Central Nervous System
Central CoreIncludes the Medulla (Breathing)
Cerebellum (Motor coordination), the Thalamus (Relay station), and the
Hypothalamus (Thirst/Hunger/Blood pressure, etc.)

Central Nervous System
Limbic SystemLimbic (Latin for border or belt) Controls
emotional life and memory formation. Includes the Hippocampus, Hypothalamus,
Amydala, septum (pleasure center) and Pituitary glad.

composed of the left and right hemisphere. Contains lobes.

The Nervous System
Peripheral 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
Autonomic “Automatic” 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.

Peripheral Nervous System
Autonomic “Automatic” Nervous System
Parasympathetic Nervous System
Active in relaxed states. Stimulates one organ at a time. Ex: slows heart
rate.
¡Para!=Stop/Slow down
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.
