Answer
The functional classification of neurons is done on the basis of the direction in which the signal travel relative to CNS. According to this, there are three types of neurons:
1. Sensory neurons
2. Motor neurons
3. Inter neurons
Work Step by Step
Sensory neurons transmit the signals from sensory receptors to the CNS.
Motor neurons transmit information away from CNS to some type of effector.
Inter neurons are located between motor and sensory neurons and help in signal integration.
