Answer 20

.

Question 21

Cartilage acts as a cushion between bones to prevent damage during joint movement as it also helps aid the stability of a joint

Answer 21

.

Question 22

The Synovial membrane releases a synovial fluid into the joint capsule to lubricate the joint allowing it move easier

Answer 22

.

Question 23

The Different types of Joint movement are Flexion, extension, rotation, circumduction, adduction and adduction

Answer 23

.

Question 24
