Explanation:
- Neurons are basic structural and functional units of Nervous system.
- Neurons possess electrical excitability, the ability to respond to a stimulus and convert it into a action potential.
- Neurons can be classified on the basis of their structure and function.
- On the basis of structure neurons are classified as, Multipolar neuron;Bipolar neuron; Unipolar neuron.
- On the basis of function neurons are classified as, Afferent or sensory neuron; Efferent or motor neurons; Interneurons or association neurons.
