Movement
The General Level work you have done in this subtopic should enable you to:
name the main bones on a diagram of the skeleton
know that the skeleton gives the body support, and why it is needed for
movement
know that the skeleton gives protection and give examples of parts of the
skeleton which protect important organs
describe how a hinge joint moves and give examples two hinge joints in the
body
describe how a ball and socket joint moves and give examples of two ball
and socket joints in the body
know what ligaments do
know what cartilage does in a joint
know the two types of material which make up bone, know why each material
is important, and describe experiments which remove each of these materials
know what tendons do
describe how muscles brings about movement at a joint

know that bone is formed by living cells
describe the detailed structure of a joint, naming the parts and explaining
what they do
explain why tendons are less elastic than ligaments
explain why a joint must have a pair of opposing muscles
