ANATOMICAL TECHNOLOGY. 



Fm. sphplt., Foramen spheno-palatinum. — Spheno-palatine foramen. 

 Fm. infor.. Foramen infraorbitale. — Infraorbital foramen. 



§ 554. Lm. (Lamina) cribrosa — Cribriform plate of the ethmoid. — The mesetlimoid 

 separates the bones of the two sides. The cribriform plate is the cranial part of the eth- 

 moid, the ethmo-turbinals properly belonging to the face. 



O. praesph., Os praesphenoideum, az. — , 

 Praesphenoid bone. 



O. pit., Os palatinum. — Palate bone. 

 O. Ich., Os lachrymale. — Lachrymal 

 one (Fig. 56). 

 O. planum (Fig. 56). 



O. ethtrb., Os ethmo-turbinale — Eth- 

 mo-turbinal bone. — In this figure is shown 

 the rounded scroll-like part projecting into 

 the frontal sinus (§ 550). 



O. frontis. — Frontal bone. 



Sinus frontalis. — Frontal sinus (Fig. 56).

§ 555. Fig. 61 — Preparation. — 

 After the removal of the soft parts 

 (§ 250, B), the rami were separated 

 at the symphysis menti (Fig. 62). 



§ 556. An. (Angulus) mandibularis.- 

 Mandibular angle. 



Cd. mndb., Condylus mandibularis.- 

 The condyle or arthral head of the mandible (Fig. 62). 



D. m., Dens molaris. — Molar tooth. 



DD. pm., Dentes praemolares — Praemolar teeth. — The bicnspidea of Anthropotomy. 



D. c. Dens caninus. — Canine 

 tooth. 



DD. i., Dentes incisores. — 

 Incisor teeth. 



Fm. m., Foramen mentale — 

 Mental or labial foramen. — There 

 are almost invariably two on each 

 Bide in the cat. 



Fs. (Fossa) coronoidea — Cor- 

 onoid fossa. — From this fossa arises 

 a large part of the masseter muscle. 



Pre. cor., Processus coronoi- 

 deus. — Coronoid process. 



§ 557. Ramus, Ramus mandibularis — Mandibular ramus. — The mandible is made 

 Tip of two similar bones joined at the symphysis menti, and these rami form the frame- 

 work of the floor of the mouth ; Flower, A, 120. 



In Human Anatomy, the " ramus " is the so called " ascending part," and not the 

 entire half of the mandible as here ; Quain, A, I, 54.
