Cat Flashcards
large bone that makes up posterodorsal part of brain case
parietal
on either side of the skull, dorsal to the posterior teeth, house eyeballs
orbits
cranial wall posterior to each orbit
temporal fossa
vantral margin of orbit and fossa
zygomatic arch
opening and passageway to inner/middle ear
external auditory meatus
hole in posterior surface of the skull through which spinal cord connects to brain
foramen magnum
flat region between teeth on ventral side of skull
hard palate
two openings of nasal passage in live cat
choanae
paired oval and convex regions on posteroventral side of skull
tympanic bulla
most anterior paired bones of the skull, form dorsal margins of naris
nasal
posterior to nasals, contribute to lateral and dorsal surfaces of skull, most of orbital walls
frontal
projects ventrally from each frontal to demarcate posterior region of orbit
postorbital process
large bones forming most of the dorsal and lateral parts of the cranium
parietal
small bone wedged between posterior ends of parietals
interparietal
converging point of temporal lines on posterior of parietal/interparietal
sagittal crest
bone that froms skull’s posterior surface
occipital
features of occipital bone that articulate with first vertebra
occipital condyles
on ventral cranium just posterior to tympanic bulla
jugular process
bones that form lateral and ventral margins of nasal aperture
premaxilla
larger bones that hold majority of teeth and form most of hard palate in ventral view
maxilla
snout, where maxilla, premaxilla, nasal, and frontal bones meet
rostrum
small bone on the anterior orbital wall
lacrimal
bones that complete the hard palate posteriorly
palatine
extension of palatine that extends posteriorly
pterygoid
elongated, median, narrow bone lying between pterygoid blades
presphenoid
lateral extension of pre sphenoid that is exposed in ventral orbital wall
orbitosphenoid
posterior end of the palatine bones in almost centre of ventral surface
basisphenoid
lateral, winglike portion of sphenoid
alisphenoid
most anterior foramen, lies entirely within orbitosphenoid
optic canal
second foramen formed by orbitosphenoid and alisphenoid
orbital fissure
third foramen, in alisphenoid
foramen rotundum
fourth foramen, in alisphenoid
foramen ovale
extends anteriorly from pre sphenoid in nasal cavity
vomer
foramina piercing cribriform plate
cribriform foramina
squamous, petrous, and tympanic fused together
temporal
large flat bones ventral to the parietals that help to complete the lateral wall of the braincase
squamosal
petrous portion of temporal, contains inner ear, may be seen through external auditory meatus
petrosal
tiny bones of middle ear
malleus, incus, stapes
single bone that forms each side of mandible
dentary
largest process of mandible, point of insertion for temporal muscle
coronoid process
