Question 1

Which of the following best describes the process of sensory transduction?

Accepted Answer

The conversion of a stimulus into a nerve signal (electrical impulse)

Question 2

A patient is unable to distinguish between hot and cold objects placed on their skin. Which type of sensory receptor is most likely impaired?

Accepted Answer

Thermoreceptors

Question 3

Which of the following is an example of an exteroceptor?

Accepted Answer

A receptor in the skin that detects pressure

Question 4

Which statement best distinguishes between sensation and perception?

Accepted Answer

Sensation is the awareness of a stimulus, while perception is the interpretation of what the stimulus means.

Question 5

Which of the following best explains why the fingertips are more sensitive to touch than the back?

Accepted Answer

Fingertips have a higher density of mechanoreceptors with smaller receptive fields.

Question 6

A person is able to feel the initial touch of their shirt but quickly stops noticing it. Which type of receptor is responsible for this adaptation?

Accepted Answer

Phasic receptor

Question 7

Which of the following is a correct pairing of receptor type and stimulus?

Accepted Answer

Photoreceptor – light energy

Question 8

Which structure is classified as a nonencapsulated sensory receptor?

Accepted Answer

Merkel disc

Question 9

A patient has difficulty sensing the position of their limbs in space. Which receptor type is most likely affected?

Accepted Answer

Proprioceptors

Question 10

Which of the following best describes the function of Pacinian (lamellated) corpuscles?

Accepted Answer

Detect deep pressure and vibrations

Question 11

If a stimulus is applied to a large receptive field, what is the likely outcome?

Accepted Answer

The perception of the stimulus will be less precise.

Question 12

Which of the following best describes tonic receptors?

Accepted Answer

They adapt slowly or not at all to a constant stimulus.

Question 13

A person is exposed to a strong odor, but after a few minutes, they no longer notice it. This is an example of:

Accepted Answer

Sensory receptor adaptation

Question 14

Which of the following equations best represents the relationship between stimulus intensity ($$I) $$and frequency of action potentials ($$f) in a $$sensory neuron?

Accepted Answer

$$f \propto I$$

Question 15

Which of the following is true regarding the distribution of general and special senses?

Accepted Answer

General senses are distributed throughout the body, while special senses are limited to the head.

Question 16

Which of the following best explains why a person can feel a mosquito landing on their arm but not on their back?

Accepted Answer

The arm has a higher density of cutaneous receptors with smaller receptive fields.

Question 17

Which of the following is a function of Ruffini (bulbous) corpuscles?

Accepted Answer

Detect deep pressure and skin stretching

Question 18

Which of the following best describes the role of receptive fields in sensory perception?

Accepted Answer

They determine the spatial resolution and precision of stimulus detection.

Question 19

A patient reports a loss of pain sensation in a specific area of skin. Which type of receptor is most likely damaged?

Accepted Answer

Nociceptor

Question 20

Which of the following best describes the function of Meissner (tactile) corpuscles?

Accepted Answer

Detect touch and vibrations in hairless skin
