Atlas
C1, front to back motion of head
Axis
C2, rotatory movement of the head
Vertebral body
Largest vertebral structure, most ventral
Vertebral foramen
Gap surrounded by vertebral body, pedicles, articular processes, lamina
Pedicle
Vertebral structure that connects articular processes to vertebral body
Lamina
Vertebral structure that connects articular processes to spinous processes
Superior articular process
On superior end of vertebrae, between lamina and pedicle
Inferior articular process
On inferior side of vertebrae, between lamina and pedicle
Spinous process
Most dorsal process of vertebrae
Vertebral arch
Includes pedicle and lamina

C7- vertebra promenens T3-in line with spines of scapulae T7- bottom of scapulae T12-last rib L4- in line with illiac crests S2- interspinal plane
Anterior ramus
Spinal nerve, main trunk, innervates trunk and limbs
Posterior ramus
Spinal nerve, smaller branch, innervates skin and back muscles
Posterior rootlets
Small nerves converge to form spinal nerve
Meningeal branch
Branch of spinal nerve that innervates spine itself
Posterior root
Dorsal root ganglia
Sympathetic ganglia
Verically-running ganglia that intersect spinal nerves
