LAB ASSESSMENT QUESTIONS AND
SOLUTIONS VERIFIED
◉ Which of the following is not one of the six primary taste
sensations?
A. umami
B. salty
C. sour
D. peppery
E. sweet. Answer: D. peppery
◉ The ________ convey(s) information about head position with
respect to gravity.
A. cochlea
B. utricle
C. ampulla
D. saccule
E. utricle and the saccule. Answer: E. utricle and the saccule
,◉ Olfactory information is sent to all of the following areas EXCEPT
the __________.
A. thalamus
B. limbic system
C. olfactory cortex
D. hypothalamus. Answer: A. thalamus
◉ Movement of the endolymph in the semicircular canals:
A. signals linear acceleration.
B. signals rotational movements.
C. allows us to hear low tones.
D. produces a rushing sound.
E. signals body position with respect to gravity.. Answer: B. signals
rotational movements
◉ A sensory receptor characterized as a free nerve ending using the
neurotransmitter, Substance P, would most likely be a:
Mechanoreceptor
Thermoreceptor
,Nociceptor
Photoreceptor
chemoreceptor. Answer: Nociceptor
◉ Which of the following statements about hair cells is false?
A. Hair cells within the organ of corti respond when pushed against
the tectorial membrane
B. Hair cells in the Uricle and saccule are activated by rotational
movements.
C. Hair cells are embedded in a gelatinous mass called the cupula
within the semicircular ducts
D. Hair cells are mechanoreceptors
E. Hair cells depolarize as mechanically-gated potassioum channels
open and potassium enters the cell.. Answer: B. Hair cells in the
Uricle and saccule are activated by rotational movements.
◉ Which of the following is FALSE?
Pressure waves in the perilymph are produced by the in/out
movements of the oval window
A sound with a high frequency of 16,000hz would cause vibration of
the organ of corti near the far end of the cochlear duct.
, The tympanic membrane and auditory ossicles amplify sound wave
vibrations
Higher intensity sounds are perceived as louder because they cause
larger amplitude vibrations of the organ or corti and stimulate more
hair cells.
All of the above are false.. Answer: A sound with a high frequency of
16,000hz would cause vibration of the organ of corti near the far end
of the cochlear duct.
◉ Which of the following statements about tonic receptors and
phasic receptors is TRUE?
Both tonic and phasic recptors are active only when a change occurs
in the stimulus being monitored
A phasic receptor remains active as long as the stimulus is present
while a tonic receptor is active only when a change occurs in the
stimulus being monitored.
A tonic receptor remains active as long as the stimulus is present
while a phasic receptor is active only when a change occurs in the
stimulus being monitored.
