neurones and receptors.
- Help organism to response
and coordinate.
- Information from the receptor
passes along the neurones to the
brain. The brain produces impulse
and send to the effector.
- The effector may be a muscle or a gland.
- Neurons
- Motor Neurone. Sensory Neurone.
Relay Neurone. These are cells that can carry an
electrical signal (impulse).
- Types Of Receptors
- Light
- Sound
- Taste
- Smell
- Touch, Pressure, Pain and
Temperature
- Stimulus > Receptor > Sensory Neurone > Relay Neurone > Motor
Neurone > Effector > Response.
