Answer : The features of neurons help them to carry out their function efficiently:
- they have a long fibre (axon) so they can carry messages up and down the body over long distances
- in a stimulated neuron, an electrical nerve impulse passes along the axon
- the axon is insulated by a fatty (myelin) sheath - the fatty sheath increases the speed of the nerve impulses along the neuron
- at each end of the neuron are tiny branches (dendrons), which branch even further into dendrites - the dendrites receive incoming nerve impulses from other neurons.
