Question 1

In the figure below, which letter represents the celiac ganglion (one of the four major prevertebral ganglia)? 
A) A
B) B
C) C
D) D

Accepted Answer

The answer of In the figure below, which letter represents...

Question 2

The _____ division of the autonomic nervous system is mostly responsible for regulating restorative, energy-conserving body activities.
A) sympathetic
B) parasympathetic
C) somatic

Accepted Answer

The parasympathetic division of the autonomic nervous system is known as the "rest and digest" division and is responsible for regulating restorative, energy-conserving body activities such as digestion and lowering heart rate. The sympathetic division is responsible for the "fight or flight" response, which is activated in times of stress or danger. The somatic division is responsible for voluntary control of skeletal muscles.

Question 3

Autonomic neurons that release the neurotransmitter norepinephrine are called _____ neurons.
A) cholinergic
B) dopaminergic
C) seratonergic
D) adrenergic

Accepted Answer

Autonomic neurons that release norepinephrine are called adrenergic neurons. Cholinergic neurons release acetylcholine, dopaminergic neurons release dopamine, and serotonergic neurons release serotonin.

Question 4

Which division of the autonomic nervous system is the specialized network of nerves and ganglia forming a complex, integrated neuronal network within the wall of the gastrointestinal tract, pancreas, and gallbladder ?
A) sympathetic
B) parasympathetic
C) enteric
D) somatic

Accepted Answer

The specialized network of nerves and ganglia forming a complex, integrated neuronal network within the wall of the gastrointestinal tract, pancreas, and gallbladder is called the enteric division of the autonomic nervous system. The sympathetic and parasympathetic divisions are the other two divisions of the autonomic nervous system, but they do not form this specialized network. The somatic nervous system, on the other hand, is responsible for voluntary muscle movement and does not have a direct role in the functioning of the gastrointestinal tract, pancreas, and gallbladder.

Question 5

The cranial nerve that carries most of the parasympathetic outflow is the _____.

Accepted Answer

The answer of The cranial nerve that carries most of...

Question 6

The anterior and medial portions of the hypothalamus control the _____ division of the autonomic nervous system.
A) sympathetic
B) parasympathetic
C) somatic

Accepted Answer

The parasympathetic division of the autonomic nervous system is controlled by the anterior and medial regions of the hypothalamus. The sympathetic division is not controlled by these regions. The somatic division is not part of the autonomic nervous system.

Question 7

The posterior and lateral portions of the hypothalamus control the _____ division of the autonomic nervous system.
A) sympathetic
B) parasympathetic
C) somatic

Accepted Answer

The sympathetic division of the autonomic nervous system is responsible for the "fight or flight" response, which includes increasing heart rate, dilating pupils, and decreasing digestive activity. The posterior and lateral portions of the hypothalamus are specifically involved in the control of this division.

Question 8

Autonomic innervation (stimulation) from the _____ division results in vasoconstriction of blood vessels in the dermis of the skin.
A) sympathetic
B) parasympathetic
C) somatic
D) None of these choices

Accepted Answer

Vasoconstriction in the dermis of the skin is a response to sympathetic innervation/stimulation. Parasympathetic innervation typically results in vasodilation, and somatic innervation is involved in voluntary movement and control of skeletal muscles, not autonomic functions like vasoconstriction.

Question 9

The _____ is the major control and integration center of the autonomic nervous system.
A) thalamus
B) cerebrum
C) hypothalamus
D) cerebellum

Accepted Answer

The hypothalamus is known as the major control and integration center of the autonomic nervous system. It is responsible for regulating many bodily functions such as temperature, hunger, thirst, and sleep.

Question 10

This leader line points to the right sympathetic trunk ganglion which receives preganglionic axons from thoracic and lumbar spinal cord segments. 
A) A
B) B
C) C
D) D

Accepted Answer

The answer of This leader line points to the right...

Question 11

The lateral gray horns of the thoracic region contain cell bodies of _____ (sympathetic or parasympathetic) preganglionic neurons.

Accepted Answer

The answer of The lateral gray horns of the thoracic...

Question 12

Splanchnic nerves carry sympathetic axons (fibers) from a/an _____ ganglion to a/an _____ ganglion.

Accepted Answer

The answer of Splanchnic nerves carry sympathetic axons (fibers) from...

Question 13

This leader line points to the greater splanchnic nerve which synapses with postganglionic cell bodies in the celiac ganglion. 
A) A
B) B
C) C
D) D

Accepted Answer

The leader line points towards the region where the greater splanchnic nerve synapses with the postganglionic cell bodies in the celiac ganglion, which is located in close proximity to option B.

Question 14

The facial (VII) cranial nerves carry parasympathetic preganglionic axons (fibers) to two pairs of terminal ganglia: the _____ and the _____ ganglia.

Accepted Answer

The answer of The facial (VII) cranial nerves carry parasympathetic...

Question 15

This leader line points to right vagus (X) nerve which supplies parasympathetic fibers to most of the trunk viscera. 
A) A
B) B
C) C
D) D

Accepted Answer

The answer of This leader line points to right vagus...
