Resource summary
The Nervous System
You have five sense organs.
They all contain different RECEPTORS-groups of cells which are sensitive to specific stimuli.
A STIMULUS can be anything from
Light
Sound
Pressure
Chemical
Change in position or temperature.
RECEPTORS work by changing stimulus energy to electric impulses.
The five sense organs and the receptors they contain.
Eyes-Light receptors
Ears-Sound and Balance receptors.
Nose-Smell receptors-sensitive to chemical stimuli.
Tongue-taste receptors for bitter, salt, sweet, sour plus savoury eg Monosodium Glutamate.
Skin-sensitive to touch, pressure and temperature change.
The Central Nervous system
Consists of Brain and spinal cord ONLY.
Where all information from organs is sent & where reflexes and actions are co-ordinated.
Neurones (nerve cells)
Transmit the information (as electric impulses) very quickly to and from the CNS.
Sensory Neurones-The nerve cells that carry signals as electrical impulses from the receptors in sense organs to CNS
Motor Neurones: Nerve cells that carry signals to the effector muscles or glands.
