Show transcript
Neurones are specialised cells that transmit nerve impulses
The common structures of neurones, including cell body and axon
A myelin sheath on some neurones increases the speed of the nerve impulse
Nerve impulses pass from one neurone to another across a gap called a synapse
An impulse arriving at a synapse releases neurotransmitters that diffuse across the gap to receptors on the next neurone
