articular cartilage
2. Joint cavity enclosed by an articular
capsule
3. Synovial membrane made of dense
regular connective tissue

articular cartilages in the affected joint?
1.
2.
3.
4.
Synovial fluid nourishes articular
cartilage.

circulation.

What are menisci and what is their function?
1.
2.
3.
4.
Another name for bursae/reducing friction
Pads of fibrocartilage/subdivides a synovial
cavity and allow for variations in shape of
articular surfaces.
Fat pads/protect articular cartilage

is _____?
1.
2.
3.
4.

3.
4.
Biaxial saddle joints
Biaxial ellipsoidal joints
Monaxial pivot joints

Which regions of the vertebral column do not
contain intervertebral discs? Why is the absence of
discs significant?
1. Between sacral vertebrae; these
vertebrae are fused.
2. Between coccygeal vertebrae; these
vertebrae are fused.
3. Between the atlas and the axis; a disc
would prevent rotation.
4. All of the above are correct.

moving the head to signify “no”?
1.
2.
3.
4.

(a) lateral flexion; (b) flexion; (c) rotation
(a) rotation; (b) lateral flexion; (c) flexion
(a) flexion; (b) lateral flexion; (c) rotation

Would a tennis player or a jogger be more likely to
develop inflammation of the subscapular bursa?
Why?
1.
2.
3.
4.
tennis player; stronger muscles in the back
tennis player; repetitive shoulder motion
jogger; excessive pectoral swinging motion
jogger; bursitis develops from running
A football player received a blow to the upper
surface of his shoulder, causing a shoulder
separation. What does this mean?

2.
3.
4.

happens in their jobs.
