What is the primary reason junctions in the efferent autonomic pathway are targeted for drug manipulation?
What is the primary reason junctions in the efferent autonomic pathway are targeted for drug manipulation?
- They are resistant to pharmacological effects.
- They function solely in voluntary muscle control.
- They are electrically active sites.
- They allow for chemical transmission. (correct)
Which of the following processes can be affected by drugs targeting neurotransmitter activity?
Which of the following processes can be affected by drugs targeting neurotransmitter activity?
- Neurotransmitter synthesis, storage, release, breakdown, reuptake, and receptor binding (correct)
- Only breakdown and reuptake
- Only receptor binding
- Only neurotransmitter release

Which of the following is a characteristic of drugs affecting the autonomic activity?
- They exclusively enhance neurotransmitter effects.
- They do not affect receptor binding mechanisms.
- They only target the sympathetic nervous system.
- They can either stimulate or inhibit neurotransmitter processes. (correct)

Study Notes
Parasympathetic Nervous System
- Drugs can affect the autonomic nervous system by manipulating neurotransmitter activity at the efferent pathway junctions.
- The steps of neurotransmitter activity (synthesis, storage, release, breakdown, reuptake, receptor binding) can be stimulated or inhibited by drugs.
- Drugs that affect the sympathetic nervous system are also used to manipulate the autonomic nervous system.
Sympathetic Nervous System
- Drugs can target the sympathetic nervous system and cause a wide range of effects.
