  2. Which of the following is NOT an antagonistic effect of the sympathetic nervous system?

    A. dilated airways
    B. increased cognitive functioning
    C. increased heart rate
    D. inhibited digestion and elimination
    B. increased cognitive functioning
  3. Which autonomic neurons release norepinephrine as a neurotransmitter?

    A. sympathetic postganglionic neurons
    B. parasympathetic preganglionic neurons
    C. sympathetic preganglionic neurons
    D. parasympathetic postganglionic neurons
    A. sympathetic postganglionic neurons
  4. For which of the following activities is the parasympathetic nervous system generally responsible?

    A. resting and digesting
    B. vigorous physical activity
    C. fight-or-flight responses
    D. sweating and dilating pupils
    A. resting and digesting
  5. Symptoms of autonomic neuropathy could include any EXCEPT which of the following?

    A. diarrhea
    B. constipation
    C. abnormal stretch reflex responses
    D. hyposecretion by sudoriferous glands
    C. abnormal stretch reflex responses
  6. Which of the following is a way in which the somatic and autonomic nervous systems are similar?

    A. Both systems share common effectors.
    B. Both systems elicit the same target organ responses to their neurotransmitters.
    C. Both systems have ganglia in their motor pathways.
    D. Both systems share common efferent pathways.
    E. None of the above.
    E. None of the above.
  7. Which of the following best demonstrates an example of cooperation of the parasympathetic and sympathetic nervous systems?

    A. Parasympathetic stimulation causes copious sweating; sympathetic stimulation causes epidermal pores to dilate.
    B. Sympathetic stimulation causes vasodilation of blood vessels in the clitoris, leading to erection; parasympathetic stimulation then causes reflex contractions of the vagina.
    C. Sympathetic stimulation causes vasodilation of blood vessels in the penis, leading to erection; parasympathetic stimulation then causes ejaculation.
    D. Parasympathetic stimulation causes vasodilation of blood vessels in the penis, leading to erection; sympathetic stimulation then causes ejaculation.
    D. Parasympathetic stimulation causes vasodilation of blood vessels in the penis, leading to erection; sympathetic stimulation then causes ejaculation.
