Study Notes
Autonomic Nervous System
- The autonomic nervous system controls involuntary functions like heart rate, digestion, and breathing.
- It has two branches: sympathetic and parasympathetic.
Sympathetic Nervous System
- Effects: Speeds heartbeat, dilates pupils, inhibits salivation, stimulates sweating, constricts blood vessels in skin, stimulates glucose release.
-
Effects on organs:
- Lungs: Constrict airways.
- Heart: Speeds heartbeat.
- Liver: Stimulates glucose release.
- Pancreas: In details, the sympathetic nervous system doesn't directly stimulate the pancreas. It inhibits the digestive system.
- Stomach: Inhibits digestive system.
- Intestines: Inhibits digestive system.
- Bladder: Contracts bladder.
- Genitals: Stimulates sexual arousal.
- Neurotransmitters: Releases epinephrine (adrenaline) and norepinephrine.
Parasympathetic Nervous System
- Effects: Slows heartbeat, constricts pupils, stimulates salivation, stimulates digestive system, relaxes bladder.
-
Effects on organs:
- Lungs: Constrict airways.
- Heart: Slows heartbeat.
- Stomach: Stimulates digestive system.
- Intestines: Stimulates digestive system.
- Bladder: Relaxes bladder.
- Genitals: Stimulates orgasm.
- Neurotransmitters: Epinephrine and norepinephrine.
