Question 1

Which type of sensory receptor is primarily responsible for detecting changes in blood pH levels?

Accepted Answer

Chemoreceptors

Question 2

A patient presents with an inability to distinguish between salty and sour tastes. Which structure is most likely affected?

Accepted Answer

Taste buds

Question 3

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

Accepted Answer

$$f = \frac{I}{k}$$, where $$k is a $$constant

Question 4

Which of the following best explains why adaptation occurs in sensory receptors?

Accepted Answer

Receptors reduce their sensitivity to constant stimuli to prevent overload

Question 5

A person is unable to detect vibration but can still feel pressure and pain. Which receptor type is most likely dysfunctional?

Accepted Answer

Tactile receptors

Question 6

Which structure in the eye is responsible for focusing light onto the retina?

Accepted Answer

Lens

Question 7

If a patient has difficulty maintaining balance after an inner ear infection, which structure is most likely affected?

Accepted Answer

Vestibular apparatus

Question 8

Which of the following best describes the function of nociceptors?

Accepted Answer

Detect pain from physical or chemical damage

Question 9

A patient is unable to distinguish between red and green colors. Which photoreceptor type is most likely affected?

Accepted Answer

Red or green cones

Question 10

Which equation describes the process of accommodation in the eye, where the focal length ($$f) of $$the lens changes to focus on near objects?

Accepted Answer

$$f = \frac{r}{2}$$, where $$r is $$the radius of curvature of the lens

Question 11

Which of the following is NOT a special sense?

Accepted Answer

Touch

Question 12

Which structure in the ear is responsible for transmitting vibrations from the tympanic membrane to the inner ear?

Accepted Answer

Olfactory bulb

Question 14

Which of the following best describes the role of the Golgi tendon organ?

Accepted Answer

Monitors muscle tension

Question 15

Which sensory receptor type is most likely to be activated when you step on a sharp object?

Accepted Answer

Nociceptors

Question 16

Which of the following is a function of the vascular tunic of the eye?

Accepted Answer

Regulates the amount of light entering the eye

Question 17

Which equation best represents the calculation of visual acuity ($$VA) $$given the distance at which a person can read a standard line ($$d) $$and the distance at which a normal person can read the same line ($$D$$)?

Accepted Answer

$$VA = \frac{d}{D}$$

Question 18

Which of the following best explains why older adults may experience a decline in taste sensitivity?
