Using the flowchart below, identify the part of the human nervous system that is usually associated with symptoms of hypoesthesia and paresthesia.

The answer is Sensory and Motor Communication because the nervous system receives inputs and sends motor outputs in the brain. Sensory input and motor output is further subdivided according to the regions of the body they serve, either somatic or visceral. Motor or efferent signals are sent away from the central nervous system via nerve fibers, towards the peripheral nervous system and give energy or stimulation to the designated body organ or part.
