another name for apophyseal joints facet joints
main load bearing component of the lumbar spine Interbody joint
load bearing of the interbody joints 80%
the apophyseal joints are articulations of the superior and inferior articular processes
what portion of the vertebrae increase the leverage of muscles and ligaments transverse and spinous processes
interbody joints articulate by way of? intervertebral discs
two components of the Intervertebral disc Nucleus Pulposus Annulus Fibrosus
The nucleus pulposus resists what type of forces compressive (flattening) tensile (expansion)
The annulus fibrosus resists what type of forces compressive (flattening) torsional (???) tensile (???)
a lumbar stress fracture occurs where? pars interarticularis
