BSC2346 Human Anatomy and Physiology

Module 09 Quiz

Question 1

The sclera is part of which layer of the eye?

Answers:

Fibrous layer

Inner layer

Vascular layer

It is not associated with a layer of the eye

Question 2

Olfactory tract damage would affect which of your special senses?

Answers:

Sight

Taste

Smell

Hearing

Question 3

Movement of the cupula within the semicircular canals initiates the detection of acceleration or de-acceleration by moving the sensory hair cells.

Answers:

True

False

Question 4

Which statement is true regarding vision and eye anatomy?

Answers:

The rod cells are involved in color vision and cones are involved in black and white vision

The cornea changes thickness to appropriately refract light coming into the eye

The lacrimal gland is responsible for producing tears to cleanse and lubricate the eye surface

The vitreous humor (body) is located anterior to the lens

Question 5

What statement is true regarding the eye?

Answers:

The fovea centralis of the macula lutea has the highest concentration of rod cells

The muscles of the eye are all controlled by peripheral nerves

The ciliary processes of the eye secrete the fluid that fills that anterior chamber of the eye

The fovea centralis is the blind spot of the eye

Question 6

Gustation is the medical term that refers to the sense of smell.

Answers:

True

False

Question 7

Myopia occurs when the refracted light (focal point) is focused in front of the retina.

Answers:

True

False

Question 8

The malleus, incus, and stapes can be found in which part of the ear?

Answers:

Inner ear

Middle ear

Outer ear

External ear

Question 9

Which statement is true regarding balance and equilibrium within the inner ear?

Answers:

The spiral organ plays a vital role in balance

Unlike hearing, equilibrium is not innervated with a cranial nerve

The saccule and utricle depend on otoliths to assist in stimulating their sensory hair cells

The inner ear is innervated by cranial nerve (CN) VII, the facial nerve.

Question 10

Which choice is true regarding the eye?

Answers:

A hyperopic eye occurs when the refracted light is focused behind the retina

The sclera is part of the internal eye and changes shape to focus light

A function of the ciliary body is to absorb light and prevent it from scattering around the eye

The lens shape and thickness cannot be adjusted

Question 11

Which statement is true regarding the special senses?

Answers:

If the olfactory bulb is damaged, an individual’s sense of equilibrium will be partially lost

If the light entering the eye is refracted on two different areas of the retina, double vision will occur

If an individual is missing a particular category of rod cells, he or she will be colorblind

Conductive hearing loss can result from damaged or dead hair cells (stereocilia)

Question 12

What condition causes the lens to become defective due to clouding and leads to distorted vision?

Selected Answer:

Cataracts

Answers:

Glaucoma

Cataracts

Astigmatism

Conjunctivitis

Question 13

Which of the following structures is in direct contact with the tympanic membrane?

Answers:

Malleus

Incus

Stapes

Utricle

Question 14

Which special sense does not depend on an organ with sensory hairs to assist in their function?

Answers:

Hearing

Sight

Smell

Taste

Question 15

When the sound waves are blocked from reaching the inner ear, resulting in impaired hearing, this is referred to as:

Answers:

Sensorineural hearing loss

Conductive hearing loss

Tinnitus

Vertigo
