The gripping of the trochlea by the trochlear notch constitutes the "hinge" for the elbow joint.
The structural classification of joints is based on the composition of the binding material and
the presence or absence of a joint cavity.
Synovial fluid contains phagocytic cells that protect the cavity from invasion by microbes or
A person who has been diagnosed with rheumatoid arthritis would be suffering loss of the

Connective tissue sacs lined with synovial membranes that act as cushions in places where
friction develops are called ________.
The ligaments that protect the alignment of the femoral and tibial condyles and limit the
movement of the femur anteriorly and posteriorly are called ________.
All synovial joints are freely movable.
In the classification of joints, which of the following is true?
In symphysis joints the articular surfaces of the bones are covered with ________.
It contains hyaluronic acid.
Synovial fluid is present in joint cavities of freely movable joints. Which of the following
statements is true about this fluid?
cartilaginous joints where hyaline cartilage unites the ends of bones
Which of the following statements defines synchondroses?
Gliding movements occur at the intercarpal and intertarsal joints.
Which of the following is a true statement regarding gliding movements?
What is moving a limb away from the median plane of the body along the frontal plane
rare because of the ligament reinforcement
Compared to the shoulder, displacements of the hip joints are ________.
medial collateral, medial meniscus, and anterior cruciate
Football players often sustain lateral blows to the extended knee. Which of the ligaments is
(are) damaged as a result?
Which of the following conditions is generally considered a noninflammatory type of
excessive blood levels of uric acid deposited as crystals in the soft tissue joints
What can cause gouty arthritis?
Presence of a synovial cavity, articular cartilage, synovial membrane, and ligaments are
characteristics of what type of joint?
lateral and medial collateral ligaments preventing lateral or medial angular movements
Extracapsular ligaments stabilizing the knee include ________.
Joints develop in parallel with bones.
Which of the following is a correct statement about development of joints?
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.
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?
Once long bone growth in length is complete, the cartilage of the epiphyseal plates
ossifies to become a permanent synostosis.
Why are epiphyseal plates considered temporary joints?
Using the functional classification, a freely movable joint would be called a ________ joint.
articular cartilage, a joint cavity, an articular capsule, synovial fluid, and reinforcing
Synovial joints have five major features. What are they?
Exercise does not prevent arthritis, but it strengthens muscles that in turn support and
Often people who exercise prudently seem to have fewer bouts with osteoarthritis. Will
exercise prevent arthritis? If so, how?
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.
