Central Nervous System Peripheral Nervous System The Nervous System Somatic Nervous System Autonomic Nervous System Sympathetic Nervous System Parasympathetic Nervous System
Peripheral Nervous System The Nervous System Somatic Nervous System Transmits information about external stimulation from (senses) skin, muscles and joints to the Central Nervous System. Controls our voluntary movements.
Peripheral Nervous System The Nervous System Sympathetic Nervous System Autonomic “Automatic” Nervous System Parasympathetic Nervous System
Peripheral Nervous System The Nervous System Sympathetic Nervous System Active in emotional or excited states. Works as a unit. When you are excited your pupils dilate, heart speeds up, you perspire, etc. Autonomic “Automatic” Nervous System
Peripheral Nervous System The Nervous System Parasympathetic Nervous System Active in relaxed states. Stimulates one organ at a time. Ex: slows heart rate. ¡Para!=Stop/Slow down Autonomic “Automatic” Nervous System
Please explain which part of the autonomic nervous system (either parasympathetic or sympathetic) is at work in the following scene: • Over the past several months you have applied to several colleges. As you approached the mailbox yesterday you saw a letter from DePaul University. (Your top choice for school.) Your heart started to race, your palms began to sweat, and your pupils dilated. Finally, you managed to get the letter open. You were accepted! Eventually your heart rate decreased and your pupils returned to their normal state and you quit sweating.
