Skull 1-16 Flashcards
Houses incisors AKA - incisive bone
Premaxilae
Front cranial most teeth
Incisors
Behind premaxilla - over canines
Maxillae
“Fang teeth” “cutters”
Canine
Behind canines - grinds food
Premolar
Caudal most teeth - grinds food
Molar
Holes in front of eye orbit CN V lives here along with vessels
Infraorbital foramen
Nose bones - paired down face - gives skull shape
Nasal bone
Whole internal nasal structure
Nasoturbinate
Internal - separates nasal area and brain cavity
Ethmoid
Tiny scrolls of bone in nasal cavity that filter and humidify air
Ethmoturbinates
Creates nasal septum
Perpendicular plate of ethmoid
Internal - ventral to ethmoid, dorsal to hard palate
Vomer
Posterior to maxilla - “hard palate”
Palatine bones
Big pair of holes on ventral surface of skull on the roof of the mouth
Anterior (front) palatine foramen
Front part of the hamulus, articulates with the basisphenoid
Pterygoid process of the palatine
Tiny holes on ventral surface of the skull roof of the mouth
Posterior (rear) palatine foramen
Tear area bone in the anteromedial portion of the eye orbit
Lacrimal bone
“Tear canal” - hole inside eye orbit
Nasolacrimal canal
“Fore head” cranial part of skull
Frontal bones
Protrusion off the top of the orbit behind the eye
Postorbital processes
Internal structure - cavity within the frontal bone - can see when dehorning
Frontal sinus
“Arch” “cheekbone” widest part of the skull
Zygomatic bone (malar)
Front part of the cheek or zygomatic arch
Zygomatic process of the zygomatic bone
Back part of the cheek that articulates with the temporal bone
Zygomatic process of the temporal bone
Caudal to the frontal bone
Parietal bone
Between the parietal and occipital
Interparietal
Runs down the top of the skull
Sagittal crest
Most caudal skull bone to the back of the skull
Occipital bone
Hole that houses the spinal cord
Foramen magnum
Between the tympanic bulla bulbs
Basioccipital
Bumps to the side of the foramen magnum that articulates with C1
Occipital condyles
Big holes by bulbs houses CN IX, X, and XI
Jugular foramen
Tiny holes within the jugular foramen houses CN XII
Hypoglossal canal
Ridge that runs across the skull over occipital
Lambdoidal ridge
Directly below where the sagittal crest meets the lambdoidal ridge
External occipital protuberance
