1

Which mammals do not have seven cervical vertebrae?

the two-toed sloth, manatee, ant bear, and three-toed sloth

2

Which mammals have more than seven cervical vertebrae?

ant bear, three-toed sloth

3

Which mammals have less than seven cervical vertebrae?

two-toed sloth, manatee

4

What is the number of vertebrae in the typical cervical spine?

seven segments

5

Which vertebrae are typical cervicals?

C3-C6

6

Which vertebrae are atypical cervicals?

C1, C2, C7

7

What is the shape of the typical cervical vertebral body from the cranial view?

rectangular

8

What is the appearance of the typical cervical vertebral body from the lateral view?

posterior height is greater than anterior height by a few millimeters

9

What would be the direction of the cervical curve based on osseous features?

posterior or kyphotic

10

What accounts for the direction of the typical cervical curve?

the intervertebral disc height

11

What is the direction of the typical cervical curve?

anterior or lordotic

12

Which vertebral couples will demonstrate a decrease in intervertebral disc height?

C2/C3 down to C4/C5

13

At which vertebral couple will the cervical curve again increase intervertebral disc height?

C5/C6

14

What are the names of the lateral modification of the superior epiphyseal rim?

uncinate process, unciform process, uncovertebral process, uncus or lateral lip

15

What are the modifications of the inferior epiphyseal rim of a typical cervical?

anterior lip, posterior lip, right and left lateral grooves

16

What is the joint classification for the anterior lip-anterior longitudinal ligament-anterior groove articulation?

fibrous (amphiarthrosis) syndesmosis

17

What is the joint classification for the posterior lip-posterior longitudinal ligament-posterior groove articulation?

fibrous (amphiarthrosis) syndesmosis

18

What is the joint classification for the uncinate process-lateral groove articulation?

modified synovial saddle (diarthrosis sellar)

19

What is the joint classification for the spongy bone-intervertebral disc articulation?

cartilaginous (amphiarthrosis) symphysis

20

How many joints are present on the upper surface of a typical cervical vertebral body?

five

21

How many joints are present on the lower surface of a typical cervical vertebral body?

five

22

How many total joint surfaces are present on the vertebral body of a typical cervical?

ten

23

What is the name given to the uncinate process-later groove articulation?

joint of Luschka or uncovertebral joint

24

The joint of Luschka is formed from what surfaces?

the uncinate process and lateral groove

25

How many total synovial joint surfaces are present on the vertebral body of a typical cervical?

four

26

What is the functional significance of the joint of Luschka?

it appears to stabilize the intervertebral disc while accommodating flexion-extension and requiring coupled motion (axial rotation with lateral bending) in the cervical spine

27

What muscle attaches to the typical cervical vertebral body?

the longus colli muscle

28

What is the orientation and angulation of the pedicle of a typical cervical?

posterolateral, 45 degrees

29

In the vertebral couple, which cervical vertebral body will contribute more toward the height of the intervertebral foramen?

neither, both contribute equally to the intervertebral foramen height

30

What is the direction of the projection of the cervical lamina?

posteromedially
