Answer 4

Back;

X = supine

Question 5

Question 6

An extrinsic muscle differs from intrinsic muscle in that:

Answer 6

Extrinsic muscle has attachment outside specified body region

Question 7

What does valgus refer to?

Answer 7

Bone distal to joint deviates laterally (away from midline)

Question 8

Answer 8

Bone distal to joint deviates medially (toward from midline)

Question 9

Flexion/extension usually occurs in (X) plane of section.

Answer 9

X = saggital

Question 10

Answer 15

X = CT
Y = joints

Facilitate movement by reducing friction

Question 16

Concentric contraction is:

Answer 32

Cartilaginous

Question 33

List the components of the synovial joint.

Answer 33

1. Articular cartilage 2. Fibrous capsule 3. Synovial membrane 4. Collateral ligaments

Question 34

Articular, aka (X), cartilage is found covering (Y) in (Z) joints.

Answer 34

``` X = hyaline Y = areas of bones that come in contact Z = synovial ```
