Key Stage 4
Meaning
A relay neuron is a specialsed cell in the central nervous system which relays an electrical impulse from a sensory neuron to a motor neuron.
About Relay Neurons
- Relay neurons are found in the Spinal Cord.
- Relay neurons are part of the reflex arc.
- The relay neuron receives an electrical impulse from the sensory neuron. The impulse passes into the dendrites, through the cell body, down the axon and to the synapse where the relay neuron connects to a motor neuron.
