Study Notes
The Senses
Eyes
- The back of the eye has a layer of light-sensitive cells called the retina
- The retina detects light and sends messages to the brain via the optic nerve
Ear
- Detects sounds as vibrations that pass through the air
- Vibrations are magnified by the ear and messages are carried to the brain by the auditory nerve
Nose
- The inside of the nose is lined with cells that can detect different chemicals
- We learn to associate different smells with familiar things within our environment
- Information is sent from the nose to the brain along the olfactory nerve
Tongue
- Detects chemicals in the foods that we eat
- Passes information to the brain
Test your knowledge about how our senses work, including the eye, ear, and nose. Learn about the processes of detecting light, sound, and smell, and how our brain interprets these sensations.
