The second is term'd Styloglossus, its Rise being in the Apophysis Styloides, from whence it passeth to the side above the Tongue, to lift it up.
The third bearing the Name of Basiglossus, commenceth in the Basis or Root of the Os Hyoides, and thence insinuates it self into the Root of the Tongue, to draw it back to the bottom of the Mouth.
The fourth is the Ceratoglossus, deriving its Original from the Horn of the Os Hyoides, and cleaving to the side of the Tongue to draw it on one side: The Action of these Muscles of both sides together, causeth an Orbicular Motion in the Tongue. To these some add a fifth
Pair of Muscles, call'd Myloglossus, which serves to draw it obliquely upward.
What is the Action of the Os Hyoides in the Throat, and how many Muscles hath it?
The use of the Os Hyoides is to consolidate the Root of the Tongue; and it hath five Muscles on each side, which keep it as it were hung up.
The first of these, call'd the Geniohyoideus hath its beginning in the Chin on the inside, and adheres to the top of the Os Hyoides, which it draws upward.
The second is the Mylohyoideus, whose Origine is in the inner side of the Jaw, from whence it cleaves side-ways to the Root of the Os Hyoides, which it draws upward, and to one side.
The third is the Stylohyoideus, which after it hath taken its rise in the Apophysis Styloides, is fasten'd to the Horn of the Os Hyoides, to draw it toward the side.
The fourth is the Coracohyoideus, which springing up from the Apophysis Coracoides of the Omoplata, cleaves to the Root and side of the Os Hyoides, to draw it downward and to the side.
