| Sensory neurons
Sensory neurons are the nerves which transmit the external stimulus from the external structures to the brain as chemical impulses, which are the senses like touch, hearing, taste, vision . . etc. According to wikipedia: sensory neurons are neurons that are activated by sensory input (vision, touch, hearing, etc.), and send projections into the central nervous system that convey sensory information to the brain or spinal cord. Unlike neurons of the central nervous system, whose inputs come from other neurons, sensory neurons are activated by physical modalities such as light, sound, temperature, chemical stimulation, etc.
