The quadratus lumborum is implicated in the formation of which ligament?
the iliolumbar ligment
What will innervate the quadratus lumborum?
the ventral rami of T12 & L1-L3 or L4 spinal nerves
What is the origin of the psoas major?
vertebral bodies T12, L1-L5, S1 transverse processes of L1-L5
What is the origin of the psoas minor?
vertebral bodies T12, L1
What will innervate the psoas minor?
the ventral ramus of L1 spinal nerve

the dorsal rami of T1-T12 spinal nerves
What will innervate the levator costarum longus?
the dorsal rami of the lower thoracic spinal nerves
What will innervate the serratus posterior superior?
the ventral rami of T2-T5 spinal nerves…intercostal nerves
What will innervate the serratus posterior inferior?
the ventral rami of T9-T11, the intercostal nerves &
the ventral ramus of T12, the subcostal nerve
What is the maximum number of common ligaments identified with the vertebral couple?
eight
What is the resin that nine common ligaments are identified but only eight will be attached at any specific vertebral couple?
the ligamentum nuchae and supraspinous ligaments attach to the spinous tubercles, but only one of these will be identified at a single vertebral couple
What is the number of true intervertebral discs identified in the adult?
twenty-three
What is the percent of intervertebral disc height contribution to the length of each region of the vertebral column?
cervical…22-25%; thoracic…20%; lumbar…33%
What is the cervical nucleus pulposus composed of?
fibrocartilage
What is the water concentration in the lumbar nucleus pulpous at birth and after thirty?
birth….88%; thirty…70%
What is the organizational pattern for glycosaminoglycans in the lumbar nucleus pulposus?
they typically lack a binding site for hyaluronic acid and are thus non-aggregated
What cell is associated with the nucleus pulposus until about age eleven?
notochord cells
Which type of collagen is dominant in the nucleus pulposus?
collagen type II
