What does sympathomiminic mean?
An agent that mimics the effects of the sympathetic nervous system.Example: Epinephrine and norepinephrine are sympathomimetic hormones because they produce effects that mimic those brought about by the sympathetic nervous system.
Does the effect of epinephrine mimic the effect of the sympathetic nervous system or the parasympathetic nervous system?
The effect of epinephrine mimics the effect of the sympathetic nervous system. Epinephrine is also known as adrenaline, and it activates the "fight or flight" responses in the body, such as increasing heart rate, dilating airways, and increasing blood flow to muscles.
What type of drug are amphetamines?
Amphetamines are stimulants of the central nervous system and sympathetic division of the peripheral nervous system.
What is a sympatholytic drug?
a drug that inhibits the action of the sympathetic sysytem
What component of the nervous system is associated with the fight or flight?
sympathetic nervous system.
How would a drug that stimulates acetylcholine receptors affect the sympathetic nervous system?
Preganglionic fibers for the SNS release ACh; so a drug that stimulates ACh receptors would stimulate the postganglionic fibers of sypathetic nerves, resulting in increased sympathetic activity
What drug mimics serotonin so that there is an abundance of it in the synapse?
Ecstasy
Which division of the autonomic nervous system does epinephrine imitate?
The sympathetic (fight or flight) system.
What nervous system gets your body ready for action in an emergency by increasing adrenalin and slowing down digestion.?
sympathetic division of the autonomic nervous system
What is unopposed sympathetic activity?
Unopposed sympathetic activity is when the sympathetic nervous system is overly stimulated without a counterbalancing effect from the parasympathetic nervous system. It can lead to symptoms such as rapid heart rate, high blood pressure, sweating, and feelings of anxiety or agitation. This imbalance can occur in conditions like panic attacks or certain drug overdoses.
