What is the function of a neurone?
The CNS (Central Nervous System) consists of the brain and the spinal cord. Neurones, found in the nervous system, are nerve cells that carry information in the form of electrical signals/impulses. There are 3 different types of neurones: 1. Sensory neurones: carry signals from the receptors to the CNS 2. Motor neurones: carry signals from the CNS to the effectors 3. Relay neurones: carry signals from one part of the CNS to another. A single neurone consists of a nucleus, cytoplasm, cell membrane, dendrite, axon and nerve ending. When two neurones meet, they meet at a synapse (gap between 2 neurones) where the signals are transmitted from one neurone to the next using chemicals. At the synpase, one neurone releases the chemical across the gap which diffuses and causes an electrical signal to be transmitted to the next neurone.
