Axial Skeleton: Term First Flashcards
Parietal Bone
L/R large portions of the skull
Posterior to frontal, anterior to occipital bone
Anterolateral fontanelle
means fountain
at junction of sphenoid, parietal, temporal and frontal bones
Maxilla
upper jaw + roof of mouth + surrounding nose
alveolar process of the mandible
holds teeth in lower jaw
occipital bone
at posterior/inferior portion of skull
spinous process
single process on all vertibrae
points posteriorly
nasal bone
the small part of the nose thats left
above the nose hole
transverse process
lateral pair of processes coming off all vertebrae
coccyx
tail bone
3-5 fused bones
Costal cartilage
connects ribs to sternum
made of thyaline cartilage
temporal bone
large skull portion on lateral side of skull
over the temple
coronal suture
between the frontal and L/R parietal bones
Mastoid process
conical prominance of the temporal bone, located just posterior to the ear
stapes
inner ear bone
means stirrup
zygomatic process of temporal bone
starting at A and leading to B
A- lateral skull segment, over the temple
B- anterior to cheek bone, lateral to eye
lacrimal bone
bone in eye socket
anterior in socket
just lateral to nasal bone
intervertebral disk
seperates/cushons the vertebrae
costal
referring to ribs
occipital condyles
outcroppings of the back/low skull
just above top vertebrae
alveolar process of the maxilla
holds teeth in upper jaw
styloid process
thin prominance of the temporal bone sits just inferior to the external acoustic meatus
looks like a styletto
palatine bone
posterior hard palate
condyle
means knuckle
large round protuberance at the end of a bone
crista galli
superior most part of ethmoid bone
anterior/inferior of brain cavity
stylomastoid foramen
hole inbetween the styloid and mastoid processes
foramin magnum
foramen in the skull
spinal chord goes through this
zygomatic bone
means yolk- referring to a pair
lateral to eyes
anterior of the cheek bone
coronoid process of the mandible
means “like a beak”
sharper tip of the ramus
frontal bone
forhead, ranging back to the parietal bones
zygomatic arch
spans between the cheek bone and the temple
meatus
tube-like opening
means passageway
mandibular foramen
on the inside surface of lower jaw, right behind molars
body of vertebrae
main portion on anterior of all vertebrae
vertebral foramen
spinal cord passes through this vertebral part
body (of sternum)
middle 80% of the sternum
manubrium
superior-most part of the sternum
looks a bit like a condyle
sella turcica
turkish saddle
middle of the sphenoid bone
Posterolateral fontanelle
means fountain
at junction of temporal, occipital, and parietal bones
superior/middle nasal concha
part of the ethmoid bone
lateral, middle/superior outcroppings inside the nose
Temporal process of zygomatic bone
posterior cheek bone -> temple
xiphoid process
posterior tip of sternum
external acoustic meatus
external ear hole
squamous suture
suture between the temporal and parietal bones
