Slide 13 - Quiz

Muscular system
Grab your notebook and a pen. 
Title: Unit 4 basic 4 muscular system

Muscles let you stand up straight and move about. 

All the skeletal muscles in your body combined form the muscular system


Slide 14 - Slide

Tendons
The muscle is attached to the bone by tendons (pezen). The point where the tendon is attached to the bone is called the attachment site (aanhechtingsplaats).


Muscles are able to contract, but tendons are not. 
Bones move because of the muscle contractions.


Slide 15 - Slide

Antagonistic pair
To move a bone, you always need two muscles: a flexor muscle and an extensor muscle. These two muscles have opposite effects.
= antagonistic pair




Slide 16 - Slide

organ muscle
In addition to the skeletal muscles, you also have muscles in your organs. These organ muscles move without you being aware of it.

For example:
-Heart
-muscles in your oesophagus, stomach, intestines
