Styloceratohyoides.
THis third pair ariseth from the Root of the Processus Styloides,* 1.1 and being small and round, is implanted into the Horn of the Os Hyoides, found infallibly by Di∣gastricus his running through or under him, obliquely, moving the Os Hyoides obliquely upwards.
This draws it obliquely upwards.* 1.2
Observe that its Insertion is in the lower part of the Horn (or rather towards the Basis) of the Os Hyoides.
E. E. Shews this, Tab. 8. Fig. 3. F. F. Shews the same, ead. Tab. Fig. 2.
Amongst these Muscles of the Fauces,* 1.3 the two pair lately found out by the Ingenious Doctor Croune may not im∣properly here be mentioned; one of which are named by him Musculi Pterygo-palatini, and the other Spheno-palatini. The former of these are seated in the Interior part of the Cavity of the Os Pterygoides, and terminate with their Tendons (which run on part of the foremention'd Bone as on a Trochlea) about the Glandula palati, which (together with the Uvula) they depress.
The latter of these, or Spheno-palatini, arise from the Os Sphenoides, and with a broader Tendon are inserted into the sides of the Glandula palati, which (together with the Uvula) they do attoll. From the situation and action of these latter Muscles may some account be given, how the Uvula being relaxt is com∣monly reduc't by thrusting the Thumb bent toward the Palate or these Muscles.
These Muscles you have exactly shewn you at Tab. 10. Fig. 2. at O. O. X. X. Shews its Tendon, Q. Shews the latter, where f. f. shews its Tendon also.
