Question 1

Which of the following structures is responsible for producing tears that contain lysozyme, an enzyme that destroys bacteria, and helps lubricate the eye?

Accepted Answer

Lacrimal gland

Question 2

A patient presents with blurry vision due to light focusing as lines rather than points on the retina. Which condition is most likely responsible?

Accepted Answer

Astigmatism

Question 3

Which part of the eye is the only human tissue that can be transplanted without fear of rejection, and why?

Accepted Answer

Cornea, because it lacks blood vessels

Question 4

Which sequence correctly traces the pathway of light through the eye to the point of visual interpretation?

Accepted Answer

Cornea → Lens → Retina → Optic nerve → Thalamus → Occipital lobe

Question 5

Which equation best describes the relationship between the focal length ($$f$$), the object distance ($$d_o$$), and the image distance ($$d_i) $$for the lens of the eye?

Accepted Answer

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

Question 6

A person with an eyeball that is too long experiences blurry vision when looking at distant objects. Which corrective lens should be prescribed?

Accepted Answer

Concave lens for myopia

Question 7

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

Accepted Answer

Crista ampullaris in the semicircular canals

Question 8

Which of the following best explains why the image formed on the retina is upside down and reversed left to right?

Accepted Answer

Refraction of light by the cornea and lens

Question 9

Which of the following is NOT a component of the lacrimal apparatus?

Accepted Answer

Ciliary body

Question 10

A patient is unable to equalize pressure in the middle ear, resulting in discomfort during altitude changes. Which structure is most likely malfunctioning?

Accepted Answer

Pharyngotympanic (auditory) tube

Question 11

Which type of photoreceptor is responsible for vision in dim light and peripheral vision?

Accepted Answer

Rods

Question 12

Which of the following best describes the function of the maculae in the vestibule of the inner ear?

Accepted Answer

Reporting on the position of the head relative to gravity

Question 13

Which of the following is a correct pairing of taste sensation and the chemical it detects?

Accepted Answer

Umami – glutamate

Accepted Answer

Cleanse, protect, moisten, and lubricate the eye

Question 16

Which of the following best describes the pathway of sound vibrations from the external environment to the cochlea?

Accepted Answer

Auricle → External acoustic meatus → Tympanic membrane → Ossicles → Oval window

Question 17

Which of the following is true regarding the development of special senses?

Accepted Answer

Vision requires the most learning after birth

Question 18

Which of the following best describes the function of the optic chiasma?

Accepted Answer

It is where the optic nerves cross, allowing fibers from the medial side of each eye to cross to the opposite side of the brain

Question 19

Which of the following is a likely consequence of presbyopia in older adults?

Accepted Answer

Difficulty focusing on close objects due to decreased lens elasticity

Question 20

Which of the following best explains why a person with sensorineural deafness cannot be helped by a hearing aid?

Accepted Answer

The problem lies in the nervous system structures, not in the conduction of sound
