Question 1

Which of the following best describes receptor adaptation in the context of general sense receptors?

Accepted Answer

Receptors decrease their response to a constant stimulus over time.

Question 2

A patient reports feeling pain in their left arm during a heart attack. This phenomenon is best explained by which concept?

Accepted Answer

Referred pain

Question 3

Which type of receptor is responsible for detecting changes in muscle length and joint position?

Accepted Answer

Proprioceptors

Question 4

What is the main difference between tonic and phasic receptors?

Accepted Answer

Tonic receptors provide constant information, while phasic receptors respond to changes.

Question 5

Pain receptors are classified as which type of adapting receptor?

Accepted Answer

Slow adapting (tonic)

Question 6

Which of the following best describes the process of olfactory adaptation?

Accepted Answer

Olfactory receptors decrease their response to a persistent odor.

Question 7

Which cells in the retina are primarily responsible for color vision?

Accepted Answer

Cones

Question 8

A person is unable to see objects clearly at close range. Which process is most likely impaired?

Accepted Answer

Accommodation

Question 9

Which equation best represents the relationship between focal length ($$f$$), object distance ($$d_o$$), and image distance ($$d_i) in $$the eye's lens?

Accepted Answer

$$\frac{1}{f} = \frac{1}{d_o} + \frac{1}{d_i}$$

Question 10

Question 14

Which photoreceptor is most sensitive to dim light?

Accepted Answer

Rods

Question 15

Which of the following best explains why the blind spot exists in the human eye?
