Question 1

Which of the following best describes the difference between rods and cones in the retina?

Accepted Answer

Rods function best in low light and are sensitive to movement, while cones are responsible for color vision and visual acuity.

Question 2

Which of the following is NOT considered one of the five special senses?

Accepted Answer

Touch

Question 3

Accommodation of the eye involves which of the following physiological changes?

Accepted Answer

Relaxation of the ciliary muscles to flatten the lens for distant vision

Question 4

How is the image formed on the retina different from the actual object?

Accepted Answer

The image is inverted and smaller than the object.

Question 5

Which pathway correctly describes the transmission of impulses from the retina to visual interpretation?

Accepted Answer

Retina → Optic nerve → Thalamus → Occipital lobe

Question 6

Visual fields from each eye overlap to provide depth perception. What is this phenomenon called?

Accepted Answer

Binocular vision

Question 7

A patient is diagnosed with myopia. Which of the following best describes this condition and its correction?

Accepted Answer

Light focuses in front of the retina; corrected with concave lenses.

Question 8

Which of the following occurs during hyperopia (farsightedness) and how is it corrected?

Accepted Answer

Light focuses behind the retina; corrected with convex lenses.

Question 9

Which of the following is an example of a photopupillary reflex?

Accepted Answer

Constriction of the pupil in response to bright light

Question 10

Which two senses are processed by the ears?

Accepted Answer

Hearing and equilibrium

Question 11

What is the primary function of the macula in the eye?

Accepted Answer

Providing sharp, detailed central vision

Question 12

Which structure in the inner ear is responsible for detecting rotational movements of the head?

Accepted Answer

Crista ampullaris

Question 13

The spiral organ of Corti is essential for which sensory function?

Accepted Answer

Hearing

Question 14

How does the basilar membrane perceive different pitches?

Accepted Answer

High-frequency sounds vibrate the base, while low-frequency sounds vibrate the apex.

Question 15

A patient presents with loss of peripheral vision but intact central vision. Which retinal cells are most likely affected?

Accepted Answer

Rods

Question 16

Which equation best represents the relationship between lens curvature and focal length in the eye?

Accepted Answer

$f = \frac{1}{P}$

Question 17

During the accommodation reflex, which structure changes shape to focus on near objects?

Accepted Answer

Lens

Question 18

Which of the following best explains why depth perception is impaired in individuals with strabismus (misalignment of the eyes)?

Accepted Answer

The lack of overlapping visual fields prevents proper binocular vision.

Question 19

Which reflex is responsible for maintaining focus on a moving object by adjusting the angle of the eyes?

Accepted Answer

Convergence reflex

Question 20

A patient with damage to the occipital lobe would most likely experience deficits in which sensory function?

Accepted Answer

Vision
