Biology 2-nervous system
The nervous system is made up of two parts-the central nervous system and the peripheral nervous system
The brain and the spinal cord form the CNS which interprets and coordinates the information
The PNS has nerves and receptors
Receptors are cells or modified nerve endings which can respond to a stimulus
The receptors detect stimuli and send electrical impulses to the CNS
There are 5 sense organs-the eyes, skin, ears, nose and tongue
The ear detects sounds and converts them to electrical signals
Light enters the eye through a pupil
The nose and tongue both have sensory cells to detect dissolved substances
The nervous system contains many nerve cells called neurones
Reflex actions is a rapid automatic response which protect the body e.g. makes you take your hand away from a hot object
Synapses are junctions in-between neurones. The synapses pass information between neurones.
Dendrites are at the ends of the nerve cell bodies and they interconnect with neurones to pass the nerve impulses from one neurone to another
