The autonomic nervous system is responsible for the regulation of:
Involuntary movements
.The two divisions of the autonomic nervous system are:
the sympathetic and parasympathetic nervous systems
Which division of the autonomic nervous system is responsible for the "fight or flight" response?
Sympathetic
The neurotransmitter released by sympathetic postganglionic neurons is:
Norepinephrine
Which of the following is NOT a target organ of the sympathetic division?
Salivary glands
The neurotransmitter released by parasympathetic postganglionic neurons is:
Acetylcholine
The parasympathetic division of the autonomic nervous system is responsible for:
Constriction of pupils
Which of the following is NOT a function of the autonomic nervous system?
Control of skeletal muscles
The autonomic ganglia are located:
Outside the central nervous system
The sympathetic division of the autonomic nervous system is responsible for:
Dilation of bronchioles
The parasympathetic division of the autonomic nervous system is dominant during:
Relaxation and digestion
The sympathetic chain ganglia are located:
Near the spinal cord
Which of the following is NOT a characteristic of the parasympathetic division?
Dilation of blood vessels
The adrenal medulla is an example of a:
Sympathetic ganglion
The autonomic nervous system is primarily regulated by the:
Brainstem
The preganglionic neurons of the sympathetic division originate from the:
Thoracic and lumbar spinal cord
Which of the following is a function of the sympathetic division?
Dilation of the bronchioles
The sympathetic division is activated in response to:
Stress and emergencies
The autonomic nervous system regulates:
Involuntary movements
The parasympathetic division is associated with:
Relaxation and conservation of energy
The neurotransmitter released by sympathetic preganglionic neurons is:
Acetylcholine (ACh)
What chemical does postganglionic neurons of the PNS use as their neurotransmitter?
Acetylcholine (ACh)
