Answer 1

(9) 1. biaxial,oval, concave and convex- (b) condylar joint

2. multiaxial, head fits into a socket- (a) ball-and-socket

3. multiaxial, resembles the shape of a saddle- (f) saddle joint

4. uniaxial, concave and convex surfaces- (c) hinge joint

5. uniaxial, round surface in ring- (d) pivot joint

6. uniaxial, two flat surfaces- (e) plane joint

(10) (c) pivot joint; atlantoaxial joint
