Question

match the types of synovial joints in column a with the examples in column b. place the letter of your choice in the space provided.
column a
a. ball - and - socket
b. condylar (ellipsoidal)
c. hinge
d. pivot
e. plane (gliding)
f. saddle
column b

1. hip joint
2. metacarpal - phalanx
3. proximal radius - ulna
4. humerus - ulna of the elbow joint
5. phalanx - phalanx
6. shoulder joint
7. knee joint
8. carpal - metacarpal of the thumb
9. carpal - carpal
10. tarsal - tarsal

Explanation:

Ball - and - socket joints allow multi - directional movement and include the hip and shoulder joints. Condylar joints have an oval - shaped end fitting into an elliptical cavity, like the metacarpal - phalanx. Hinge joints allow movement in one plane, such as the elbow (humerus - ulna) and knee joints and phalanx - phalanx joints. Pivot joints allow rotational movement, like the proximal radius - ulna joint. Plane (gliding) joints allow sliding movement, seen in carpal - carpal, tarsal - tarsal joints. Saddle joints, like the carpal - metacarpal of the thumb, have a concave and convex surface fitting together.

Answer:

1. a. Ball - and - socket
2. b. Condylar (ellipsoidal)
3. d. Pivot
4. c. Hinge
5. c. Hinge
6. a. Ball - and - socket
7. c. Hinge
8. f. Saddle
9. e. Plane (gliding)
10. e. Plane (gliding)
