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
