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

True

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

False

Hinge joints permit movement in only two planes.

False

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

True

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

True

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

True

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

False

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

True

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

True

The knee joint allows for extension and flexion only.

False

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

True

The wrist joint can exhibit adduction and eversion movements.

False

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

False

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

True

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

True

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

True

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

False

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

True

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

False

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

True

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

False

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

True

Bending of the tip of the finger exhibits flexion.

True

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

False

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

False
