16 Questions
What are the two main components of the autonomic nervous system?
Central Nervous System (CNS) and Peripheral Nervous System (PNS)
Which part of the nervous system controls and regulates the heart, respiratory system, GI tract, bladder, eyes, and glands?
Autonomic Nervous System (ANS)
What is the main difference between the autonomic nervous system (ANS) and the somatic nervous system?
The ANS controls involuntary functions, while the somatic nervous system controls voluntary functions (skeletal muscle).
What are the two sets of neurons in the autonomic nervous system (ANS)?
Afferent (sensory) and Efferent neurons
What are the two branches of the autonomic nervous system (ANS)?
Sympathetic and parasympathetic nervous system
What is the neurotransmitter associated with the sympathetic nervous system?
Norepinephrine
What is the role of Alpha-2 in the sympathetic nervous system?
Inhibits release of norepinephrine, leading to a decrease in vasoconstriction and blood pressure.
Which neurotransmitter is associated with the parasympathetic nervous system?
Acetylcholine.
What is the function of cholinergic agonists?
They initiate a response in the parasympathetic nervous system.
What is the effect of sympathomimetic drugs on pupil dilation?
They cause pupil dilation.
What is the primary use of Albuterol, an adrenergic drug?
Bronchodilation, for conditions such as bronchospasm, asthma, and bronchitis.
What are the side effects associated with Epinephrine?
Nervousness and agitation.
What is the primary use of Dopamine, an adrenergic agent?
To treat hypotension, shock, increase cardiac output, and improve perfusion to vital organs.
What is the effect of cholinergic antagonists on the parasympathetic nervous system?
They prevent a response in the parasympathetic nervous system.
What is the function of Beta-2 in the sympathetic nervous system?
It causes relaxation of smooth muscle in bronchi, uterus, and peripheral blood vessels.
What is the characteristic response to sympathomimetics/adrenomimetics in terms of blood pressure, heart rate, and bronchodilation?
Increase in blood pressure, heart rate, and bronchodilation.
Test your knowledge of the pharmacology of the autonomic nervous system, including its components such as the central nervous system, peripheral nervous system, and their functions in controlling involuntary bodily functions. This quiz covers the regulation of the heart, respiratory system, GI tract, bladder, eyes, and glands.
