False
Which of the following statements is correct?

Which statement about the knee is INCORRECT?
The deep cups created by the tibial condyles help to stabilize the joint.

The glenohumeral joint is more mobile, making it less stable.
Which of the following best describes all of the joints in this figure?
They are immovable.
Which of the following is a feature of synovial joints?
bone ends covered with hyaline cartilage

cartilaginous
Which of the following is NOT a functional classification for joints?
cartilaginous
Synovial joints are classified into six main categories based on __________.
shape of articular surfaces
Which of the following best describes the joint labeled B in the figure?
synarthrotic
Which of the following are correctly paired?
synchondrosis; a plate of hyaline cartilage unites the bones
Which joint in the figure is capable of multiaxial movement?
A
Which structure in the figure is the primary area of degeneration in osteoarthritis?
B
Which of the following is one difference between bursae and tendon sheaths?
Bursae are flattened fibrous sacs wedged between adjacent structures, while tendon sheaths are elongated fibrous sacs that wrap around tendons.
Which of the following is a hinge joint?
F
Which of the following is true regarding the structure indicated by the arrow in Figure A?
It becomes ossified late in adult development.
Which inflammatory joint disease is caused by the bites of ticks that live on mice and deer?
Lyme disease
Despite having an actual articulation with the humerus, the hinge-like action at the elbow is NOT dependent on the radius.

amphiarthrosis
Which of the following ligaments prevents the tibia from sliding forward in the knee joint?
anterior cruciate ligament
Structures C and D collectively form which of the following?
articular capsule
To realign an anteriorly dislocated Temporomandibular joint (TMJ), a physician must push the mandible inferiorly and posteriorly in order to move the mandibular condyle past the temporal bone's ________.
articular tubercle
Which of these terms best categorizes the joints in the figure?
cartilaginous joints
What element of intervertebral disc fibrocartilage gives it its ability to resist stretching?
collagen fibers
The main reason the hip joint is stable is because of the __________.
deep socket of the joint and strong capsular ligaments

the deepest articular surface
Which joint allows a side-to-side movement called lateral excursion?
the temporomandibular joint
