1

Which mammals have more than seven cervical vertebrae?

Ant bear, three-toed sloth

2

Which mammals have less than seven cervical vertebrae?

Two-towed sloth, manatee

3

Which vertebrae are typically cervicals?

C3-C6

4

Which vertebrae are atypical cervicals?

C1, C2, C7

5

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

Rectangular

6

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

7

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

Posterior or kyphotic

8

What accounts for the direction of the typical cervical curve?

The intervertebral disc height

9

What is the direction of the typical cervical curve?

Anterior or lordotic

10

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

C5/C6

11

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

Anterior groove, posterior groove, right and left uncinate processes

12

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

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

13

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

Anterior lip, posterior lip, right and left lateral frooves

14

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

Anterior lip, posterior lip, right and left lateral grooves

15

What are the names given to the lateral modifications of the inferior epiphyseal rim?

Lateral groove or enchancrure

16

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

Fibrous (amphiarthrosis) syndesmosis

17

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

Modified synovial saddle (diarthrosis sellar)

18

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

Cartilaginous (amphiarthrosis) symphysis

19

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

Five

20

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

Five

21

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

Ten

22

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

Four

23

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

Joint of Luschka or uncovertebral joint

24

What does the recent literature suggest as to the nature of the joint of Luschka?

The joint is representative of intervertebral disc aging which results in loss of lamellar integrity near the joint

25

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

26

What muscle attaches to the typical cervical vertebral body?

The longus colli muscle

27

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

Posterolateral, 45 degrees

28

What ligament attaches to the lamina of a typical cervcial?

Ligamentum flavum

29

What joint classification will be associated with the ligamentum flavum and its attachment?

Fibrous (amphiarthrosis) syndesmosis

30

Ossification of the ligamentum flavum at the attachment site on the lamina will result in what feature?

Para-articular processes
