Questions and Verified Answers | UTA | A+ Graded
1. The autonomic nervous system sympathetic branch primarily regulates which of the following?
A. Digestion and rest
B. Cardiovascular system, body temperature, and fightorflight response
C. Pupil constriction and salivation
D. Bladder emptying and bowel movements
Answer: B. Cardiovascular system, body temperature, and fightorflight response
Explanation: The sympathetic nervous system prepares the body for "fight or flight" by increasing heart
rate, redistributing blood flow, and regulating body temperature.
2. Which neurotransmitters are mediated by the sympathetic nervous system?
A. Acetylcholine and serotonin
B. Norepinephrine, epinephrine, and dopamine
C. GABA and glutamate
D. Histamine and substance P
Answer: B. Norepinephrine, epinephrine, and dopamine
Explanation: The sympathetic nervous system primarily uses norepinephrine, epinephrine, and
dopamine as its neurotransmitters.
,3. An adrenergic antagonist functions by:
A. Turning on the fightorflight response
B. Blocking or turning off adrenergic receptor activity
C. Stimulating parasympathetic activity
D. Increasing acetylcholine release
Answer: B. Blocking or turning off adrenergic receptor activity
Explanation: Adrenergic antagonists block adrenergic receptors, effectively turning off or reducing
sympathetic nervous system activity.
4. An adrenergic agonist that promotes fightorflight response functions by:
A. Blocking adrenergic receptors
B. Turning on or stimulating adrenergic receptors
C. Inhibiting norepinephrine release
D. Activating muscarinic receptors
Answer: B. Turning on or stimulating adrenergic receptors
Explanation: Adrenergic agonists activate adrenergic receptors, stimulating the fightorflight response.
5. The four types of adrenergic receptors are:
A. Alpha 1, alpha 2, beta 1, and beta 2
B. Muscarinic, nicotinic, dopaminergic, and serotonergic
C. Alpha 1, beta 1, gamma, and delta
,D. H1, H2, M1, and M2
Answer: A. Alpha 1, alpha 2, beta 1, and beta 2
Explanation: Adrenergic receptors include alpha1, alpha2, beta1, and beta2 subtypes, each mediating
different physiological responses.
6. Stimulation of alpha1 adrenergic receptors results in:
A. Bronchodilation and uterine relaxation
B. Vasoconstriction, ejaculation, and contraction of bladder neck and prostate
C. Increased heart rate and AV node conduction
D. Glycogenolysis and vasodilation
Answer: B. Vasoconstriction, ejaculation, and contraction of bladder neck and prostate
Explanation: Alpha1 receptor activation causes vasoconstriction, ejaculation, and contraction of the
bladder neck and prostate.
7. Alpha2 adrenergic receptors have which clinical significance?
A. Major role in bronchodilation
B. Minimal clinical significance
C. Primary role in heart rate regulation
D. Key role in uterine contraction
Answer: B. Minimal clinical significance
, Explanation: Alpha2 adrenergic receptors have minimal clinical significance compared to other
adrenergic receptor subtypes.
8. Beta1 adrenergic receptor stimulation causes:
A. Vasodilation and bronchial dilation
B. Increased heart rate, increased force of contraction, and AV node conduction velocity
C. Glycogenolysis and uterine relaxation
D. Pupil dilation and decreased gastric secretions
Answer: B. Increased heart rate, increased force of contraction, and AV node conduction velocity
Explanation: Beta1 receptors increase heart rate, contractile force, and AV node conduction velocity,
and stimulate renin release from the kidneys.
9. Beta2 adrenergic receptor stimulation results in:
A. Vasoconstriction and increased heart rate
B. Bronchial dilation, uterine muscle relaxation, vasodilation, and glycogenolysis
C. Ejaculation and bladder neck contraction
D. Pupil constriction and increased salivation
Answer: B. Bronchial dilation, uterine muscle relaxation, vasodilation, and glycogenolysis
Explanation: Beta2 receptor activation causes bronchodilation, uterine relaxation, vasodilation, and
glycogenolysis.
