Meaning
A sensory neuron is a specialsed cell in the nervous system which transmits an electrical impulse to the central nervous system.
About Sensory Neurons
- Sensory neurons transmit the electrical impulse produced by the receptor cells to the relay neurons in the spinal cord.
- The receptor cells sends an electrical impulse into the dendrites, past the cell body, down the axon and to the synapse where the sensory neuron connects to a relay neuron.
