Question
Chapter 50, Problem 7TYK
Summary Introduction
Introduction: The auditory system and vestibular system of the ear contain some sensory receptors, which help the animals to detect the movement that occurs in their environment. These receptors are known as hair cells.

What function do the malleus, incus, and stapes bones in the inner ear play in processing sounds?
A.
The bones transform pressure waves into nerve impulses that the brain recognizes as sound.
B.
The bones equalize pressure between the middle ear and the atmosphere.
C.
The bones transmit vibrations to the oval window setting the fluid in the cochlea in motion.
D.
The bones depolarize or hyperpolarize hair cells depending on the direction they vibrate.
Which statement regarding rods and cones is most accurate?
a.) Rods and cones carry signals to the brain so an image can be formed.
b.) Rods and cones refract light to focus it on the retina.
c.) Rods and cones are photoreceptors, which detect light.
d.) Rods and cones monitor the amount of light entering the eye and adjust the size of the pupil.
When you begin to move up or down in an elevator, you can still sense that you are moving even though there are no visual cues. Which sensory organ would be most responsible for detecting this?
a.
Merkel cells
b.
Pacinian corpuscles
c.
Otolith organs
d.
Semicircular canals
