Question 1

MATCHING
Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code.
-Predominates in fight-or-flight situations.
A)sympathetic nervous system
B)parasympathetic nervous system
C)both sympathetic and parasympathetic nervous system
D)somatic system

Accepted Answer

The sympathetic nervous system is responsible for the body's response to stress, danger, or excitement. This is known as the "fight or flight" response, which triggers the release of adrenaline and other hormones that prepare the body to react quickly.

Question 2

Parasympathetic preganglionic fibers arise from the ____________________ and ____________________ areas of the CNS.

Accepted Answer

The answer of Parasympathetic preganglionic fibers arise from the ____________________...

Question 3

MATCHING
Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code.
-Postganglionic fiber secretes acetylcholine.
A)sympathetic nervous system
B)parasympathetic nervous system
C)both sympathetic and parasympathetic nervous system
D)somatic system

Accepted Answer

Postganglionic fibers of the parasympathetic nervous system secrete acetylcholine, while the postganglionic fibers of the sympathetic nervous system secrete norepinephrine. Therefore, the best choice is B, which corresponds to the parasympathetic nervous system.

Question 10

MATCHING
Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code.
-Considered adrenergic.
A)sympathetic nervous system
B)parasympathetic nervous system
C)both sympathetic and parasympathetic nervous system
D)somatic system

Accepted Answer

The sympathetic nervous system is considered adrenergic because it releases epinephrine (adrenaline) from the adrenal glands, which increases heart rate, blood pressure, and respiration, and triggers the fight-or-flight response.

Answer: C
 While the sympathetic nervous system is primarily adrenergic, the parasympathetic nervous system also has some adrenergic function, as it can release small amounts of epinephrine in response to stress or exercise. Therefore, both systems can be considered adrenergic to some degree.

Question 15

Centers controlling cardiovascular, respiratory and digestive activity via the autonomic system are located in the _______

Accepted Answer

The answer of Centers controlling cardiovascular, respiratory and digestive activity...

Question 16

MATCHING
Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code.
-Controls voluntary movements.
A)sympathetic nervous system
B)parasympathetic nervous system
C)both sympathetic and parasympathetic nervous system
D)somatic system

Accepted Answer

The somatic system is responsible for controlling voluntary movements, such as those related to skeletal muscles. The autonomic nervous system, on the other hand, controls involuntary functions such as heart rate, digestion, and respiration. The sympathetic and parasympathetic nervous systems are both part of the autonomic nervous system and work together to maintain homeostasis.

Question 17

Parasympathetic fibers arise from cranial nerves ______, _______, _______, and _______. (give numbers of the nerves)	.

Accepted Answer

The answer of Parasympathetic fibers arise from cranial nerves ______,...

Question 18

MATCHING
Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code.
-Preganglionic fiber secretes acetylcholine.
A)sympathetic nervous system
B)parasympathetic nervous system
C)both sympathetic and parasympathetic nervous system
D)somatic system

Accepted Answer

Both the sympathetic and parasympathetic nervous systems have preganglionic fibers that secrete acetylcholine.

Question 19

Binding of ____________________ to nicotinic receptors is always excitatory.

Accepted Answer

The answer of Binding of ____________________ to nicotinic receptors is...

Question 20

Indicate the proper sequence of events at the neuromuscular junction by filling in the blank with the appropriate number from 2 through 7. Numbers 1 and 8 are already identified. _____ ACh is released from the axon terminal by exocytosis. _____ An EPP takes place, primarily as a result of Na⁺ influx. __8___ Acetylcholinesterase inactivates ACh, terminating activity at the neuromuscular junction. ___1__ An action potential is propagated to an axon terminal of a motor neuron. _____ Channels that permit passage of Na⁺ and K⁺ are opened in the motor end plate. _____ Ca²⁺ channels are opened in the axon terminal. _____ Local current flow between the motor end plate and adjacent muscle-cell membrane initiates an action potential that spreads throughout the muscle fiber. _____ ACh binds with receptor sites on the motor end plate.

Accepted Answer

The answer of Indicate the proper sequence of events at...
