Answer:
<u>Motor neurons </u>send messages to the muscles and glands to respond to stimuli.
<u>Sensory neurons </u>move information towards the central nervous system for processing.
<u>Interneurons </u>carry information from one type of neuron to another.
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.
