SUBTOPIC #31: Communication Systems
1) The relaying of mechanical information from the skin (i.e., your sense of touch) is handled by
which major branch of the peripheral nervous system?
A. somatic sensory
B. somatic motor
C. sympathetic branch of the autonomic
D. parasympathetic branch of the autonomic
DIFFICULTY: 3
ANS_KEY: A
EXPL: This is not handled by the autonomic nervous system.
2) If I am attempting to outrun a charging lion, which division of my nervous system will be
putting forth a tremendous effort to regulate the numerous physiological modifications needed to
escape the predator?
A. somatic
B. sympathetic
C. parasympathetic
D. limbic
DIFFICULTY: 4
ANS_KEY: B
EXPL: It is handled by one of the divisions of the autonomic nervous system.
3) The action of the __________ division of the nervous system is dominant during periods of
rest and relaxation, giving it a generally restorative function.
A. somatic
B. sympathetic
C. parasympathetic
D. limbic
DIFFICULTY: 4
ANS_KEY: C
EXPL: It is handled by one of the divisions of the autonomic nervous system.
4) Although there is some overlap between the options listed below, which option best describes
the action of endocrine organs?
A. release of hormones into the bloodstream
B. release of neurotransmitters
C. release of cytokines
D. activation or inhibition of immune cells
DIFFICULTY: 4
ANS_KEY: A
EXPL: Endocrine organs release substances that circulate diffusely throughout the body.
5) Often thought of as the body’s “master gland,” the __________ is the mouthpiece through
which the brain sends numerous hormonal messages to many areas of the body.
A. pancreas
B. thyroid gland
C. pituitary gland
D. pineal gland
DIFFICULTY: 3
ANS_KEY: C
EXPL: This organ sits encased in bone right under the hypothalamus and part of it is even
considered part of the brain proper.
6) The adrenal glands sit atop which organ?
A. heart
B. thyroid
C. liver
D. kidney
DIFFICULTY: 3
ANS_KEY: D
EXPL: The term “renal” refers to the organ itself, and renal failure will give you major problems
with your urinary system.
7) Which of the following is NOT released by the adrenal glands
A. epinephrine
B. norepinephrine
C. acetylcholine
D. cortisol
DIFFICULTY: 3
ANS_KEY: C
EXPL: The correct answer for this question is actually what is released at the neuromuscular
junction.
8) Which of the following would probably NOT show significant increases in production and
release from the endocrine system following a psychological stressor?
A. cortisol
B. melatonin
C. epinphrine
D. norepinephrine
DIFFICULTY: 4
ANS_KEY: B
EXPL: The correct answer for this question is actually released from the small pineal gland
inside the brain.
9) Which general effect best describes the physiological outcome of adrenal hormone release?
A. increased metabolic activity
B. decreased metabolic activity
C. increased release of neurotransmitters
D. decreased release of neurotransmitters
DIFFICULTY: 3
ANS_KEY: A
EXPL: Getting you ready for a perceived emergency is going to cost your body a lot of fuel.
10) Where would you look for your thyroid gland?
A. inside the brain
B. in your abdomen
C. below the larynx (voicebox)
D. below the breastbone
DIFFICULTY: 3
ANS_KEY: C
EXPL: It would certainly not be in your brain or abdomen.
11) Where would you look for your pineal gland?
A. inside the brain
B. in your abdomen
C. below the larynx (voicebox)
D. below the breastbone
DIFFICULTY: 3
ANS_KEY: A
EXPL: This structure calcifies in adults and makes a convenient radiological landmark for people
doing a brain MRI.
12) Of the following communication systems, which is most likely to be involved in your
figuring out the answer to this question?
A. The brain
B. The spinal cord
C. The peripheral nervous system
D. The endocrine system
DIFFICULTY: 2
ANS_KEY: A
EXPL: The brain is responsible for learning, thinking, and language. As such it is probably useful
in answering questions like this one.
13) Of the following communication systems, which is most likely to be involved in detecting
the bug that is crawling up your leg as you read this question?
A. The brain
B. The peripheral nervous system
C. The spinal cord
D. The endocrine system
DIFFICULTY: 2
ANS_KEY: B
EXPL: The somatic nervous system contains nerves that are important for sensory functions,
which include the ability to detect a bug crawling up your leg.
14) Of the following communication systems, which is most likely to control the reflexive
movements of your arms and legs?
A. The brain
B. The peripheral nervous system
C. The spinal cord
D. The endocrine system
DIFFICULTY: 2
ANS_KEY: C
EXPL: The spinal cord controls reflexive movements.
15) Of the following systems, which is primarily responsible for controlling the release of the
hormones that control the release of estrogen and progesterone from the ovaries?
A. The brain
B. The peripheral nervous system
C. The spinal cord
D. The endocrine system
DIFFICUTLY: 2
ANS_KEY: D
EXPL: The endocrine system controls the release of hormones, including estrogen and
progesterone from the ovaries.
16) The pituitary gland regulates
A. the release of many hormones.
B. reflexive movements.
C. conscious movements.
D. response to stress.
DIFFICULTY: 3
ANS_KEY: A
EXPL: The pituitary gland controls the response to stress, but also the release of hormones
associated with growth and fertility.
17) Steroid hormones are related to the hormone _____ and have been linked to _____.
A. testosterone, reduced sensitivity to stress
B. testosterone, aggression
C. estrogen, reduced sensitivity to stress
D. estrogen, reduced aggression
DIFFICULTY: 4
ANS_KEY: B
EXPL: Anabolic steroids, sometimes used by athletes are related to testosterone. Their use has
been linked to increased aggressiveness.
18) The adrenal glands release hormones in response to _____.
A. anger
B. the menstrual cycle
C. stress
D. the release of testosterone
DIFFICULTY: 3
ANS_KEY: C
EXPL: Release of hormones by the adrenal glands has been related to stress.
19. Prolactin is a hormone that is released from the _____ gland that controls the production of
_____.
A. adrenal, adrenalin
B. adrenal, milk
C. pituitary, adrenalin
D. pituitary, milk
DIFFICULTY: 4
ANS_KEY: D
EXPL: Prolactin is a hormone that is necessary for lactation, the production of milk. It is released
by the pituitary gland.
