Flashcards in Vertebral Column Deck (32):
1

Where is the pedicle on a vertebra?

It's the bilateral bit joining the body of the vertebra to the spines

2

Where is the lamina on a vertebra?

From the pedicle, these project posteromedially to form the spinous process

3

What attaches to the vertebral laminae?

Ligamentum flavae

4

Describe the positioning of the transverse processes of the vertebrae

Project from either side where the lamina joins the pedicle, between superior and inferior articular processes

5

What attaches to the transverse processes?

Costal cartilage, via articular process

6

What structure is unique to cervical vertebrae?

Transverse foraminae (for vertebral arteries)

7

Recall the normal degrees of flexion, extension, lateral flexion and rotation for the cervical spine

Flexion: 45 degrees
Extension: 45 degrees
Lateral rotation: 45 degrees
Rotation: 80 degrees

8

Recall the normal degrees of flexion, extension, lateral flexion and rotation for the throracolumbar spine

Flexion: 90 degrees
Extension: 30 degrees
Lateral flexion: 30 degrees
Rotation: 30 degrees

9

What is the name given to excessive thoracic curvature?

Exaggerated Kyphosis

10

What is the name given to excessive lumbar curvature?

Exaggerated Lordosis

11

Recall the normal primary and secondary curvatures of the spine

Primary = anterior-pointing; thoracic and sacral
Secondary = posterior-pointing; cervical and lumbar

12

Recall the names given to C1 and C2

C1 = Atlas
C2 = Axis

13

What is unique about the Atlas vertebra?

No body or spinous process

14

What does the Atlas vertebra articulate with on its superior surface?

Occipital condyles

15

What is the main weight-bearing component of the Atlas vertebra?

Lateral masses

16

What is the strongest ligament of the Axis vertebra and what is its function?

Transverse ligament
Produces foramen for dens of axis to articulate

17

What head movement is produced at the Atlanto-axial joint?

"No" - rotation on superior articular facets of axis

18

What joint is responsible for nodding of the head?

Atlanto-occipital joint

19

What is the first vertebra visible as a bony landmark in the neck?

C7

20

Recall the vertebral level of the medial end of the scapular spine

T3

21

Recall the vertebral level of the inferior angle of the scapula

T7

22

At what vertebral level is the iliac crest?

L4

23

What sort of joints are the intervertebral joints?

Cartilaginous

24

Recall the 2 main structural components of the intervertebral discs

Nucleus pulposus
Anulus fibrosus

25

What is the function of the ligamenta flava?

Connect adjacent laminae

26

Recall the 5 main ligaments found in the spine

Longitudinal ligaments - anterior and posterior
Interspinous
Supraspinous
Ligamenta flava

27

Which meninges extend into the spine, and how far do they extend?

Arachnoid and dura
--> S2

28

Define sciatica

Prolapsed intervertebral disc

29

Define spondylolithesis

Forward displacement of vertebra

32

Define spondylitis

Vertebral inflammation
