EXAM 2 Flashcards
which vertebra is the anticlerical?
T11
what are the four landmarks for performing and epidural?
ilial wings
S1
Dorsal spinous process of L7
which species tends to have shorter blockier vertebra?
dogs
atlantoaxial sublimation usually occurs due to malformation or hypoplasia of which structure?
dens
which extra ligaments appear on the thoracic vertebrae?
intercapital
where in C1 does the dens articulate?
fovea
what kind of movement does atlas allow?
rotation of the head
where is dens located?
C2
dens is also called?
odontoid process
T/F C1-C2 has an intervertebral disk
F
function of the dens
hold C1 and C2 together
a hypoplastic dens can cause?
-atlantoaxial subluxation
-more movement in that AA joint, C2 can luxate since transverse ligament has nothing to hold onto
fuction of transverse ligament
holds dens in place
function of dorsal atlantoaxial ligament
keeps C1 and C2 in place
what can occur if there was a tear in the dorsal atlantoaxial ligament?
the vertebrae can pop up and pinch the spinal cord, spine of C2 moves up and pinches
spinal intumescence
concentration of lower motor neurons
C6-T2
nerves of brachial plexus
to do a cerebrospinal fluid collection (high tap) where are you going?
cerebellomedullary cistern (cranial to C1)
what is an anatomical characteristic that makes C6 identifiable?
large transverse process
what runs between rib heads from T2-T11?
intercapital ligaments
more support and stability for body
why is the lumbar region of the vertebrae more prone to having issues?
no intercapital ligaments, not very protected or cushioned, the spinal cord is sitting in a very small space so if a disc slips into the intervertebral space can cause neuro deficits
what is the goal of an epidural?
bathe the area surrounding the dura matter
cauda equina syndrome (lumbosacral stenosis)
disc pushing up on the caudal equine (femoral nerve, sciatic, pudendal, pelvic, coccygeal)
L7-S1
screw tail
malformation of one to several vertebrae in the tail
causes skin to form around that malformation and cause infection
