EXAM 4 PRACTICE, BIOL 223A
UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS
Question 1.
Which of the following is TRUE?
Aspirin and ibuprophen are examples of non-steroidal anti inflammatory drugs that block central
nervous system pain pathways
Anesthetics are drugs that block pain without affecting perception of other sensations
Analgesics are drugs that block both pain and the perception of other sensations
Morphine and demetrol (opiate drugs) work by blocking central nervous system pain pathways
All of the above are true
ANSWER
Morphine and demetrol (opiate drugs) work by blocking central nervous system pain pathways
Question 2.
Drugs that mimic the effects of epinephrine might be used to:
Decrease sweat production
Increase gastric motility
Dilate bronchioles
Decrease blood pressure
Decrease heart rate
ANSWER
Dilate bronchioles
,Question 3.
Which of the following statements about hearing is FALSE?
The round window separates perilymph of the inner ear from air cavity of the middle ear
The primary auditory cortex is tenotopically organized
The organ of corti hair cells are located on the basilar membrane
The tensor? Tympanic muscle contracts to assist with hearing low volume sounds
The primary auditory cortex is located on the superior surface of the temporal lobe
ANSWER
The tensor? Tympanic muscle contracts to assist with hearing low volume sounds
*The tensor tympani muscle reacts to sudden loud sounds*
Question 4.
Which of the following would be an example of cortisol?-level conscious processes influencing
autonomic function?
Increased heart rate when you see a person that you dislike
A violent coughing attack in response to an irritant
Dilation of airways when blood levels of carbon dioxide are higher than normal
increased heart rate when you walk up a hill
dilation of the pupils of the eye when you enter a dark room.
ANSWER
Increased heart rate when you see a person that you dislike
, Question 5.
When ingested in large enough amounts, muscarine is poisonous because:
It produces excessive activity in effectors of the sympathetic division of the ANS but has little effect on
effectors of the parasympathetic division
It produces excessive activity in effectors of the sympathetic division of the ANS and greatly decreased
activity in effectors of the parasympathetic division.
It produces excessive activity in effectors of the parasympathetic division of the ANS but has little effect
on effectors of the sympathetic division.
It produces greatly decreased activity in effectors of both the sympathetic and parasympathetic
divisions o the ANS
It produces excessive activity in the effectors of both the sympathetic and parasympathetic divisions of
the ANS
ANSWER
It produces greatly decreased activity in effectors of both the sympathetic and
parasympathetic divisions o the ANS
Question 6.
Sounds have different tones due to different frequencies of the sound waves. The auditory sense is
able to provide information to the CNS about different sound wave frequencies because
Different regions of the basilar membrane vibrate with different frequencies
Different regions of the tectorial membrane vibrate with different frequencies
Sound waves cause the hairs (cilia) of all the hair cells in the Organ of Corti to vibrate, and the rate of
hair cell vibration differs, corresponding to different sound wave frequencies
Sound waves cause pressure waves in the perilymph which cause the round window to vibrate and the
hair cells on the round window maculae area detects the different sound wave frequencies
Different regions of the tympanic membrane between the outer and middle ear vibrate with different
frequencies
ANSWER
Different regions of the basilar membrane vibrate with different frequencies
