Autonomic Nervous System drugs Flashcards
(20 cards)
What is Autonomic Nervous System?
Involuntary physiological activities including heart rate, blood pressure, breathing, digestion, and sexual arousal are regulated by the autonomic nervous system, a part of the peripheral nervous system.
What are the 2 key components in the ANS?
Sympathetic/Adrenergic and Parasympathetic/Cholinergic
What is Somatic Nervous System
The somatic nervous system, also known as the voluntary nervous system, is the area of the peripheral nervous system responsible for the voluntary regulation of skeletal muscle movement.
What are the 2 types of neurons?
Afferent and Efferent
What is the difference between Afferent and Efferent?
Afferent is directly send impulses to the central nervous system while the efferent is receiving impulses communicates to cells of effector organs through the spinal cord.
What is neurotransmitters?
Your body depends on neurotransmitters, which are chemical messengers. They are responsible for transporting chemical signals, or “messages,” from one neuron (nerve cell) to the subsequent target cell.
What is Synaptic Transmission?
The biological mechanism through which a neuron interacts with a target cell across a synapse is known as synaptic transmission.
What is Sympathetic Nervous System?
SNS impulses are reactions to a very precise set of stimuli necessitating activation of the “fight or flight” response. The Terminal Neurotransmitter is Norepinephrine also the Receptor organ cells are Alpha and Beta.
What is Parasympathetic Nervous System?
The PNS is made up of preganglionic and postganglionic nerves, just as the SNS. The Terminal Neurotransmitter is Nicotinic and Muscarinic.
What are the difference between Sympa and Parasympa?
SYMPA – PARASYMPA
Dilates Pupils – Constrict pupils
Dilates Brochioles – Constrict Bronchioles,Increase Secretions
Increase Heart Rate – Decrease Heart Rate
Constricts Blood Vessels – Dilates Blood Vessels
Relaxes smooth muscles of the GI – Increases peristalsis
What is the muscle contract when pupil response?
When pupil Constricts, the pupil response is bright light, and it is a Circular Muscle Contract. While when pupil Dilates, the pupil response is dim light, and it is a Radial Muscle Contract.
What is the Receptor Theory?
Drugs work by attaching to receptors to either start or stop a reaction, depending on the situation. It is comparable to how well a lock fits when the proper key is used.
What is Agonist?
Medications that cause a reaction.
What is Antagonist?
Medications that prevent reactions.
What is Pharmacologic Effect?
When autonomic medications are used, the intention is to address target organ dysfunction rather than an autonomic condition.
What is Symphathomimetics?
It is a medications that replicate the actions of endogenous agonists of the sympathetic nervous system. It is also known as adrenergic drugs.
What are the category based on chemical structures?
Catecholamines and Noncatecholamines
What are the side effects of Adrenergic Agonist?
When the patient has Tissue necrosis, we are going to check IV sites frequently. Also if the patient Nausea and Vomiting, offer food.
What is Adrenergic Blockers?
It is a drugs that lower blood pressure. The way that beta blockers function is by obstructing the actions of the hormone epinephrine, also referred to as adrenaline. Beta blockers reduce blood pressure by causing the heart to beat more gradually and gently.
What is Orthostatic Hypotension?
A type of low blood pressure known as orthostatic hypotension occurs when someone stands up after sitting or lying down. Orthostatic hypotension can make you feel woozy, lightheaded, and even faint.
