Day 8 (pg 172)

Question 1

What are the attachment sites for the accessory atlanto-axial ligament?

Answer 1

the base of the odontoid process and vertebral body of axis to the tubercle for the transverse atlantal ligament on the lateral mass of C1; a superior continuation may attach on the occipital bone just behind that of the alar ligament

Question 2

What ligament forms the medial, posterior boundary of the intervertebral foramen at C1/C2?

Answer 2

the posterior atlanto-axial ligament

Question 3

What are the degrees of movement facilitated at the atlanto- axial joint?

Answer 3

about 20 degrees flexion- extension, 40 degrees one side axial rotation, and 5 degrees of lateral bending

Question 4

The occiput C1-C2 joint complex accounts for what percent of all cervical axial rotation?

Answer 4

about 60%

Question 5

What are the attachment sites for the apical ligament of the dens or apicodental ligament?

Answer 5

the anterior margin of the foramen magnum and the tip of the odontoid process of C2

Question 6

What is the embryonic derivative of the apical ligament of the dents or the apicodental ligament?

Answer 6

the notochord

Question 7

What are the attachment sites for the superficial layer of the membrane tec toria or tectorial membrane?

Answer 7

the posterior part of the inferior epiphyseal rim and vertebral body of C2 to the capsular ligament of the atlanto-occipital joint and cranial dura of the posterior cranial fossa

Question 8

What are the attachment sites for the deep layer of the membrane tec toria or tectorial membrane?

Answer 8

the posterior part of the inferior epiphyseal rim and vertebral body of C2 to the periosteum behind the cruciate ligament attachment site on the anterior rim of the foramen magnum

Question 9

For the cervical spine below C2, what is the range of motion allowed for each type of joint motion identified?

Answer 9

90 degrees flexion-extension, 50 degrees one side lateral bending and 33 degrees one side axial rotation

Question 10

What are the locations for the costovertebral joints on the vertebra?

Answer 10

the costocentral joint at the vertebral body and costotransverse joint at the transverse process

Question 11

Costocentral radiate or stellate ligaments will attach the head of the rib to what structures?

Answer 11

both the vertebral bodies of the costocentral joint and the intervertebral disc for ribs 1-9

Question 12

An intra-articular ligament will be identified with which ribs?

Answer 12

ribs 2-9

Question 13

Which vertebrae will have a synovial plane (diarthrosis arthrodia) costotransverse joint?

Answer 13

typically T1-T10

Question 14

At what rib will the superior costotransverse ligament be absent?

Answer 14

the first rib

Question 15

What ligaments will attach to the neck of the twelfth rib?

Answer 15

the superior costotransverse ligament from T11 and the lumbocostal ligament from L1

Question 16

What unique ligament is present at the twelfth rib?

Answer 16

the lumbocostal ligament

Question 17

Which ribs will have an attachment for the inferior costotransverse ligament?

Answer 17

rib 1- rib 11

Question 18

At what rib will the inferior costotransverse ligament be absent?

Answer 18

the twelfth rib?

Question 19

What is the name of the space between the transverse process and the neck of the rib?

Answer 19

the costotransverse foramen

Question 20

Which ligament “fills” the costotransverse ligament?

Answer 20

the inferior costotransverse ligament

Question 21

At what rib will the lateral costotransverse ligament be absent?

Answer 21

the twelfth rib

Question 22

Which vertebral couples of the thoracic spine have the greatest motion?

Answer 22

T11/T12 and T12/L1

Question 23

Which range of motion is greatest for lower thoracic vertebral couples?

Answer 23

flexion- extension

Question 24
