Acb lecture 20 axial skeleton: vertebral column. Text(cid:9)page(cid:9)171,(cid:9)180-182: look at lateral view of spine can see its curved, curves allow for compression and a little bit more movement, looking at differences as we grow old. Scoliosis abnormal(cid:9)lateral(cid:9)curvature(cid:9)of(cid:9)the(cid:9)spine: 80%(cid:9)idiopathic, other(cid:9)causes(cid:9)include(cid:9)asymmetrical(cid:9)weakness(cid:9)of(cid:9) back(cid:9)muscles(cid:9)or(cid:9)incomplete(cid:9)formation(cid:9)of(cid:9)vertebrae, posterior view. )diopathic = we don"t know what causes this.

Anterior: processes are things that stick out, all 3 of these are sights for muscle attachment and movement. Vertebral arch forms this opening a foramen where spinal cord passes through: at each level of the spinal cord we have these typical features as well as some modifications vertebral column depending on where they are. Anterior: lamina is attached to the pedicle (feet that are attached to the body) together they form the vertebral foramen.
