Planning
  •  See what you remember from last week
  • B4: muscles
  • Make exercises

Slide 1 - Tekstslide

Learning goals
  • You can explain how the muscles work.
  • You can give examples of voluntary and involuntary muscle movements.

Slide 2 - Tekstslide

But first... lets see what you remember from last week!

Slide 3 - Tekstslide

Verbind de verbinding met het juiste plaatje. In plaatje 1 wordt het staartbeen bedoeld!
joint
sutures
fused vertebrae
cartilage

Slide 4 - Sleepvraag

The socket bone and ball-shaped bone both have
a cartilage layer.

Explain why the cartilage is right there.

Slide 5 - Open vraag

The joint of the shoulder is the same as the joint in the hip.

Explain why elderly people often have more damage of the cartilage layer in their hip joint than in their shoulder joint.

Slide 6 - Open vraag

what is the joint with the most movement possible?
A
ball-and-socket joint
B
hinge joint
C
pivot joint

Slide 7 - Quizvraag

4.4 Muscles

Slide 8 - Tekstslide

Slide 9 - Video

Muscular system
Muscles let you stand up straight and move about. 

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


Slide 10 - Tekstslide

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 11 - Tekstslide

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

Flexor muscle = Buigspier
extensor muscle= Strekspier



Slide 12 - Tekstslide

Slide 13 - Tekstslide

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
