3. Different Types of Muscle
Muscles of the body Muscle is joined onto the bone by a strong, semi-elastic component called a tendon. Bones are joined to other bones and are held in position by very strong, inelastic fibrous bands called ligaments. When ligaments get damaged, bones can be dislocated. Skeletal Muscle Muscles provide force for movement, pulls bones around a joint, either closer together or further apart, allowing movement to occur

6. Muscles and Movements Muscles cannot push they can only pull
For any movement to take place, muscles have to work in pairs
One muscle pulls by shortening its length (contracting).
While its partner relaxes and lengthens (extending).
This causes movement at the joint
Page 37 work book

7. Muscles and Movements
Agonist – The muscle that contracts during the movement. e.g. bicep muscle during a bicep curl
Antagonist – The muscle that relaxes to allow the movement.
Hint:
Agonist = short word =
short muscle (contract)
Antagonist = long word =
long muscle (relaxed)

8. How your muscles move
Place your left hand on your right bicep. Move your right arm up and down as if you were doing a bicep curl
Stand up and place your hands on your thigh/quadricep. Bend your leg at your knee
During these movements which is your agonist/antagonist muscles?
