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
