Question 1

What is a joint

Answer 1

A joint is a place where two or more bones meet.

Joints are important for movement and rotation.

Question 2

Pivot joint

Answer 2

Pivot joint, in vertebrate anatomy, a freely moveable joint (diarthrosis) that allows only rotary movement around a single axis.

Question 3

Hinge joint

Answer 3

Hinge joints are a type of joint that functions much like the hinge on a door, allowing bones to move in one direction back and forth with limited motion along other planes.

Question 4

Ball in shocket joint

Answer 4

Ball-and-socket 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.

Question 5

A condyloid joint is an ovoid articular surface, or condyle that is received into an elliptical cavity. This permits movement in two planes, allowing flexion, extension, adduction, abduction, and circumduction.
