Make your heart beat

Involuntary muscles
Often in layers or sheets with one muscle behind the other
At work all over your body

Digestive system
Bathroom
Sight

8. Muscle types Cardiac muscle: the muscle that makes up the heart
Myocardium
Muscle contracts to pump blood out and relaxes to let blood in
Also involuntary (like smooth muscles)

9. Muscle types
Skeletal muscles: the ones you think of when we say muscles
Help to make up the musculoskeletal system
Combination of your muscles and bones
Voluntary muscles (you can control these!)
Skeletal muscles work with your bones to give your body
power and strength
Attached to one end of a bone, stretched across a joint
and attached to the end of another bone
Tendons are connectors between bone and muscle
