Susan Levin 2011

2. What muscles are you using right now?
Make a list

3. Exit Ticket What are the functions of the muscular system?
Why do muscles work in pairs?

4. Science Words to know Muscle Voluntary muscle Involuntary muscle
Skeletal muscle
Smooth muscle
Cardiac muscle
Tendon

5. What do muscles do? Hold my organs in place
Hold my bones together so that I can move
Help me digest my food
Help me breathe
Open and close my eyelids
Pump my blood
Allow me to run and play
Help me to smile

6. Functions of the muscular system
Produce movement
Maintain Posture
Stabilize joints
Generate heat

7. Moving the human body Muscles of the body
Muscle - an organ that contracts and gets shorter- this provides the force to move your body parts.
Muscles and bones work together, coordinated by the nervous system
Muscles of the
body

8. Parts of the muscular system
Muscles – over 600
Tendons
Tendons attach muscles to bone helping your body move.
Feel your tendon right above your heel in the back of your leg. This is the thickest tendon in your body – Achilles tendon.

9. What are muscles made of?
Stretchy, elastic muscle cells
Made of proteins
What else is stretchy like a muscle?

10. Muscle Control
Voluntary muscles - muscles that you are able to control
Can you think of examples?
Involuntary Muscles - you can not move them consciously. They just keep working
What muscles are both voluntary and involuntary? (I can think of 2)

11. Where to find information

Types of muscles
Muscles

14. Types of Muscles - Skeletal
Skeletal Muscles-muscles that move bones
Attached to bones by tendons
Most numerous in the body
Look striped or striated
Voluntary muscles
Tire easily
Quick to react

15. Types of Muscles - Smooth Muscles
Smooth muscles - non-striated
Involuntary
Move the internal organs
Contract and relax slowly
Example- small intestine, stomach, digestive system, bladder

16. Types of Muscles - Cardiac Muscle
Cardiac muscle - found only in the heart
Involuntary
Striations (stripes)
Contracts about 70 times a minute every day of your life.
Does not tire
Slow to react
Medmovie : heart anatomy … then anterior heartbeat

17. How Muscles Work Kidshealth.com
Skeletal muscles – work in pairs - when one muscle contracts- another muscle relaxes muscles work in pairs - bbc
Muscles always PULL - never push
Muscles use glucose and oxygen to make energy
Produce heat when they contract
Muscles that are not exercised become smaller

What kinds of foods are high in protein?

20. Exercise every day.
What are some things you can do every day to help keep your muscular system healthy?

21. Learning “Write”:
If smooth muscles had to be consciously controlled what problems do you predict in day-to-day living? Write a story.
Write an article for the Courier about preventing skeletal and muscular injuries. Focus on ways the athletes can reduce the risk of injuries. Use textbook p
