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
