Accepted Answer

Referred pain

Question 3

Which of the following best explains why olfactory receptors adapt quickly to continuous odors?

Accepted Answer

Sensory adaptation reduces the frequency of action potentials in response to a constant stimulus

Question 4

Which structure in the ear is responsible for detecting rotational or angular motion, such as spinning?

Accepted Answer

Semicircular canals

Question 5

A person steps on a sharp object and immediately withdraws their foot. Which type of receptor is most directly involved in this response?

Accepted Answer

Question 6

Which of the following statements about mechanoreceptors is correct?

Accepted Answer

They respond to mechanical stimuli such as pressure, touch, and stretch

Question 7

If the frequency of action potentials sent to the brain increases, what does this most likely indicate about the stimulus?

Accepted Answer

The stimulus intensity has increased

Question 8

Which equation best represents the relationship between stimulus intensity ($$I) $$and frequency of action potentials ($$f) $$generated by sensory receptors?

Accepted Answer

$$f = k 	imes I$$
