What will be the effect of cholinergic agonist on the pyloric sphincter?
Wiki User
∙ 11y ago
The pyloric sphincter is mediated by excitatory cholinergic vagal fibers, so a cholinergic agonist would constrict the sphincter.

A cholinergic agonist will cause the pyloric sphincter to relax, leading to increased gastric emptying. This is because cholinergic stimulation promotes smooth muscle relaxation in the gastrointestinal tract, allowing food to pass through the pyloric sphincter more easily.

Is decrease GI motility and secretion has a cholinergic effect?
No, decreased gastrointestinal (GI) motility and secretion are not typically associated with a cholinergic effect. Cholinergic stimulation usually leads to increased GI motility and secretion. Other factors like sympathetic activity or certain drugs may be responsible for decreased GI motility and secretion.
The effect of a drug that is an agonist is to do what?
An agonist drug binds to and activates a receptor in the body, producing a response similar to that of the endogenous ligand. This leads to an increase in the activity of the receptor, resulting in a physiological response.
Will vicodin cause spasms in the sphincter of the oddi?
Vicodin, which contains hydrocodone and acetaminophen, can cause sphincter of Oddi spasm due to the opioid component's effect on smooth muscle contraction. It is important to consult a healthcare provider if you experience symptoms of sphincter of Oddi dysfunction, as it can lead to serious complications like pancreatitis.
13 What is a possible side effect of weakening of the cardiac sphincter?
A possible side effect of weakening of the cardiac sphincter is gastroesophageal reflux disease (GERD). This can lead to symptoms like heartburn, chest pain, and regurgitation of stomach acid into the esophagus. Over time, chronic GERD can damage the esophagus and increase the risk of developing complications like esophagitis or Barrett's esophagus.
How does parasympathetic stimutaion effect the bowel?
The parasympathetic effect on urination will be that of bladder stimulation and resultant voiding of urine. If this stimulation is ecessive it will result in the bladder not being able to hold the urine until voluntary voiding of the urine thus a clinical effect of urinary incontinet results because of lack of control of bladder contraction by the individual.
Is pilocarpine an antagonist or an agonist?
Pilocarpine is actually a Muscarinic cholinergic receptor (mAChR) agonist. It works on the Parasypathetic nervous system; therefore, it makes sense that the agonist working on the PNS would result in decreased heart rate. Atropine, in contrast, is an muscarinic cholinergic receptor antagonist and will lead to increased heart rate due to the lowered effect of the parasympathetic system on the heart.
What precautions need to be taken when using external sphincter electromyography?
Patients who are taking muscle relaxants or drugs that act like or have an effect on the neurotransmitter acetylcholine (cholinergic or anti-cholinergic drugs) should tell the doctor since they will change the test results. The results will.
Which drug may have delayed absorption because of the adverse effect of cholinergic blocking agent?
betablockers
Muscimol is a direct agonist for the gabaa receptor this means that muscimol binds to which spot on the receptor as gaba and what that is has effect as gaba?
Muscimol is a GABA A agonist effet psychotomimetic
The effect of a drug that is an agonist is to?
An agonist binds to a receptor and stimulates it (turns it on). An antagonist binds to a receptor and blocks it from being activated by other molecules (turns it off).
The drug effect in which one drug neutralizes another drug is?
Inverse Agonist.
Is decrease GI motility and secretion has a cholinergic effect?
No, decreased gastrointestinal (GI) motility and secretion are not typically associated with a cholinergic effect. Cholinergic stimulation usually leads to increased GI motility and secretion. Other factors like sympathetic activity or certain drugs may be responsible for decreased GI motility and secretion.
What positive modulation?
Enhancing the action of an agonist without having an individual effect itself.
The effect of a drug that is an agonist is to do what?
An agonist drug binds to and activates a receptor in the body, producing a response similar to that of the endogenous ligand. This leads to an increase in the activity of the receptor, resulting in a physiological response.
What is an opiate agonist?
An opiate agonist gives the user the same feeling as would be experienced by an endorphin, which is a natural compound. The receptors in the brain that feel effects from opiates receive the opiate agonist and feel an opioid effect, even though one isn't really happening.
What effect does Curare have on muscle tissue?
It blocks the nicotinic cholinergic receptors on the muscle that normally bind the acetylcholine released by the motor neuron.
Which atypical antipsychotic will exceptionally increase salivation?
For unknown reasons, Clozapine increases salivation (though it has mild anti-cholinergic effect).
