Which mammals have more than seven cervical vertebrae?

ant bear, three-toed sloth

1

Which mammals have less than seven cervical vertebrae?

two-toed sloth, manatee

2

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

seven segments

3

Which vertebrae are atypical cervicals?

C1, C2, C7

4

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

rectangular

5

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

6

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

posterior or kyphotic

7

What accounts for the direction of the typical cervical curve?

the intervertebral disc height

8

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

C5/C6

9

What is the direction of the typical cervical curve?

anterior or lordotic

10

What is the effect of aging on the cervical vertebral body?

it diminishes the overall height of the vertebral body

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?

unicinate 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 grooves

14

At what developmental age will the uncinate process first be observed?

3rd -4th fetal month

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 anterior lip-anterior groove articulation?

fibrous (amphiarthrosis) syndesmosis

17

What is the joint classification for the posterior lip-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

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

five

20

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

cartilaginous (amphiarthrosis) symphysis

22

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

five

22

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

four

23

how many joint surface are present on the vertebral body of a typical cervical?

ten

24

What other term is used to identify the lateral groove?

enchancrure

25

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

joint of Luschka or uncovertebral joint

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 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

28

What muscle attaches to the typical cervical vertebral body?

the longus colli muscle

29

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

posterolateral, 45 degrees
