Sensing things

Slide 5 - Tekstslide

Sensing things
You see and smell chocolate
Using sense organs
Signal (impulse) through nerves to your brain
Brain send impulse to arm muscle -> you grab the chocolate

Slide 6 - Tekstslide

Sense organs = zintuigen
Eyes, ears, nose, tongue, skin

Slide 9 - Quizvraag

All your senses together form the ...
nervous system
sensory system
brain system
sense canal

Slide 10 - Quizvraag

How do you call the signals the sense organs send out?

Slide 11 - Open vraag

Sense receptors in the skin

Cold receptors
Pressure receptors

Slide 12 - Tekstslide

Reacting to the surrounding
Stimulus (prikkel) = information from the surrounding
Light, temperature, smell, sounds, skin contact

Stimulus -> sense organ -> impulse -> nerves -> brain 
Brain responds with a impulse to the muscles to react 

Slide 13 - Tekstslide

Sensory cells
Sensory organs have sensory cells
Which are connected to nerves

When the sensory cells receive a stimulus they generate an impulse (kind of electrical signal)

Slide 14 - Tekstslide

Fill in the right words:
The smell of a fresh panini comes into your nose, this is called a .... Then a .... is sent through the nerves to the brain.
