Chapter 16: Autonomic Nervous System and Higher-Order Functions

Question 1

Alpha1 -receptor agonists

Answer 1

Drugs used to treat hypotension (low BP) by stimulating A1 receptors to cause vasoconstriction of blood vessels.

Question 2

Alpha2 -receptor agonists

Answer 2

Drugs used to treat hypertension (high BP) by stimulating A2-adrenergic receptors to inhibit sympathetic vasomotor centers.

Question 3

Beta-adrenergic Blockers

Answer 3

Drugs that decrease HR and force a contraction, lowering peripheral BP by acting on beta-adrenergic receptors to diminish the effects of epinephrine.

Question 4

Parasympathetic Blocking Agents

Answer 4

Drugs that target muscarinic receptors at neuromuscular or neuroglandular junctions.

Question 5

Parasympathomimetic Drugs

Answer 5

Drugs that mimic parasympathetic stimulation and increase the activity along the digestive tract.

Question 6

Sympathetic Blocking Agents

Answer 6

Drugs that bind to receptors sites, preventing a normal response to neurotransmitters or sympathomimetic drugs.

Question 7

Sympathomimetic Drugs

Answer 7

Drugs that mimic the effects of sympathetic stimulation.
