Q

All Cervical Vertebrae:

transverse foramen

bifid spinous process

A

on each transverse process; for vertebral artery, veins, and nerves of the vertebral plexus

split at its posterior extent (except for C1/atlas and C7)

Q

The Atlas (C1 Vertebra):

anterior arch with anterior tubercle

facet for dens of axis

lateral mass

posterior arch with posterior tubercle

groove for vertebral artery and first cervical nerve

A

no vertebral body (centrum) on the atlas

posterior aspect of anterior arch(pivot type of synovial joint)

contains superior articular facet (atlanto-occipital joint, an ellipsoid type of synovial joint) and inferior articular facet(plane type of synovial joint)

(remnant of the spinous process)

superior aspect of posterior arch, just posterior to lateral mass

17
Q

The Axis (C2 Vertebra):

dens/odontoid process

A

cranially projecting process on superior/cranial aspect of vertebral body that allows rotation of the axis(atlantoaxial joint, a pivot type of synovial joint)

18
Q

The Typical Cervical Vertebra, C3–C7:
uncinate process or uncus

anterior and posterior tubercles of the transverse process

intertubercular lamella of transverse process

A

lateral lip on superior vertebral body; resists lateral displacement

Left and right

lateral; between the two tubercles of the transverse process
