Control of Autonomic NS ⢠Not aware of autonomic responses because control center is in lower regions of the brain ⢠Hypothalamus is major control center â input: emotions and visceral sensory information ⢠smell, taste, temperature, osmolarity of blood, etc â output: to nuclei in brainstem and spinal cord â posterior & lateral portions control sympathetic NS ⢠increase heart rate, inhibition GI tract, increase temperature â anterior & medial portions control parasympathetic NS ⢠decrease in heart rate, lower blood pressure, increased GI tract secretion and mobility Principles of Human Anatomy and Physiology, 11e 37
