what are 1 degree curves
kyphoses
What vertebral pair doesnt have a vertebral disc
C1-C2 and sacral vertebre
when a nucleus pulposus herniates which way does it go and why
laterally, deflected by the posterior longitudinal ligament
myotome
muscle fibers supplied by a single spinal nerve
dermatome
sensory region of skin supplied by spinal nerve
what divides the anterior and posterior roots within the dural sheath
denticulate ligament
what happens if the intervertebral canal closes
the spinal nerves become impinged
radicular pain
usually caused by herniate nucleus pulposus or narrowing of the intervertebral foramen sensory/motor pain that radiates ALONG A DERMATOME (that’s the important part)
nonradicular pain
is ONLY in the back and/or gluteal area without radiation into the lower limbs. this is caused by NON NERVE INJURIES (muscle/tendon strain, ligament sprain, arthritis fractures ect.)
Herniated nucelus pulposus lumbar region
affects the spinal nerve at the level below it
herniated nucleus pulposus cervical region
affects nerve exiting at the same level but since there are eigth spinal nerves the numbers still coincide (ex. HNP between C6-7 would affect C7 nerve.)
rotation and side bending with compression
spurlings
push down on head
compression
pull up on chin
distraction test
straight leg raising
put pt in supine and raise complaint leg, if positive pain, try non complaint leg. if still positive then lumbosacral is problem
What acts as aponeurosis for latismus dorsi and serratus posterior inferior muscles
thoracollumbar fascia
What swells and causes headaches
myodural bridge
what is included in standing posture (back only)
erector spinae, multifundus, semispinalis
what tears during cervical hyperflexion
interspinous ligament
