Answer 2

Cervical spine

Question 3

Answer 3

C1 or atlas

Question 4

Lacks a body and spinous process, Supports the skull

Answer 4

C1 or atlas

Question 5

Allows flexion and extension of neck

Answer 5

C1 or atlas

Question 6

Has a body and spinous process, Dens (odontoid process) projects superiorly

Answer 6

C2 or axis

Question 7

Acts as a pivot for rotation of the atlas and skull, Participates in rotating the head from side to side

Answer 7

C2 or axis

Question 8

This vertebra is the peg-shaped axis, which has a special projection called the odontoid process, that the atlas pivots around. This joint allows for the side-to- side or “no” motion of the head.

Answer 8

C2 or axis

Question 9

Body is wider laterally, Spinous processes are short and bifid (except C7)

Answer 9

C3 - C7

Question 10

All articulate with ribs, Have heart-shaped bodies from the superior view, Each side of the body of T1 – T10 bears demifacets for
articulation with ribs

Answer 10

Thoracic vertebrae

Question 11

12 vertebrae of the what vertebrae

Answer 11

Thoracic

Question 12

the main function of the ___________ is to protect the organs of the chest by providing attachment for the rib cage.

Answer 12

Thoracic

Question 13

These vertebrae are much larger in size for their weight-bearing function.

Answer 13

Lumbar

Question 14

the main function of the __________ is to bear the weight of the body

Answer 14

Lumbar spine

Question 15

This vertabrae has 5 vertebrae

Answer 15

Lumbar

Question 16

Bodies are thick and robust (strong and big bone), Transverse processes are thin and tapered, Spinous processes are thick, blunt, and point posteriorly

Answer 16

Lumbar vertabrae

Question 17

Vertebral foramina are triangular, Superior and inferior articular facets directly medially, Allows flexion and extension – rotation prevented

Answer 17

Lumbar vertabrae

Question 18

5 fused vertebrae

Answer 18

Sacrum

Question 19

the _______ functions as a keystone (or wedge), stabilizing the bony pelvis.

Answer 19

Sacrum

Question 20

Shapes the posterior wall of pelvis, Formed from 5 fused vertebrae, Superior surface articulates with L5, Inferiorly articulates with coccyx

Answer 20

The sacrum

Question 21

Is the “tailbone”, Formed from 3 – 5 fused vertebrae, Offers only slight support to pelvic organs

Answer 21

Coccyx
