Question 1

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Stimulation of this system often activates many effectors at the same time
A) Sympathetic
B) Parasympathetic

Accepted Answer

The sympathetic division of the autonomic nervous system is known for its "fight or flight" response, which often involves the simultaneous activation of multiple effectors (e.g., increased heart rate, dilation of airways, release of glucose from energy stores) to prepare the body for rapid action.

Question 2

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Increases activity of GI tract
A) Sympathetic
B) Parasympathetic

Accepted Answer

The parasympathetic division of the autonomic nervous system is responsible for "rest and digest" functions, which includes increasing the activity of the gastrointestinal (GI) tract.

Question 3

Match the characteristic with the correct division of the nervous system.
-All axons are myelinated
A) Somatic motor nervous system
B) Autonomic nervous system
C) Both somatic and autonomic nervous systems
D) Neither somatic nor autonomic nervous system

Accepted Answer

The somatic motor nervous system primarily consists of myelinated axons, which facilitate rapid signal transmission to skeletal muscles.

Question 4

Match the characteristic with the correct division of the nervous system.
-Target tissues may be stimulated or inhibited
A) Somatic motor nervous system
B) Autonomic nervous system
C) Both somatic and autonomic nervous systems
D) Neither somatic nor autonomic nervous system

Accepted Answer

The autonomic nervous system controls involuntary actions and regulates the function of internal organs, glands, and blood vessels, allowing for both stimulation and inhibition of target tissues. The somatic nervous system, in contrast, primarily controls voluntary movements and does not typically inhibit target tissues.

Question 5

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Inhibits heart rate but stimulates contraction of urinary bladder
A) Sympathetic
B) Parasympathetic

Accepted Answer

The parasympathetic division of the autonomic nervous system is responsible for "rest and digest" activities, which include slowing down the heart rate and stimulating the contraction of the urinary bladder.

Question 6

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Provides more extensive innervation of digestive tract
A) Sympathetic
B) Parasympathetic

Accepted Answer

The parasympathetic division of the autonomic nervous system is primarily responsible for "rest and digest" functions, which includes more extensive innervation of the digestive tract to promote digestion and absorption of food.

Question 7

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Can produce widespread sweating
A) Sympathetic
B) Parasympathetic

Accepted Answer

The sympathetic division of the autonomic nervous system is responsible for the "fight or flight" response, which includes the ability to produce widespread sweating. This is part of the body's mechanism to cool down during stress or high activity. The parasympathetic division, on the other hand, is more involved in "rest and digest" functions and does not typically induce sweating.

Question 8

Consider the two statements and use the following key to choose your answer.
-(1) The number of sympathetic impulses produced when a person is angry
(2) The number of sympathetic impulses produced when a person is relaxed
A)First item is greater than the second item.
B)First item is less than the second item.
C)Both items are equal or nearly equal.

Accepted Answer

When a person is angry, the sympathetic nervous system is activated more intensely, leading to an increase in sympathetic impulses compared to when a person is relaxed. This is part of the "fight or flight" response, which prepares the body to either confront or flee from perceived threats.

Question 9

Match the characteristic with the correct division of the nervous system.
-Controls conscious movement
A) Somatic motor nervous system
B) Autonomic nervous system
C) Both somatic and autonomic nervous systems
D) Neither somatic nor autonomic nervous system

Accepted Answer

The somatic motor nervous system is responsible for controlling voluntary movements, such as those of the muscles involved in walking, grabbing, or talking. This division of the nervous system specifically manages conscious movement.

Question 10

Match the characteristic with the correct division of the nervous system.
-Receptor molecules may be muscarinic or adrenergic
A) Somatic motor nervous system
B) Autonomic nervous system
C) Both somatic and autonomic nervous systems
D) Neither somatic nor autonomic nervous system

Accepted Answer

Receptor molecules being muscarinic or adrenergic is a characteristic of the autonomic nervous system, which regulates involuntary body functions such as blood flow and digestion. These receptors are not found in the somatic motor nervous system, which controls voluntary muscle movements.

Question 11

Match the characteristic with the correct division of the nervous system.
-Acetylcholine is a neurotransmitter substance
A) Somatic motor nervous system
B) Autonomic nervous system
C) Both somatic and autonomic nervous systems
D) Neither somatic nor autonomic nervous system

Accepted Answer

Acetylcholine is a neurotransmitter that is used in both the somatic motor nervous system, where it stimulates muscle contractions, and in the autonomic nervous system, where it is involved in various functions including stimulating the parasympathetic nervous system.

Question 12

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Effects more localized
A) Sympathetic
B) Parasympathetic

Accepted Answer

The parasympathetic division of the autonomic nervous system is known for having more localized effects compared to the sympathetic division, which tends to have more widespread effects on the body.

Question 13

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Release of epinephrine and norepinephrine
A) Sympathetic
B) Parasympathetic

Accepted Answer

The release of epinephrine and norepinephrine is associated with the sympathetic division of the autonomic nervous system, which is responsible for the body's "fight or flight" response.

Question 14

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Effects are more general
A) Sympathetic
B) Parasympathetic

Accepted Answer

The sympathetic division of the autonomic nervous system tends to have more general effects because it prepares the body for "fight or flight" responses, often affecting multiple organs and systems simultaneously.

Question 15

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Has greater influence during physical activity
A) Sympathetic
B) Parasympathetic

Accepted Answer

The sympathetic division of the autonomic nervous system is more active during physical activity, as it prepares the body for "fight or flight" responses, increasing heart rate, blood pressure, and energy availability.

Question 16

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Thoracolumbar division
A) Sympathetic
B) Parasympathetic

Accepted Answer

The sympathetic division of the autonomic nervous system is also known as the thoracolumbar division because its neurons originate in the thoracic and lumbar regions of the spinal cord.

Question 17

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Craniosacral division
A) Sympathetic
B) Parasympathetic

Accepted Answer

The parasympathetic division of the autonomic nervous system is also known as the craniosacral division because its preganglionic neurons originate in the brainstem (cranial) and the sacral spinal cord.

Question 18

Match the phrase to either the sympathetic or parasympathetic division of the autonomic nervous system.
-Effects are short-lived
A) Sympathetic
B) Parasympathetic

Accepted Answer

The parasympathetic division typically has short-lived effects because it uses acetylcholine, which is quickly broken down by enzymes.

Question 19

Consider the two statements and use the following key to choose your answer.
-(1) The number of sympathetic neurons that innervate sweat glands
(2) The number of parasympathetic neurons that innervate sweat glands
A)First item is greater than the second item.
B)First item is less than the second item.
C)Both items are equal or nearly equal.

Accepted Answer

Sweat glands are primarily innervated by sympathetic neurons, not parasympathetic neurons. This means the number of sympathetic neurons innervating sweat glands is greater than the number of parasympathetic neurons, as the latter is essentially nonexistent in this context.

Question 20

Match the characteristic with the correct division of the nervous system.
-Neuron cell bodies are in the cerebral cortex
A) Somatic motor nervous system
B) Autonomic nervous system
C) Both somatic and autonomic nervous systems
D) Neither somatic nor autonomic nervous system

Accepted Answer

The somatic motor nervous system involves neuron cell bodies located in the cerebral cortex, which is responsible for voluntary motor control.
