A)carotid bodies.
B)aortic bodies.
C)in the skin.
D)the organs of taste.
E)the organs of smell.

Accepted Answer

Chemoreceptors are not located in the skin. They are sensory receptors primarily found in the carotid bodies and the aortic bodies, which are clusters of cells located near the carotid artery and the aorta respectively. Chemoreceptors can also be found in the organs of taste and smell.

A)chemoreceptor.
B)mechanoreceptor.
C)thermoreceptor.
D)nociceptor.
E)free receptor.

Accepted Answer

Nociceptors are sensory receptors that respond to noxious or potentially damaging stimuli, such as extreme heat or cold, intense pressure, or tissue damage. They are typically characterized peripherally as free nerve endings and centrally use glutamate and/or substance P as neurotransmitters.

Question 4

A very large,fast-adapting tactile receptor that is composed of a single dendrite enclosed by concentric layers of collagen is a
A)Ruffini corpuscle.
B)lamellated corpuscle.
C)tactile (Meissner)corpuscle.
D)tactile (Merkel)disc.
E)root hair plexus.

Accepted Answer

The description matches that of a lamellated corpuscle, which is a fast-adapting tactile receptor composed of a single dendrite enclosed by concentric layers of collagen. Ruffini corpuscles have elongated and branched dendrites, tactile (Meissner) corpuscles have a stack of flattened cells around the dendrite, tactile (Merkel) discs have flattened cells around the dendrite, and root hair plexus are a network of nerves around hair follicles.

Question 5

Pain is to ________ as cold is to ________.
A)nociceptors; thermoreceptors
B)baroreceptors; chemoreceptors
C)baroreceptors; nociceptors
D)chemoreceptors; nociceptors
E)baroreceptors; thermoreceptors

Accepted Answer

Pain is detected by nociceptors, which are sensory neurons that respond to harmful stimuli, while cold is detected by thermoreceptors, which respond to changes in temperature. Therefore, the most appropriate pair of receptor types to complete the analogy is nociceptors and thermoreceptors, which are represented by choice A.

Question 6

Which of the following is not a property of thermoreceptors?
A)sensation conducted in same pathway as pain
B)tonic response to temperature change
C)found in skeletal muscle,hypothalamus,and skin
D)project to reticular formation
E)cold receptors outnumber warm receptors

Accepted Answer

Thermoreceptors typically have a phasic response to temperature change, meaning they adapt quickly and are more sensitive to changes in temperature rather than maintaining a constant response.

Question 7

Receptors that monitor the position of joints belong to the category called
A)nociceptors.
B)chemoreceptors.
C)baroreceptors.
D)proprioceptors.
E)thermoreceptors.

Accepted Answer

Receptors that monitor the position of joints belong to the category called proprioceptors. Nociceptors are pain receptors, chemoreceptors respond to chemical stimuli, baroreceptors monitor blood pressure, and thermoreceptors respond to temperature changes.

Question 8

Tactile receptors composed of capsules that surround a core of collagen fibers intertwined with dendrites are called
A)Ruffini corpuscles.
B)lamellated corpuscles.
C)tactile (Meissner)corpuscles.
D)tactile discs.
E)root hair plexuses.

Accepted Answer

The description matches that of Ruffini corpuscles, which are located in the dermis of the skin and are responsible for detecting sustained pressure and stretch.

Question 9

________ are receptors in the aorta that monitor the blood pressure.
A)Chemoreceptors
B)Nociceptors
C)Baroreceptors
D)Proprioceptors
E)Hair cells

Accepted Answer

Baroreceptors are specialized cells that detect changes in pressure in blood vessels, including the aorta. They help regulate blood pressure by sending signals to the brain that can cause adjustments in heart rate and blood vessel diameter. Chemoreceptors detect changes in oxygen and carbon dioxide levels, nociceptors detect pain, proprioceptors detect body position, and hair cells are sensory receptors in the ear.

Question 10

Tactile discs are to ________ as tactile corpuscles are to ________.
A)Wilms; Meissner
B)Merkel; Meissner
C)Meissner; Merkel
D)Pacinian; Merkel
E)pain; pressure

Accepted Answer

The answer of Tactile discs are to ________ as tactile...

Question 11

A tactile receptor composed of highly coiled dendrites that are surrounded by modified Schwann cells and a fibrous capsule is a
A)lamellated corpuscle.
B)Ruffini corpuscle.
C)tactile (Meissner)corpuscle.
D)tactile (Merkel)disc.
E)root hair plexus.

Accepted Answer

The answer of A tactile receptor composed of highly coiled...

Question 12

Sensations of burning or aching pain
A)are carried by type A fibers.
B)reach the CNS quickly.
C)cause a generalized activation of the reticular formation and the thalamus.
D)are well localized.
E)are fast adapting.

Accepted Answer

Sensations of burning or aching pain cause a generalized activation of the reticular formation and the thalamus, leading to the perception of pain. This is regardless of the type of fibers carrying the information, their speed, or their localization ability.

Question 13

Bladder fullness is to ________ as blood pH is to ________.
A)nociceptors; thermoreceptors
B)baroreceptors; chemoreceptors
C)baroreceptors; nociceptors
D)chemoreceptors; nociceptors
E)baroreceptors; thermoreceptors

Accepted Answer

Bladder fullness triggers the activity of baroreceptors, which detect changes in pressure, while blood pH is monitored by chemoreceptors, which are specialized in detecting changes in chemical composition.

Question 14

If a friend is talking about someone she knows who lost his special senses,you would correct her when you hear her mention ________,because it is not a special sense.
A)smell
B)sight
C)balance
D)cold
E)hearing

Accepted Answer

Cold is not a special sense. The special senses are sight, hearing, taste, smell, and balance.

Question 15

Mechanoreceptors that respond to changes in blood pressure are called
A)nociceptors.
B)baroreceptors.
C)chemoreceptors.
D)proprioceptors.
E)thermoreceptors.

Accepted Answer

Baroreceptors specifically detect changes in blood pressure and send signals to the brain to regulate it. Nociceptors detect pain, chemoreceptors detect chemical changes, proprioceptors detect body position and movement, and thermoreceptors detect temperature changes.

Question 16

A)lamellated corpuscle.
B)tactile (Meissner)corpuscle.
C)Ruffini corpuscle.
D)tactile (Merkel)disc.

Accepted Answer

A tactile (Merkel) disc is a highly sensitive tactile receptor composed of dendritic processes of a single myelinated fiber that makes contact with specialized cells of the stratum germinativum.

Question 17

Tickle is to ________ as itch is to ________.
A)pressure; heat
B)baroreceptors; chemoreceptors
C)touch; pain
D)stretch; temperature
E)thermoreceptors; nociceptors

Accepted Answer

Tickle is related to touch as it is a sensation caused by light pressure or movement on the skin, while itch is related to pain as it is an irritating sensation that often leads to the desire to scratch, which can be painful.

Question 18

Which of the following kinds of information do fine-touch and light-pressure mechanoreceptors provide?
A)location of the stimulus
B)shape of the stimulus
C)texture of the stimulus
D)movement of the stimulus
E)All of the answers are correct.
