Document Summary

Chapter 9 the spinal column and thorax. Curves of the spine: normal posture-plumb line. 7 cervical vertebrae: c1 to c7 and 8 nerve roots: c1-c8. Oa (occiput and atlas or atlanto-occipital joint) and the aa or atlanto-axial joint. Lordosis is assisted by wedge shaped discs, like lumbar discs, which are larger anteriorly. Tmj relationship with cervical spine upper: c1-2 middle:c3-5 lower: c6-t1-2. Joint of luschka (bad) : not good spacing string lines up with: knee, hip, external auditory meatus superior angle lines up with t2. O-a-a joints make up 40% of cervical flexion and 60% cervical rotation. Atlas has concave masses that join with convex occipital condyles: flexion and. Stability in cervical spine especially within o-a-a complex is articulation and ligamentous laminectomy: shaving down lamina. Viscoelastic material allowing it to sustain great loads when they are rapidly. Discs: contribute to 1/3 height of spine disc is made up of water (this is how we get shorter)
