Answer 1

Answer:

A)Ball-and-socket joint, also called spheroidal joint, in vertebrate anatomy, a joint in which the rounded surface of a bone moves within a depression on another bone, allowing greater freedom of movement than any other kind of joint.

B)Lower jaw bone (Mandible bone) is the only skull bone which is movable.
