vertebral regions

- cervical (7)
- thoracic (12)
- lumbar (5)
- sacral (1 - 5 fused)
- cocyx (1 - ~4 fused)

2

parts that make up individual vertebrae

spinous process
transverse processess
body
vertebral foramen
pedicles
laminae

3

spinous process

projects dorsally on posterior side

4

transverse processes

project laterally

5

vertebral foramen

surrounds spinal cord

6

pedicles

connect body to transverse processes

7

laminae

forms the "roof", connects transverse processes with spinous process

8

intervertebral foramina

between pedicles of adjacent vertebrae, for nerve connections to spinal cord

9

intervertebral discs

pads of fibrous cartilage that separate the vertebral bodies, absorbs shock

10

atlas

1st cervical vertebra (C1), allows you to nod your head 'yes'
- no body or spinous process
- articulates with dens of axis

11

axis

2nd cervical vertebra (C2), allows you to nod your head 'no'
- dens: projection that the atlas rotates around

description of cervical vertebrae

body - small, rectangular
spinous process - short, may be split
transverse processes - has foramina (holes)
