An Overview Of Nervous System Nervous systems perform the three overlapping functions of sensory input integration motor output CNS Brain Spinal cord PNS Sensory (input) Signals from external environment Signals from skin, tendons, and muscles Signals from internal organs Motor (output) Somatic division (control of skeletal muscle) Autonomic division (autonomic control of smooth muscle, cardiac muscle, and glands) Parasympathetic Sympathetic Endocrine (Hormone) *Video by bozemanbiology via YouTube Peripheral nervous system (PNS). Sensory receptors a responsive to external and internal stimuli. Such sensory input is conveyed to integration centers. Where in the input is interpreted an associated with a response.
