PREVENTS HYPERFLEXION
ALL
most commonly torn in whiplash; dens is also commonly fractured
PREVENTS HYPEREXTENSION
muscle attachment for glut max and pelvic diaphragm; non weight bearing
Sacral promontory: anterior aspect of S1; obstetric landmark
Sacral foramina: ventral and dorsal primary rami from S1 to S5 nerves
Sacral canal: transmits cauda equina (L1 to Co1)
Mammillary processes: superior articular process
Accessory processes: base of Trans process
Costiform processes: at tip of transverse process
Largest (specifically L5): support body weight
Demifacets for articulation with head of ribs
Costal facets on transverse processes: transverse facet; articulate with tubercle of rib
Costal facets on centrum: superior and inferior; articulate with head of rib
C7: vertebral foramen contains a vein, forms the vertebra prominens
ALL (C1-C7): large vertebral foramen due to cervical enlargement, transverse foramen containing vertebral artery
C2-C6: BIFID
Typical
C3-C7
Atypical
C2: Axis
Dens/Odontoid process
C1: Atlas
articulation surface for Dens from C2
Anterior and posterior masses
articulates superiorly with occipital bone of skull at Articular Facets
No spinous process
No body
Openings
Intervertebral foramen formed by Vertebral notches (superior and inferior): where spinal nerves will exit
Vertebral foramen (canal): formed by arch, spinal cord passes through here
Vertebral Body (Centrum)
Vertebral arch: formed by lamma (most posterior) and pedicle (lateral borders of arch)
Articular Processes (facets): superior and inferior
