Nerve Receptors - Name the nerve receptor according to its description:

Question 1

Also known as a tactile corpuscle

Answer 1

Meissner’s corpuscle

Question 2

A unique type of epithelial cell

Answer 2

Merkel disc

Question 3

Also known as a lamellated

corpuscle

Answer 3

Pacinian corpuscle

Question 4

Found in mucous membranes

Answer 4

Krause end bulb

Question 5

Found in some joints

Answer 5

Ruffini corpuscle

Question 6

Have a spiraled dendrite

Answer 6

Meissner’s corpuscle

Question 7

Provide sensory information

for most organs

Answer 7

Krause end bulb

Question 8

Which three nerve receptors provide discriminative touch information?

Answer 8

Merkel disc, Meissner’s corpuscle, Krause end bulb

Question 9

How is crude touch information different from discriminative touch information?

Answer 9

Crude touch does not give very detailed information about the object touching the skin
compared to discriminative touch. “Crude” means nonspecific, less descriptive
information. Discriminative touch information informs you of the exact location, texture,
size, and movement of the object on the skin.

Question 10

Which two nerve receptors respond to deep pressure and high frequency
vibrations?

Answer 10

Pacinian and Ruffini corpuscles

Question 11

How do phasic receptors respond to something pressing upon the skin?

Answer 11

Phasic receptors initially respond to an object on the skin but stop responding if the
object continues to press on the skin. This means they allow you to be temporarily of
an object on the skin. I.e., they allow you to ignore a long-term stimulus.

Question 12

Which two nerve receptors did we talk about as being phasic?

Answer 12

Pacinian and Meissner’s corpuscles

Question 13

How do tonic receptors respond to something pressing upon the skin?

Answer 13

Tonic receptors always respond to an object on the skin as long as it continues to
press on the skin. They allow you to be constantly aware of long-term stimulus on the
skin.

Question 14

Which two nerve receptors are examples of tonic receptors?

Answer 14

Merkel disc, Ruffini corpuscle

Question 15

Which two nerve receptors provide crude touch information?

Answer 15

Ruffini and Pacinian corpuscles

Question 16

In what major way are the Merkel Disc and Meissner’s corpuscle alike?
In what two major ways are they different?

Answer 16

Both the Merkel disc and Meissner’s corpuscle respond to light pressure and give
discriminative touch information.
However, the Merkel disc is a free nerve ending while the Meissner’s corpuscle is an
encapsulated nerve ending. The Merkel disc is a tonic receptor while the Meissner’s
corpuscle is a phasic receptor.
