Answer:
Pass information by generating electric signals
Explanation:
Neurons are the fundamental unit of the nervous system. Neurons send information across the body through generation of electric signals called as action potential. There are basically three types of neurons
a) Sensory neurons which carry information from the sense organs in the form of impulse to the central nervous system (CNS)
b) Motor neurons – These carry information from the CNS to the body parts such as sense organs, muscles etc.
c) Interneurons – They are connecting neurons which are responsible for transferring information from one neuron to the other neuron.
