Document Summary

* the vertebral column axial skeleton (what everything else hangs off) 12 thoracic vertebra (ribs come off here for most people), 5 lumbar vertebra, 5 fused sacrum vertebra & 3-4 fused coccyx vertebra/vestigial tail) Movement there are sets of joints between adjacent vertebra and these joints are involved in permitting & limiting movement. Protection of the nervous system spinal cord running inside. * se(cid:272)o(cid:374)dar(cid:455) (cid:862)lordoti(cid:272)(cid:863) (cid:272)ur(cid:448)es de(cid:448)elop i(cid:374) (cid:272)er(cid:448)i(cid:272)al/neck (in order to look around) and lumbar (enables us to stand on two feet/enables bipedal locomotion) regions. * primary curve persists in thoracic region and also the fused sacral vertebra. * abnormal curvatures may occur: kyphosis (increased primary curve of the thoracic region - hunchback), scoliosis (vertebra with slight lateral deviation), abnormal lordosis (pulls lumbar spine into a more lordotic curve e. g. pregnant woman) * vertebra consist of two parts the vertebral body (anteriorally) & the vertebral arch (or neural arch)
