11. spinal column (26 bones)- body, pedicles, lamina, spinal
process, transverse process, Spinal foramen, inferior articulating
process, superior articulating process

12. • The cervical vertebrae are the first (upper seven)
vertebrae. Foramen in each transverse process for
transmission of vertebral artery, vein and plexus of
nerves; short bifurcated spinous processes except on
seventh vertebra, where it is extra-long and may be felt
as protrusion when head is bent forward; bodies of these
vertebrae are small , whereas spinal foramina are large
and triangular. (1)
• Atlas- is the first cervical vertebra; lacks body and
spinous process; superior articulating processes are like
concave ovals that act as rocker like cradles for condyles
of occipital bone named atlas because it supports the
head as atlas supports the world in Greek mythology.(1)

14. Axis- is the second cervical vertebra, so named because atlas
rotates about this bone in rotating movements of the head. Peg
like projections upward from the body of axis forms a pivot for
rotation of the atlas.(1)

15. • The next 12 vertebrae, 12 pairs of ribs attached to these, are
stronger with more massive bodies that cervical vertebrae. No
transverse foramina, two sets of facets for articulations with
corresponding ribs (one on body the second on transverse
process). The upper thoracic vertebrae with elongates spinous
process. (1

16. lumbar vertebrae
The next five vertebrae are strong and massive.
Superior articulating processes are directed
medially instead of upward. The inferior
articulating processes are laterally instead of
downward. These have a short blunt spinous
process.(1)

18. • .Sacrum-
• This bone is really five separate vertebrae until 25
years old, then they are fused to form one wedge-
shaped bone.(1)
• Sacral promontory- is a protuberance from anterior,
upper border of sacrum into pelvis. This is very
important because its size limits the anteroposterior
diameter of pelvic inlet.(1)
• 5.coccyx-
• Is four or five separate vertebrae in a child but fused
to one in an adult.(1)
