Document Summary
Curvatures of the vertebral column: primary degree of curvatures in fetus: thoracic and sacral, secondary degree of curvatures develop during infancy: cervical and lumbar. Not straight: has curved which allow for compression and movement: need resilience while walking: a little bit of bounce as we walk, help absorb forces. Different development as we require and develop, secondary curvatures develop as we progress: In the fetus: primary curvature, one continuous c shape: when baby starts to hold head up: cervical region develops, when baby starts to walk: lumbar region. Some permanent and some transient: last forever or not. Abnormal curvature of the vertebral column: scoliosis from the posterior view. Scoliosis abnormal lateral curvature of the spine: 80% idiopathic do not know why occurs. !other causes include asymmetrical weakness of back muscles or incomplete formation of vertebrae. Look at specific angles to determine the severity.
