Flashcards in 1. Lumbar, Thoracic, Ribs, Vertebra Mechanics Deck (18):
1

What parts of the spine have kyphosis / lordosis?

Cervical lordosis

Thoracic kyphosis

Lumbar lordosis

Sacral kyphosis

2

What is a vertebral unit?

Two adjacent vertebrae and the associated intervertebral discs.

3

What is the orientation of the superior facet in the cervical spine?

Backwards

Upward

Medial

4

What is the orientation of the superior facets in the thoracic spine?

Backwards

Upward

Lateral

5

What is the orientation of the superior facets in the lumbar spine?

Backward

Medial

6

Which ligament of the spine resists extension?

Anterior longitudinal ligament

7

Which ligament of the spine resists hyperflexion?

Posterior longitudinal ligament

8

What ligament connects the laminae of adjacent vertebra?

Ligamentum flava

9

What are the bilateral and unilateral functions of the rotatores muscles?

Bilateral: extend the spine

 

Unilateral: rotate the spine

10

What is the bilateral and unilateral function of the multifidus muscle?

Bilateral: extends spine

 

Unilateral: Flexes spine to the same side, and rotates it to the opposite side.

(Recall that Mutifidus Ms. attach to the spinus processes)

11

What are the bilateral and unilateral functions of semispinalis?

Bilateral: Extends thoracic and cervical spines and head

 

Unilateral: Bends head, cervical, and thoracic spine to same side; and rotates to opposite side.

12

Who described physiologic (normal and SD) motion of the spine, and when?

Harrison Fryette

1918

13

Who developed the "third principle" of Fryette's Principles of spinal mechanics?

C.R. Nelson

(1948)

14

What spinous process can be found at the following levels?

Spine of the scapula

Inferior angle of the scapula

Iliac crest

Spine of the scapula: T3

Inferior angle of scapula: T8

Iliac crest: L4

15

What three diagnoses should be expected in a patient with pain radiating below the knee?

Spinal stenosis

rediculopathy

cauda equina syndrome

16

What diagnosis should be expected in a patient with saddle anesthesia?

Cauda equina syndrome

17

What is sacralization?

One or both transverse processes of L5 articulate with the sacrum

18

What is lumbarization?

Failure of S1 to fuse with the rest of the sacrum
