There are five different sense organs. Which all contain different receptors.
Receptors are a groups of cells which are sensitive to a stimulus such as light or heat, etc.
When they are activated by a stimulus they generate electrical impulses.
The five sense organs and the stimuli that each of them is sensitive to:
Eyes: light receptors
Ears: sound and balance receptors
Nose: taste and smell receptors (chemical stimuli)
Tongue: Taste and smell receptors, (chemical stimuli)
Skin: touch and temperature receptors.
Other part of the Nervous System
Spinal Cord : This is the bundle of nerves that transmits information up and down the body.
Motor Neurones: The nerve cells that carry signals to from th brain to the effectors (muscle and glands).
Sensory Neurones: The nerve cells that carry signals from the receptors in the sense organs towards the brain.
Effectors : All your muscles and glands will respond to nervous impulses.
