Question

list cholinergic responnses not normally caused when the usual therapeutic doses of muscarinic agonist are administered and explain why these effects do not occur

Answer 1

There are various types of drugs that inhibit, enhance, or mimic the action of the neurotransmitter acetylcholine, the primary transmitter of nerve impulses within the nervous system, that has a nervous system that contracts smooth muscles, dilates blood vessels,

The brain stem complexes are known as cholinergic. The nervous system, uses acetylcholine almost exclusively to send its messages. It is entirely cholinergic. Neuromuscular junctions, neurons of the sympathetic nervous system, the basal forebrain,

If excess medicine is introduced in the body then there are all the chances of having a side effects like excess sweating, loss of bladder control, muscle weakness, nausea, vomiting, stomach pain, irregular heart beats and many others.

The cholinergic muscle stimulants are used to diagnose and treat myasthenia gravis, a disease that causes severe muscle weakness.The responses that a muscarinic agonist would be expected to cause through direct activation of muscarinic cholinergic receptors

One should focus on the main targets of parasympathetic nervous system activity. The eyes, respiratory system, heart and blood vessels, gastrointestinal and urinary tracts, and the secretory activity of exocrine glands for example, lacrimal, mucous, and so on.

The result is constriction increased tone and motility of smooth muscle. In the bladder, muscarinic activation causes contraction of the detrusor muscle and relaxation of the trigone and sphinter; the result is bladder emptying. In vascular smooth muscle, these drugs cause relaxation; the resultant vasodilation can produce hypotension.

Cholinergic drug like other various drugs that inhibit, enhance, or mimic the action of the neurotransmitter acetylcholine., the primary transmitter of nerve impulses within the parasympathetic nervous system. that part of the autonomic nervous system that contracts smooth muscles, dilates blood vessels, increases.

Cholinergic drugs enhance the effects of acetylcholine, increasing the actions of the parasympathetic nervous system. Anticholinergic drugs block effects of acetylcholine, reducing parasympathetic actions and increasing sympathetic ones. Cholinergic drugs are used to treat glaucoma and myasthenia gravis.
