C)receptors that respond to several types of stimuli.
D)receptors only found in humans.
E)unencapsulated receptors.

Answer 1

B

Question 2

In this experiment, which part of the body showed the smallest 2-point threshold?

A)Palm of the hand
B)The forearm
C)Fingertip
D)The leg
E)The back of the neck

Answer 2

C

Question 3

An environmental temperature of 85°F would stimulate a ________, and a temperature of 180°F would stimulate a ________.

A)nociceptor; nociceptor
B)warm receptor; warm receptor
C)thermoreceptor; mechanoreceptor
D)warm receptor; nociceptor
E)mechanoreceptor; thermoreceptor

Answer 3

D

Question 4

All sensory neurons have receptive fields of approximately the same size.

Question 5

Which of the following is NOT a stimulus for various mechanoreceptors?

A)Stretch
B)Cold temperature
C)Deep pressure
D)Vibration
E)Light touch

Question 6

Which of the following receptors do not consist of free nerve endings?

A)Warm receptors
B)Meissner's corpuscles
C)Cold receptors
D)Nociceptors
E)All of these receptors consist of free nerve endings.

Question 7

Tactile and lamellated corpuscles are types of

A)photoreceptors.
B)thermoreceptors.
C)chemoreceptors.
D)nociceptors.
E)mechanoreceptors.

Question 8

Which of the following is NOT true of Meissner's corpuscles?

A)They are also called tactile corpuscles.
B)They are numerous in the hands, feet, joints, and external genital organs.
C)They are most abundant in the hypodermis.
D)They are stimulated by light touch.
E)All of these are true of Meissner's corpuscles.

Question 9

Areas of the body that are capable of precise tactile localization contain more abundant touch receptors than areas that are not.

Question 10

The results of the temperature experiment suggest that there is a greater concentration of cold receptors than warm receptors in the skin.

Question 11

The form in which receptors send sensory information to the brain is called perception.

Question 12

For tactile localization, the brain interprets information from touch receptor fields in the

A)primary motor cortex.
B)brainstem.
C)primary somatosensory cortex.
D)diencephalon.
E)cerebellum.

Question 13

Which of the following is NOT true of sensory adaptation?

A)Thermoreceptors commonly undergo sensory adaptation.
B)It involves a fading of sensation upon continuous receptor stimulation.
C)It occurs when a person adjusts to a strong smell in the environment.
D)It commonly occurs in pain receptors.
E)All of these are true of sensory adaptation.

Question 14

Which type of sensory receptors respond to tissue damage, such as a cut, or a temperature or pressure extreme?

A)Mechanoreceptors
B)Thermoreceptors
C)Chemoreceptors
D)Tactile corpuscles
E)Nociceptors

Question 15

General senses are senses that have sensory receptors distributed widely in the skin, joints, muscles, and organs.
