Slide 8 - Drag question

Next to bones and joints, what else do you need for movement?

Slide 9 - Open question

Today we will learn about MUSCLES! 
 
There are three types:

1. voluntary muscles (you decide to move)
2. involuntary muscles (you can't control it)
3. cardiac muscle (in your heart)

Slide 10 - Slide

Muscles (voluntary or skeletal)
  • Muscles are attached to bones by tendons 
  • They constist of small fibres

Slide 11 - Slide

Slide 12 - Slide

Muscles move the bones
Muscles can only contract
          - it becomes shorter and thicker
Some muscles need other muscles to relax

Slide 13 - Slide

Slide 14 - Link

Slide 15 - Video

Muscles at work
Because muscles can only contract, They work in pairs.
  • Example: Biceps and Triceps in the upper arm
  • They are called: ANTAGONISTIC PAIRS
       - they each do the opposite of the other

Slide 16 - Slide

Slide 17 - Slide

involuntary muscle/smooth muslce
less strong than skeletal muscle
never tires
inside your organs (like your intestines)

Slide 18 - Slide

Slide 19 - Slide

cardiac muscle
only in your heart
doesn't tire!
somewhere in between skeletal and smooth muscle

Slide 20 - Slide

Slide 21 - Slide

Slide 22 - Slide

skeletal muscle strength
1. fast twitch fibers => contract faster, tire quickly, give a lot of strength (light colour) => sprinters
2. slow twitch fibers => contract slower, don't tire quickly, have less strength (dark colour) => marathon runners

Slide 23 - Slide

The muscles in your small intestines are ...
A
voluntary muscles
B
involuntary muscles

Slide 24 - Quiz

Skeletal muscles are voluntary muscles
A
true
B
false
