Nervous System Flashcards
What are the two receptors of Sympathetic Nervous System?
- Alpha receptors
- Beta receptors
What are the two receptors of the Parasympathetic Nervous System?
- Muscarinic receptors
- Nicotinic receptors
What are the four types of Nervous System drugs?
- Adrenergic Agonist
- Adrenergic Antagonists
- Cholinergic Drugs
- Anticholinergic Agent
This is known as the other name for Adrenergic Agonist. This mimics or modifies the actions of SNS.
Sympathomimetic
This is the other name for Adrenergic Antagonists. This opposes the actions of the SNS and blocks adrenergic receptors. Antiadrenergic Drugs.
Sympatholytic
This is the other name for Cholinergic Agents. Its actions resemble acetylcholine.
Parasympathomimetic
This is the other name for Anticholinergic Agent. It inhibits actions of the acetylcholine.
Parasympatholytic
What hormones are associated with SNS?
Adrenaline (Epinephrine, Norepinephrine)
What hormones are associated with PNS?
Acetylcholine
What muscles do acetylcholine affect?
skeletal mucles and neuromuscles
What does Adrenaline affect?
Lungs, heart, and smooth muscles
What affects the following?
- a1
- a2
- b1
- b2
- smooth muscle glands
- smooth muscle glands
- heart
- lungs
What are the usual indications of Cholinergic Agonists?
Myasthenia Gravis
Alzheimer’s Disease
Give atleast five (5) autonomic responses of the sympathetic nervous system.
- Dilates pupil
- Relaxes bronchi, increases heart rate
- Inhibits salivation
- Stimulates epinephrine and norepinephrine release
- Orgasm, ejaculation, contracts rectum
Give atleast five (5) autonomic responses of the parasympathetic nervous system.
- Constricts pupil
- Constricts bronchi, decreases heart rate
- Stimulate salivation
- Inhibition of adrenaline release
- Stimulates gallbladder
Which one is an autonomic response of the PNS?
A. Constrict pupil
B. Dilate pupil
C. Increases heart rate, relaxes bronchi
D. Stimulates epinephrine and norepinephrine release
A. Constrict pupil
Which one is an autonomic response of the SNS?
A, Stimulates gallbladder
B. Stimulates glucose release by liver
C. Constricts bronchi, decreases heart rate
D. Relaxes rectum
B. Stimulates glucose release by liver
Which one is an autonomic response of the PNS?
A. Relaxes rectum
B. Contracts rectum
C. Relaxes bladder
D. Orgasm, ejaculation
A. Relaxes rectum
Give 5 alpha and beta adrenergic agonists.
- Dobutamine
- Dopamine
- Norepineprhine
- Ephedrine
- Epinephrine
Give 5 beta specific adrenergic agonist
- Formoterol
- Albuterol
- Terbutaline
- Arformoterol
- Levalbuterol
Usual indications for beta specific adrenergic agonists
asthma, copd,
Usual indications for alpha and beta specific adrenergic agonists
shock, cardiac arrest, hypotension, bronchospasm
This is a chronic muscular disease caused by a defect in neuromuscular transmission, autoimmune disease in which patients make antibodies to their ACh receptors
Myasthenia Gravis
It is a progressive disorder involving neural degeneration in the cortex.
Alzheimer’s disease
