Document Summary
Normal curvatures: born with one big curvature, secondary curvatures form in babies, third forms at about 4 years old. Scoliosis: side to side curvature, both lateral curvature and rotation of the vertebra. Lordosis: increased lordotic curvature (lower back curves too far forward) General vertebrate structure: without folic acid lamina doesn"t develop, causing spinal bi da, spinous process: what we feel when we touch our spine, vertebral foramen: spinal cord sits within, superior articular facet articulate with articular processes of vertebra above. Cervical spine: transverse foramen: holes inside transverse process, passage of vertebral arteries going to brain, bi d spinous process, axis and atlas, atlas c1: no body(facet for dens), no disk, occipital condyles, axis c2: body=odontoid process, no disk. Thoracic spine: less movement than cervical and lumbar, costal (rib) facets on body, facets: t1,t10, t11, t12, demifacets: t2-t9 (sharing a rib with two vertebras, facet of transverse process, long, slender spinous process.
