and Answers 2023
1) Which of the following statements is inaccurate with respect to the sensory
system of
katydids?
A) Katydids' ears are located in the bend on their front legs.
B) Katydids have excellent hearing.
C) Katydids' hearing is used to identify mating calls of members of their own
species.
D) Katydids cannot detect any echolocation sounds made by different species,
such as
bats.
D) Katydids cannot detect any echolocation sounds made by different species, such as
bats.
All sensory systems work in the same general way. They transduce an incoming
stimulus
into changes in membrane
A) potential.
B) capacitance.
C) refractory period.
D) fluidity.
A) potential.
Which of the following is NOT one of the steps of sensory processing?
A) transduction of the signal
B) transmission of the signal to the integrating center
C) perception of the stimulus at the integrating center
D) motor response to the signal
D) motor response to the signal
What defines a cell as an afferent neuron?
A) It has the capacity to respond to environmental stimuli.
B) It is located at the periphery.
C) It has an axon that carries information to integrating centers.
D) It has receptor proteins in its membrane.
C) It has an axon that carries information to integrating centers
When a sensory receptor is an afferent neuron, the membrane potential that is
initiated by a
stimulus is called a
A) generator potential.
B) receptor potential.
C) synaptic potential.
D) action potential.
A) generator potential.
A sensory illusion called paradoxical cold happens when a point heat stimulus is
applied to a
, cold patch of skin, and is perceived as cold, not hot. This illusion happens due to
A) labeled-line pathways.
B) population coding.
C) both heat and cold receptors on the same sensory neuron.
D) lateral inhibition.
A) labeled-line pathways.
7) Select the pair below that does not match.
A) chemoreceptors - detect chemicals
B) photoreceptors - detect light
C) mechanoreceptors - detect magnetic fields
D) thermoreceptors - detect temperature
C) mechanoreceptors - detect magnetic fields
For sensory receptor cells, the "threshold of detection" is the weakest stimulus
that produces
A) a response.
B) a response 50 percent of the time.
C) a response 100 percent of the time.
D) a maximum response magnitude.
B) a response 50 percent of the time.
In the strategy named "range fractionation,"
A) individual receptor cells are sensitive to a small portion of the possible range
of
intensities, but multiple receptors cover different parts of the range.
B) individual receptor cells are sensitive to a large portion of the possible range
of
intensities.
C) there is a decrease in sensory discrimination.
D) populations of receptors hinder sensory discrimination.
A) individual receptor cells are sensitive to a small portion of the possible range of
intensities, but multiple receptors cover different parts of the range.
Advantages of populations of receptors, as opposed to individual receptors,
include
A) improved sensory discrimination.
B) improved stimulus intensity.
C) improved signal firing rate.
D) all of the above
A) improved sensory discrimination.
When a stimulus is continually applied but the action potential frequency
declines, this is called
A) receptor attenuation.
B) receptor acclimation.
C) receptor accommodation.
D) receptor adaptation.
D) receptor adaptation
In aquatic vertebrates, gustation always involves detecting sensations involved
