which ariseth from the articulation of the Head with the first _Vertebra_, and closeth the _Larynx_. _How many Muscles are there in the Neck, and which be they?_ There are four Muscles in the Neck on each side, _viz._ two Flexors, and two Extensors. The _Flexors_ are the _Scalenus_ and the _Rectus_ or _Longus_; and the Extenders are the _Spinatus_ and the _Transversalis_. The _Scalenus_ or _Triangularis_ hath two remote Sources, _viz._ one in the first Rib, and the other in the Clavicle, and is fasten'd to the third and fourth _Vertebra_ of the Neck.
