Question 1

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

Accepted Answer

The conversion of a stimulus into an action potential by a sensory receptor.

Question 2

A patient reports feeling pain in their left arm during a heart attack, even though the arm is uninjured. This phenomenon is known as:

Accepted Answer

Referred pain

Question 3

Which of the following statements about receptor specificity is correct?

Accepted Answer

A receptor's sensitivity is determined by the type of stimulus it detects.

Question 4

Which mechanoreceptor is responsible for detecting deep pressure and high-frequency vibration?

Accepted Answer

Pacinian (lamellated) corpuscle

Question 5

A person is exposed to a constant, unchanging stimulus and gradually stops noticing it. This process is called:

Accepted Answer

Adaptation

Question 6

Which type of sensory receptor is primarily responsible for detecting changes in blood pressure within arteries?

Accepted Answer

Baroreceptors

Question 7

Which of the following best explains why the brain interprets rubbing your eyes as flashes of light?

Accepted Answer

The labeled line from the retina always signals light, regardless of the actual stimulus.

Question 8

Which of the following is TRUE regarding tonic and phasic receptors?

Accepted Answer

Phasic receptors are fast-adapting and respond to changes in stimulus intensity.

Question 9

A person steps on a sharp object and immediately withdraws their foot. Which type of nerve fiber is primarily responsible for the rapid transmission of this pain signal?

Accepted Answer

Type A fibers

Question 10

Which of the following best describes the function of proprioceptors?

Accepted Answer

Providing information about body position and movement

Question 11

Which of the following is NOT a general sense?

Accepted Answer

Balance

Question 12

Which mechanoreceptor is most likely to be activated when you feel a gentle breeze moving the hair on your arm?

Accepted Answer

Root hair plexus

Question 13

Which of the following best describes the difference between peripheral adaptation and central adaptation?

Accepted Answer

Peripheral adaptation reduces receptor sensitivity, while central adaptation inhibits sensory pathways in the CNS.

Question 14

Which of the following is TRUE about chemoreceptors in the carotid and aortic bodies?

Accepted Answer

They detect changes in the concentration of O$$_2$$, CO$$_2$$, and other chemicals in the blood.

Question 15

A patient with an amputated leg reports feeling pain in the missing limb. This is an example of:

Accepted Answer

Phantom limb pain

Question 16

Which of the following best explains why abdominal pain is often difficult to localize?

Accepted Answer

Abdominal nociceptors have large receptive fields.

Question 17

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

Accepted Answer

Nociceptor – tissue damage

Question 18

Which of the following best describes the role of the firing pattern of action potentials in sensory interpretation?

Accepted Answer

It determines the type, intensity, and duration of the stimulus.

Question 19

Which of the following mechanoreceptors is most important for detecting stretching of the skin?

Accepted Answer

Ruffini's corpuscle

Question 20

Which of the following is TRUE regarding the conscious awareness of changes in blood chemistry detected by visceral chemoreceptors?

Accepted Answer

Visceral chemoreceptors do not communicate with the cerebral cortex, so we are not consciously aware of these changes.
