CHAP. XII. Of the Tongue.
THE tongue is of a fleshy, rare, loose and soft substance; it enjoyes flesh * 1.1 of a different kind from the rest of the flesh, as chiefly appeares when you cut it from the first originall of the muscles thereof; which thing hath moved some, that they have made a fourth kind of flesh proper to the tongue and different from the rest, viz. the Fibrous, musculous, and that of the bowells. The quantity thereof is such that it may be conteined in the mouth, and * 1.2 easily moved to each part thereof. The figure of it is triangular, which it rather ex∣presses * 1.3 in the basis, which is at the root of the bone Hyoides, than in its point, or forepart, where from a triangle it becomes more dilated. It is composed of a mem∣brane * 1.4 (which it hath from that which lines all the inside of the mouth) muscles 4. nerves two on each side, the one whereof is sent from the third conjugation, into the coate thereof; the other from the seaventh is sent into the musculous substance * 1.5 even to the end thereof for motions sake; so that those sensificke nerves from the third conjugation onely give to judge of tastes, compose the coate, and touch or enter not the flesh. Besides it is composed of veines and arteries on each side one, which it receives from the externall Iugular and Carotides, running manifestly to the end thereof on the lower side, that so they might be easily opened in the di∣seases of the mouth and throtle; they commonly terme these the Vena nigra or blacke veines.
The muscles of the tongue are absolutly ten, on each side five. The first narrow at the beginning, and broader at the end, descends into the upper side of the tongue * 1.6 from the Appendix Styloides, and together with its copartner drawes it upwards. The second hath its originall within from the lower jaw about the region of the Grindinge teeth, and is inserted into the lower side of the tongue, the which with its partner drawes it downeward. The third proceeds from the inner part of the Chin and goes to the root of the tongue, that when need requires it may put it forth of the mouth. The fourth the greatest and broadest of them all, composed
