iRA/tRA #1 Flashcards
most prominent spinous process
C7
typical cervical vertebrae
C3-C7
uncinate process has what shape
saddle
C1 is also called
atlas
anterior arch
posterior surface articulates with dens from C2
anterior tubercle
posterior arch
groove for VA
posterior tubercle
what attaches at posterior tubercle
ligamenta flava
2 surfaces of lateral masses
superior surface– kidney shaped
inferior surface– circular, concave M/L and convex A/P
where can you palpate the transverse processes of C1
between mastoid process and ramus of mandible
C2 is also called
axis
2 facets of the articular pillars
superior– convex
inferior– oriented inferior and anteriorly
what is the groove in pedicles of C2 for
vertebral artery
odontoid process (dens) function
axle for head rotation
articular facet for articulation with anterior arch of C1
stabilizing ligamentous structures of dens
transverse ligament
apical ligament
alar ligament
IV discs are composed of
nucleus pulposus
annulus fibrosis
vertebral endplate
layers of vertebral endplate
hyaline cartilage– towards vertebral body
fibrocartilage– towards nuclues
vertebral endplate is encircled by
ring apophasis
anterior annulus
thick, strong
lambdoid orientation
joins near midline
posterior annulus
thin
longitudinal fibers
transverse fissure to allow for swinging motion of vertebral bodies
function of zygapophysial joints
guide and limit movement of spine
zygapophysial joint is a _____ joint
synovial
fibroadipose meniscoid
highly innervated structure
encloses fat, collagen, and blood vessels
what do fibroadipose meniscoids protect
articular cartilage that would otherwise be exposed during motion
articulating surfaces of joints of luschka
medial border of uncinate processes and inferiolateral border of the superior vertebra
