Study Notes
The Somatic Nervous System
- Mediates voluntary movement
The Autonomic Nervous System
- Regulates involuntary bodily functions such as heart rate, digestion, and respiration
- Divided into the sympathetic and parasympathetic nervous systems
Sympathetic Nervous System
- Responsible for the 'fight or flight' response
- Increases heart rate and blood pressure
- Diverts blood flow away from the digestive system and towards the muscles
- Releases the neurotransmitters epinephrine (adrenaline) and norepinephrine (noradrenaline) during the 'fight or flight response'
Parasympathetic Nervous System
- Responsible for calming the body and conserving energy
- Decreases heart rate and blood pressure
- Primary neurotransmitter is acetylcholine
Parasympathomimetic Drugs
- Mimic the effects of the parasympathetic nervous system
- Promote relaxation and decrease heart rate

Description
Test your knowledge of cholinergic drugs, neurotransmitters, and the structure-activity relationships of acetylcholine in the nervous system. This quiz covers the biosynthesis and metabolism of acetylcholine, as well as the introduction of the nervous system and parasympathomimetic drugs.
