Section 1

Question Answer
primary curvature where and whenthoracic and sacral, in fetus
secondary curvature where and whencervical and lumbar, during infancy
Kyphosisincreased thoracic curvature usually resulting from osteoporosis
Lordosisincreased lumbar curvature due to weakened abdominal muscles - often associated with pregnancy or obesity
Scoliosisabnormal lateral curvature of the spine; 80% of unknown origin, 20% asymmetrical weakness of back muscles (muscle dystrophy)
memorize

Section 2

Question Answer
ligamentum flavumruns from 1 spine to another; support vertebral column
interspinous ligamentruns from 1 spine to another; support vertebral column (like b/w spinous processes)
posterior longitudinal ligamentrun posterior part of vertebrae column like a cylinder cord (runs along length of spinal cord)
anterior longitudinal ligamentruns all anterior face of vertebrae column and face thoracic structures
intervertebral discbetween vertebrae, acts as shock absorber so it is not bone to bone; has anulus fibrosus and nucleus pulposus
herniated intervertebral discanulus fibrosus gets ruptured and nucleus pulposus spills out & intrude vertebral canal & presses onto spinal cord/nerves -> pain
memorize

Section 3

Question Answer
inferior articulate process + superior articulate process forms the zygapophysial joint
Is there movement of flexion at C1 and C2?No, if you flex, would push dens into spinal cord; does allow rotation around dens axis to say NO
C1 movementsuperior articulate facet articulate with occipital condyle so allow movement of head to say YES
which vertebrae has foramen transversanium?cervical vertebrae, vertebral artery travels through (transverse process is a hole whereas thoracic articulate w/ ribs and lumbar is just transverse process)
the 7th rib articulate with what?7th rib articulate with transverse process of T7, and superior facet of T7, inferior facet of body of T6 (ONLY IN THORACIC DO YOU HAVE RIBS)
auricular surfacewhere sacral articulate with hip bone to form hip joint
cervical superior facets and inferior facets orientationsuperior facet - superoposteriorly; inferior facets directed inferoanteriorly (horizontal)
thoracic superior facets and inferior facets orientationsuperior facets directed posteriorly; inferior facets directed anteriorly
lumbar superior facets and inferior facets orientationsuperior facets directed medially; inferior facets directed laterally
which vertebrae has bifid spinous processcervical vertebrae
which vertebrae has triangular vertebral foramencervical vertebrae & lumbar
which vertebrae has spinous process that is long and slopingthoracic vertebrae (think of it as to balance out for the rib cage)
which vertebrae has short, blunt spinous processlumbar vertebrae
which has smallest vertebral foramenthoracic vertebrae (the only one not triangular)
