thoracic anatomy Flashcards
cells that migrate anteriorly in the somatic nervous system give rise to muscles of the limbs and trunk
hypaxial muscles
cells that migrate posteriorly from somatic nervous system give rise to intrinsic back muscles
epaxial muscles
cervical facet
45 degree angle
thoracic facet
coronal plane
lumbar facet
sagittal plane
anticlinal vertebrae
canine - T11
equine - T15
spinal cord equine ends at
S2
canine spinal cord ends at
L6/7 disc
feline spinal cord ends at
sacrum (L6-S3
synovial joint between TP of L6 and wings of sacrum
intertransverse joints equine
serve to maximize stability in the region
slight cranial concave and convex caudal surfaces
tight joint capsule and joint may fuse in adult horse
intertransverse joints in equine
rupture and or overstretch of this ligament due to over extension results in calcium deposits and subsequent spondylosis
ventral longitudinal ligament
1 site for herniated IVD in the dog
thoracolumbar transition zone
supraspinatus m.
C6-7 (6)
Axillary nerve
C6-8 (6)
musculocutaneous n.
C6-8 (7)
radial nerve
C7-T1
extensor muscles of the elbow carpus and digits
radial nerve
skin of the dorsal surface of forearm and paw
radial n
damage to raidal nerve proximal to origin of triceps and dog
cannot bear weight on limb, knuckling of paw
distal injuries, most dogs can compensate by flipping paw forward so
it lands on the pads - radial n
decreased triceps reflex
radial n.
median and ulnar nerves
C7-T1 (C8-T1)
brachiocephalicus
C6-7 (C6)
