Ans,On the basis of their functions, neurons are classified into three types:
1. Sensory neurons conduct sensory information (nerve impulse) from receptors towards the CNS. Sensory neurons have one dendrite and one-axon.
2.Interneurons form brain and spinal card. They receive information, interpret them and stimulate motor neurons. They have many dendrites and axons.
3.Motor neurons carry information from interneuron's to muscle* or glands : (effectors). They have many dendrites but only one axon.
