The Five Senses
- Touch
Receptors in your skin sense different types of touch and send signals to your brain so that you feel your surroundings.
- Smell
The nose detects odour molecules in the air and sends signals to the brain so that you can smell them.
- Vision
Eyes detect light and send signals to the brain, which produces moving images of your surroundings.
- Hearing
Ears detect sounds and send signals to the brain, which identifies them as sounds you can hear.
- Taste
The tongue's taste buds detect taste molecules in food and send signals to the brain so that you taste what you're eating.
