Correct Answers (Grade A+)
Question 1: What is the autonomic nervous system (ANS)?
Answer: automatic in functions, involuntary actions (heart beat, peristalsis, breathing, glands, etc), divided
into sympathetic and parasympathetic
Question 2: What is the parasympathetic nervous system?
Answer: rest and digest
Question 3: What is the sympathetic nervous system?
Answer: fight or flight
Question 4: What does the adrenergic system also mean?
Answer: sympathetic nervous system
Question 5: What are the primary neurotransmitters for the adrenergic system?
Answer: norepinephrine, epinephrine, and dopamine
Question 6: What is the main purpose of the adrenergic system?
Answer: speeds up physiological reactions
Question 7: What are the receptor sites for the adrenergic system?
Answer: Alpha 1, Alpha 2, Beta 1, Beta 2
Question 8: What does the cholinergic system also mean?
Answer: parasympathetic nervous system
Question 9: What is the primary neurotransmitters for the parasympathetic system?
Answer: acetylcholine
Question 10: What is the main purpose of the cholinergic system?
Answer: slows down physiological responses

, Question 11: What are some sympathetic responses?
Answer: dilated pupils, dilated bronchioles, increased heart rate, constricted blood vessels, decreased
peristalsis, relaxed bladder, relaxed uterine muscle
Question 12: What are some parasympathetic responses?
Answer: constricted pupils, constricted bronchioles and increased secretions, decreased heart rate, dilated
blood vessels, increased peristalsis, constricted bladder, increased salvation
Question 13: What happens when Alpha 1 adrenergic receptors are stimulated during a sympathetic
reaction?
Answer: - ‘ HR - ‘ BP - ‘ blood return to heart - “ salivary secretions - ‘ bladder relaxation - ‘ urinary
sphincter contraction dilation of pupils
Question 14: What happens when Alpha 2 adrenergic receptors are stimulated during a sympathetic
reaction?
Answer: “ BP “ GI motility and tone
Question 15: mydriatic
Answer:
Question 16: miotic
Answer:
Question 17: What happens when Beta 1 adrenergic receptors are stimulated during a sympathetic
reaction?
Answer: heart - norepinephrine, epinephrine, and dopamine released - ‘ cardiac contractility - ‘ HR - ‘ BP - ‘
introcular pressure
