1

The amount of movement permitted by a particular joint is the basis for the functional classification of joints.

True

2

All joints permit some degree of movement, even if very slight.

False

3

Hinge joints permit movement in only two planes.

False

4

Synovial fluid is a viscous material that is derived by filtration from blood.

True

5

The articular surfaces of synovial joints play a minimal role in joint stability.

True

6

The major role of ligaments at synovial joints is to help direct movement and restrict undesirable movement.

True

7

The only movement allowed between the first two cervical vertebrae is flexion.

False

8

Movement at the hip joint does not have as wide a range of motion as at the shoulder joint.

True

9

A person who has been diagnosed with a sprained ankle has an injury to the ligaments that attach to that joint.

True

10

The knee joint allows for extension and flexion only.

False

11

A movement of the forearm in which the palm of the hand is turned from posterior to anterior is supination.

True

12

The wrist joint can exhibit adduction and eversion movements.

False

13

Cruciate ligaments are important ligaments that stabilize all ball-and-socket joints.

False

14

Moving the arm in a full circle is an example of circumduction.

True

15

Flexion of the ankle so that the superior aspect of the foot approaches the shin is called dorsiflexion.

True

16

The gripping of the trochlea by the trochlear notch constitutes the "hinge" for the elbow joint.

True

17

The ligamentum teres represents a very important stabilizing ligament for the hip joint.

False

18

The structural classification of joints is based on the composition of the binding material and the presence or absence of a joint cavity.

True

19

Chondromalacia patellae is hardening of the articular cartilage on the posterior patella surface.

False

20

Synovial fluid contains phagocytic cells that protect the cavity from invasion by microbes or other debris.

True

21

A person who has been diagnosed with rheumatoid arthritis would be suffering loos of the synovial fluids.

False

22

A ball-and-socket joint is a multiaxial joint.

True

23

Bending of the tip of the finger exhibits flexion.

True

24

A nonaxial movement is usually seen at a joint such as a hinge.

False

25

Dislocations in the TMJ almost always dislocate posteriorly with the mandibular condyles ending up in the infratemporal fossa.

False
