Answer 10

Secondary curve

Question 11

Answer 12

Pedicles

Question 13

What is the laminae in the vertebra?

Answer 13

roof of vertebral canal

Question 14

What is the relationship between cervical vertebra and nerves?

Answer 14

The cervical nerves lie above the vertebra. C1 nerve lies above C1 vertebra.

Question 15

Describe a typical TV?

Answer 15

Has two costal demifacets on the body, on the superior end to articulate with the head of rib (same #), and inferior to articulate with the head of the inferior rib

Question 16

What motion does the lumbar vertebra favor?

Answer 16

around the transverse axis (flex and extend)

Question 17

What plane are lumbar vertebra articular facets in?

Answer 17

saggital

Question 18

What motion occurs in the thoracic region?

Answer 18

Lateral flexion and extension and rotation

Question 19

The discs are thickest in what part of the spine?

Answer 19

Cervical and lumbar regions- this increases flexibility

Question 20

The discs are thinner in what region of the spine?

Answer 20

Thoracic region resulting in reduced flexibility

Answer 24

Limits flexion

base of one spinous process to the next

Question 25

Answer 25

LImits flexion and extends from lamina to lamina. Forms part of the roof of the vertebral canal

Question 26

Where is Pars interarticularis?

Answer 26

located between inferior and superior articular facets between he lamina and pedicles of vertebra
