Question 17

Pivot joint

Answer 17

Pivot joints allow bones to rotate. In a pivot joint, one bone shaped like a
cylinder rotates inside another bone or ligament that makes a ring round it.
You have three pivot joints in your body: in your wrist, elbow and neck.

Question 18

Hinge joint

Answer 18

A hinge joint is a joint that allows only backward and forward motion - just like
the hinge on a door. There are three hinge joints: the knee, elbow and ankle.

Question 19

Ball and socket

Answer 19

In a ball and socket joint, the rounded head of a long bone (the ball) fits
into a cup-shaped hole (the socket). Both the hip and the shoulder joints
are ball and socket joints. With the hip, the long femur fits into the pelvis;
with the shoulder, the long humerus fits into the scapula. In both the hip
and the shoulder the bones are covered with cartilage and reinforced with
ligaments, but the shoulder joint has more freedom than the hip and is
capable of more variety and a bigger range of movement.

Question 20

Condyloid joints

Answer 20

A condyloid joint is similar to a ball and socket joint, but the ball rests against
the end of a bone, rather than inside a socket. This allows circular motion.
