They change (increase or decrease) the angle between two bones.
Which of the following statements best describes angular movements?
The trapezium of the carpal bone and the thumb's metacarpal
Saddle joints have concave and convex surfaces. Name the two bones of the hand that
articulate to form a saddle joint.
act as friction-reducing structures
Tendon sheaths ________.
tendon sheath
Which of the following is not a part of the synovial joint?
number of bones in the joint
Which of the following is not a factor that contributes to keeping the articular surfaces of
diarthroses in contact?
inversion
Turning the foot medially at the ankle would be called ________.
protraction
Moving your jaw forward, causing an underbite, is called ________.
bursa

subluxation
Partial dislocation of a joint is called a ________.
saddle
The type of joint between the carpal and the first metacarpal is a ________ joint.

ligaments
Synovial joints have five major features. What are they?
Exercise does not prevent arthritis, but it strengthens muscles that in turn support and
stabilize joints.
Often people who exercise prudently seem to have fewer bouts with osteoarthritis. Will
exercise prevent arthritis? If so, how?
hinge, flexion
Bending the elbow: ________, ________.
pivot, rotation
Turning head side to side: ________, ________.
ball and socket, adduction
Lowering your arm to your side: ________, ________.
plane, inversion

The thumb possesses a saddle joint where each articular surface has both a concave and
a convex surface.
While the fingers can exhibit flexion and extension and other angular motions, the thumb has
much greater freedom. Why?
The ends of each bone are covered with hyaline cartilage that is continuous with the
synovial membrane enclosing the joint. Synovial fluid fills the space between the articular
cartilage. Outside the synovial membrane there is a very tough, fibrous capsule that prevents the
synovial membrane from bulging out as pressure is applied to the ends of the bones.
Describe a typical synovial joint.
