Exam 1 Flashcards
(37 cards)
features of lumbar vertebrae
- larger intervertebral foramen
- more flexion that other motions
- larger body
- drum shaped vertebral body
function of curvatures
force dissipation
number of nerve roots
10 nerve roots
posterior long ligament
runs from axis to sacrum posterior to vertebral bodies
ligament width is consistent
attaches to disc and vertebral rim
supraspinous ligament
ligamentum nuchae to L4 along spinous processes
attaches to disc and vertebral rim
prevents hyperflexion
ligamentum flavum
between outside of inferior lamina and inside of superior lamina
prevents pinching of the synovial plica of fat pad
interspinous ligament
between spinous processes
absent or ruptured often in lower lumbar
prevents segmental hyperflexion
intertransverse ligament
between transverse processes
thick in lumbar spine
restricts side bending
annulus fibrosis
lamina run obliquely to increase stability
thinner posteriorly
sharpey’s fibers
attach rings of annulus fibrosis to vertebral body and endplate
nucleus pulposis
60-70% water interior of disk
highly elastic and semi gelatinous
usual direction of herniation
posterior because annulus fibrosis is thinner and more flexion than extension
T12-L5 area of innervation
anterior and medial muscles of thigh, medial leg, and foot
L2-L4 nerves form
femoral nerve and obturator nerve
lumbar plexus nerve roots
T12 to L4
sacral plexus area of innervation
buttocks, posterior femur, entire lower leg
abdominal wall muscles
rectus abdominus, internal and external oblique, transverse abdominis
muscles for lumbar stabilization
multifidus, quadratus lumborum, erector spinae
history question topics
past medical, present condition, other mandatory questions
past medical history
history of spinal cord
general health
