BIO 152 LAB 4 EXAM 2026 STUDY GUIDE
COMPLETE LAB QUESTIONS AND ANSWERS
100% CORRECT
◉ What three types of receptors respond to stretching, compression,
twisting or other distortions of the cell membrane?
Chemoreceptors, nociceptors, baroreceptors
Nociceptors, gustatory? Receptors, proprioceptors
Tactile recptors, thermoreceptors, olfactory receptors
Proprioceptors, baroreceptors, tactile receptors
Baroreceptors, hair cells, photoreceptors. Answer: Proprioceptors,
baroreceptors, tactile receptors
◉ The division of the autonomic nervous system that maintains
homeostasis during resting conditions is the _________ division.
Answer: Parasympathetic division
,◉ Damage to the stapedius muscle would interfere with the ability
to
Hear loud sounds
Hear high frequency sounds
Hear quiet sounds
Protect the inner ear from damaging prolonged sounds
Hear low frequency sounds. Answer: Protect the inner ear from
damaging prolonged sounds
◉ When all three cone populations are stimulated we see
Red
White
Black
Green
Blue. Answer: white
, ◉ Which of the following is true?
Beta 1 blocking drugs will decrease heart rate and force of heart
contraction
Drugs that block the re-uptake of norepinephrine as synapse
between postganglionic axons abd effectors would reduce
sympathetic activation of effectors
Constriction of the bronchioles of the lung could be increased in
response to either a sympathetic agonist or a parasympathetic
antagonist
Alpha adrenergic receptors are activated by norepinephrine but not
by epinephrine
All of the above are true.. Answer: Beta 1 blocking drugs will
decrease heart rate and force of heart contraction
◉ A reduction in sensitivity in the presence of constant stimulus is
Refraction
Sensory coding
Adaptation
