The most common cause of the cholinergic crisis is from medication or accidental exposure to insecticides such as Malathion or herbicides.
Other sources include nerve gas such as sarin gas and VX gas. Use of these weapons is against the rules of warfare set by the Geneva Convention established in 1925. Recently they have been used as weapons of terrorism.
A cholinergic crisis describes the condition of excess acetylcholine at neuromuscular junctions and the synaptic gap in the central and peripheral nervous system.
Acetylcholine acts as a neurotransmitter for muscle fibers, in the peripheral nervous system, and extensively in the brain. The enzyme acetylcholinesterase rapidly breaks down the neurotransmitter once it is released.
Not enough acetylcholinesterase leads to a buildup of acetylcholine and an increase in the level and duration of neurotransmitter signal. Symptoms of the cholinergic crisis include excess salivation (drooling), lacrimation (many tears), emesis (vomiting), and diarrhea.
Striated and smooth muscles eventually stop responding due to the accumulation of acetylcholine. The result is paralysis and respiratory failure.

What agent blocks enzymes resulting in a cholinergic crisis?
There are many. The enzymes that can be affected are choline acetyltransferase (for making acetylcholine), and acetylcholinesterase (for breaking down acetylcholine). The most commonly used enzyme inhibitors affecting the cholinergic system are the acetylcholinesterase inhibitors, such as physostigmine, or neostigmine, etc.
What do Cholinergic fibers secrete?
Acetylcholine (Ach), which causes sweat production
When cholinergic receptors are stimulated they?
sodium ions enter the postsynaptic neuron.
What secretes norepinephrine adrenergic fibers?
sympathetic division. Parasympathetic division fibers called cholinergic fibers release acetylcholine.
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 is Sar of cholinergic drugs?
what is sar of cholinergic drug
What is the cholinergic response?
cholinergic is receptor that secrete the acitylcholine
What is cholinergic and anti cholinergic drugs?
Cholinergic drugs are used for urinary retention, myasthenia gravis, glaucoma. Cholinergic drugs act like the neurotransmitter ACh (acetylcholine). Anti Cholinergic (also called Cholinergic blocking) drugs block the action of the ACh. Anti Cholinergic drugs are used foe pylorospasm & peptic ulcers, bladder overactivity, parkinson's disease
What do cholinergic neurons secrete?
Cholinergic neurons secrete acetylcholine.
What are the consequences of the crisis?
it causes a famine
What will be the effect of cholinergic agonist on the pyloric sphincter?
The pyloric sphincter is mediated by excitatory cholinergic vagal fibers, so a cholinergic agonist would constrict the sphincter.
