Flashcards in Day 8 (pg 172) Deck (24):
1

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

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

2

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

the posterior atlanto-axial ligament

3

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

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

4

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

about 60%

5

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

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

6

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

the notochord

7

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

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

8

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

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

9

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

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

10

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

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

11

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

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

12

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

ribs 2-9

13

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

typically T1-T10

14

At what rib will the superior costotransverse ligament be absent?

the first rib

15

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

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

16

What unique ligament is present at the twelfth rib?

the lumbocostal ligament

17

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

rib 1- rib 11

18

At what rib will the inferior costotransverse ligament be absent?

the twelfth rib?

19

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

the costotransverse foramen

20

Which ligament "fills" the costotransverse ligament?

the inferior costotransverse ligament

21

At what rib will the lateral costotransverse ligament be absent?

the twelfth rib

22

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

T11/T12 and T12/L1

23

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

flexion- extension

24

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

one side axial rotation
