Homework 18 Chapter
Question 1A person who is farsighted cannot see close objects because
the lens is too small.
the eyeball is too short.
of a lack of rod receptors.
the eyeball is too long.
the optic nerve is damaged.
Question 2Taste buds and olfactory cells are considered
mechanoreceptors.
radioreceptors.
chemoreceptors.
general receptors.
proprioceptors.
Question 3The order in which light reaches the lens of a human eye is
cornea → vitreous humor → pupil → lens.
pupil → cornea → aqueous humor → lens.
cornea → pupil → aqueous humor → lens.
cornea → aqueous humor → pupil → lens.
lens → aqueous humor → pupil → cornea.
Question 4The structure that regulates the size of the opening for light in the eye is the
retina.
ciliary muscle.
lens.
pupil.
iris.
Question 5Vertigo would most likely result from
increased vibrations in the basilar membrane.
continuous fluid movement in the semicircular canals.
lack of red or green cones.
bipolar cells stimulating the retina.
continuous stimulation of the tympanic membrane.

temporal lobe
pons
medulla
brain stem
limbic system
Question 7When a baseball player is hit in the back by a ball, what is detected by the pain receptors?
The body’s position during the time of the injury.
Chemicals that are released by the damaged cells.
The pressure produced by the trauma.
The temperature of the day.
None of the answer choices would be detected by the pain receptors.
Question 8When a stimulus is continuous but we no longer respond to it, the process is called
sensory adaptation.
integration.
proprioception.
countersensation.
somatic sensing.
Question 9When an internal pain is felt in a surface region of the skin, it is called
countersensation.
referred pain.
somatic sensing.
proprioception.
sensory adaptation.
