Day 14 (Typical Cervical Vertebrae C3-C6)

Question 1

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

Answer 1

cartilaginous (amphiarthrosis) symphysis

Question 2

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

Answer 2

five

Question 3

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

Answer 3

ten

Question 4

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

Answer 4

joint of Luschka or uncovertebral joint

Question 5

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

Answer 5

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

Question 6

What is the functional significance of the joint of Luschka?

Answer 6

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

Question 7

What muscle attaches to the typical cervical vertebral body?

Answer 7

the longus colli muscle

Question 8

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

Answer 8

posterolateral, 45 degrees

Question 9

At what location on the vertebral body of a typical cervical will the pedicle attach?

Answer 9

to the side and in the center of the vertebral body

Question 10

The greatest transverse diameter of the typical cervical vertebra occurs at …..?

Answer 10

C6

Question 11

The greatest frequency of osteophytes associated with the vertebral body occurs at which typical cervical vertebral couple?

Answer 11

C5/C6

Question 12

List, in order, the osseous parts of the typical cervical vertebra transverse process beginning at the vertebral body.

Answer 12

costal element, anterior tubercle, costotransverse bar, posterior tubercle, true transverse process (the order would be reversed if asked to begin at the lamina pedicle junction)

Question 13

What muscles will attach to the anterior tubercle of a typical cervical vertebra?

Answer 13

anterior scalene, longus capitis, longus colli, anterior intertransversarii

Question 14

What muscles may attach to the posterior tubercle of a typical cervical vertebra?

Answer 14

splenius cervicis, iliocostalis cervicis, longissimus cervicis, levator scapula, middle scalene, posterior scalene, rotators, and posterior intertransversarii

Question 15

What muscles will attach to the costotransverse bar?

Answer 15

middle scalene and posterior intertransversarii

Question 16

What is the name given to the superior margin of the costotransverse bar?

Answer 16

sulcus for the ventral primary ramus of a cervical spinal nerve

Question 17

What is the orientation and angulation of a typical cervical transverse process?

Answer 17

60 degrees anterolaterally (from midsagittal plane), 15 degrees inferiorly (from the horizontal plane)

Question 18

What is the name given to the modification of the anterior tubercle of the C6 transverse process?

Answer 18

the carotid tubercle

Question 19

What will cause remodeling of the anterior tubercle at C6?

Answer 19

the common carotid artery

Question 20

What will occupy the typical cervical vertebra transverse foramen?

Answer 20

the vertebral artery, vertebral venous plexus and postganglionic sympathetic motor nerve fibers
