26 bones: vertebrae (24, sacrum (1, coccyx (1) approximately 70 cm long in average adult consists of five regions, cervical (7 vertebrae, thoracic (12 vertebrae, lumbar (5 vertebrae, sacral, coccygeal spinal curvatures, primary: thoracic sacral, secondary: cervical lumbar. Lordosis: also called swayback, the spine of a person with lordosis curves significantly inward at the lower back, extenuated lumbar curvature, you get this when you"re pregnant. Kyphosis: kyphosis is characterized by an abnormally rounded upper back (hunchback), exaggerated thoracic curvature. Scoliosis: a person with scoliosis has a sideways curve to their spine. Point of attachment of a lot of muscles in the back, which is responsible for keeping normal alignment: transverse process articular processes, superior, inferior, articular facets vertebral foramen (canal) intervertebral foramina regional vertebral characteristics: cervical vertebrae: C1 and c2 are atypical: altlas, axis. C3-c7 are typical: oval body, bifid spinous processes (except c7, large triangular vertebral foramen, transverse foramen, c7 is the vertebral prominens thoracic vertebrae:
