Document Summary

Anatomy 215 (reading materials: chapter 6: pages 164-176; chapter 8: pages 220-222; chapter 10: pages 281-284; chapter 22: pages 587, 593, 595) C1 and c2 are atypical: atlas (c1)- ring of bone with 2 large articular surfaces, skull makes contact with occipital axis (c2)- knob/ bony projection= dens, odontoid process, pivot point for atlas to move condyles. C3-c7 are typical: oval body bifid spinous processes (except c7)- split spinous process, c3-c6 large triangular vertebral foramen transverse foramen- hole in transverse process, major blood vessels- on side of neck, supply brain. C7 is the vertebral prominens- bump on neck thoracic vertebrae: T1-t12 articulation with ribs: facets and demifacets heart shaped body- articulating facets for the ribs facet orientation between vertebral arches is coronal circular vertebral foramen long spinous process that points downward lumbar vertebrae: Lumbar vertebrae: facet joints (intervertebral between superior and inferior articular processes)- plane type of synovial. Articulation: intervertebral discs-fibrocartilage, connects body of vertebrae joint.
