Document Summary

The vertebrae column: vertebrae has the ability to protect the central nervous system (spinal cord) Anterior aspect: seems like a stable structures, everything is stacked nicely and sturdy: | Lateral aspect: unstable, bones are meant for stability and support, but there are areas of instability, but they are designed for movement. Superior --> inferior: the spine: numbered in sequence, you can feel c7 on the back of your neck. The (cid:272)ur(cid:448)atures are i(cid:373)porta(cid:374)t, (cid:271)e(cid:272)ause they (cid:272)a(cid:374) : primary curvatures = exist at birth (thoracic, sacral coccyx, secondary curvatures = occur after birth (cervical/lumbar), the cervical curvature occurs when the baby can hold their own head up straight. The muscles aren"t strong e(cid:374)ough, so the (cid:272)ur(cid:448)ature has(cid:374)"t for(cid:373)ed yet. lumbar = develops when you start walking, the muscles will start to strengthen and form this curvature. Exaggeration of the lumbar = lordosis, something that can develop over time, obesity can cause this.
