Lumbar Flashcards
main fxns of lumbar spine
protect spinal cord
F/E mostly, also R/S
support upper body
structures w/ pain sensing
anterior longitudinal ligament annulus posterior longitudinal ligament vertebral body supraspinous ligament zygapophyseal joint
lumbar vertebrae anatomy
large bodies
SP and TP are flat
articular facets oriented vertically
nerve roots ext foramen below corresponding vertebrae
caude equine
collection of nerve roots
L2 - S5
anterior longitudinal ligament
along ant of vert bodies
limits extension
posterior longitudinal ligamnet
along post of vert bodies
ant to spinal cord in spinal canal
thin
limits flexion (more flexible)
intervertebral discs
separate vertebrae
annulus fibrosis + nucleus pulposus
ligamentum flavum
post wall of spinal canal
btwn lamina of subsequent vertebrae
interspinous ligaments
btwn consecutive spinous processes
supraspinous ligament
most post lig
run over pot edge of SPs
intertransverse ligaments
connects TPs of vertebrae
thoracolumbar fascia
broad CT
mainly encompass latissimus dorsi
O: sacrum
I: occiput
iliocostalis lumborum (O/I/N/A)
O: sacrum, iliac crest, thoracolumbar fascia
I: rib 6-12, thoracolumbar, upper lumbar TP
N: spinal C8-L1
A: (u) spine ST (b) extends spine
longissimus thoracis (O/I/N/A)
O: sacrum, iliac crest, lumbar SP, lower thoracic TP
I: rib 2-12, lumbar costal processes, thoracic TPs
N: spinal C1-L5
A: (u) spine ST (b) extends spine
spinalis thoracis (O/I/N/A)
O: T10-L3 SP
I:T2-T8 SP
N: spinal n
A: (u) cervical and thoracics ST (b) extend cervicals and thoracics
multifidus
O: C2-sacrum
I: same as O
N: spinal n
A: (u) flex spine same side, RA (b) extend spine
interspinales lumborum

intertransversii laterals lumborum
O: L1-L5
I: same
N: spinal n
A: (u) lumbar ST (b) extend lumbar
fryette’s law
