Question 1

Which of the following best describes the function of mechanoreceptors in the peripheral nervous system?

Accepted Answer

They respond to touch, pressure, vibrations, and stretch.

Question 2

A patient presents with loss of proprioception. Which type of receptor is most likely affected?

Accepted Answer

Proprioceptors

Question 3

Which of the following is NOT a way to classify sensory receptors?

Accepted Answer

Rate of neurotransmitter release

Question 4

Which receptor type is primarily responsible for detecting temperature changes?

Accepted Answer

Thermoreceptors

Question 5

A person feels pain in their left arm during a heart attack. This is an example of:

Accepted Answer

Referred pain

Question 6

Which of the following best describes the difference between phasic and tonic receptors?

Accepted Answer

Phasic receptors adapt quickly and report changes, while tonic receptors adapt slowly or not at all.

Question 7

Which of the following structures is NOT part of a typical peripheral nerve?

Accepted Answer

Epimysium

Question 8

Which cranial nerve is primarily responsible for controlling most of the eye muscles?

Oculomotor nerve

Question 9

Which of the following is TRUE regarding the classification of peripheral nerves?

Accepted Answer

Peripheral nerves can be classified as sensory, motor, or mixed.

Question 10

Which of the following is a function of the vagus nerve?

Accepted Answer

Transmits sensory information from the thoracic and abdominal viscera

Question 11

Which of the following best explains the role of nociceptors?

Accepted Answer

They respond to pain and warn of possible tissue damage.

Question 12

Which of the following is an example of an encapsulated receptor?

Accepted Answer

Tactile (Meissner's) corpuscles

Question 13

Which process occurs at the receptor level of sensory integration?

Accepted Answer

Initiation of graded potential and generation of action potential

Question 14

Which of the following is TRUE about referred pain?

Accepted Answer

It occurs because visceral and somatic afferent pathways are shared.

Question 15

Which equation best represents the relationship between graded potential ($$V_{GP}) $$and action potential threshold ($$V_{th}) at $$the receptor level?

Accepted Answer

$$V_{GP} \geq V_{th}$$

Question 16

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

Accepted Answer

Thermoreceptors - temperature

Question 17

Which of the following statements about the structure of a nerve is correct?

Accepted Answer

The epineurium encloses the entire nerve.

Question 18

Which of the following is a function of the trigeminal nerve?

Accepted Answer

Controls muscles of mastication and transmits facial sensation

Question 19

Which of the following best describes the role of endogenous opioids in pain modulation?

Accepted Answer

They change the perception of pain by inhibiting pain pathways.

Question 20

Which of the following is TRUE regarding the processing of sensory information at the perceptual level?

Accepted Answer

It interprets sensory information based on location where it was received.
