An introduction to the muscles in the human body The MUSCULAR SYSTem An introduction to the muscles in the human body

Learning intention I can identify and explain the function of muscles in my body.

Let’s get moving! You may use the room to: Dance Skip Hop Jump BUT you must STOP your body when the music stops

How do you feel? Which movement did you choose? Which parts of your body were you moving? What do you notice when you move your body parts? Point to a muscle in your: Arm Leg Neck Rest your hand on these muscles while you move them What do you notice?

How do they work? How do you think this rubber band may be like a muscle? Muscles have to get smaller and bigger in order to help us move Rubber band stretches and contracts just like our muscles Muscles are made from thousands of elastic-like tissues YES! Like a bunch of elastic bands!

Muscles Some muscles are moved by us on purpose Clap your hands Some muscles move on their own Make your heart beat

Muscle types There are three different muscle types in your body Smooth muscles: muscles that you cannot control Involuntary muscles Often in layers or sheets with one muscle behind the other At work all over your body EXAMPLES? Think: Digestive system Bathroom Sight

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)

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
