what is acetylcholine?

Acetylcholine is a neurotransmitter used in the peripheral uptight system and the central edgy system. The peripheral tense system is broken into two groups: the autonomic system and the somatic system. Then, the autonomic system is broken down into two more groups: the sympathetic nervous system (associated next to "fight or flight" responses) and the parasympathetic restless system (associated with "rest and digest" responses). Acetylcholine is specifically released in pre- and post-ganglionic parasympathetic neurons and also in preganglionic sympathetic neurons (a ganglion is merely a mass of nerves).have you ever had a really doomed to failure tension headache that last for a very long time??
The chemical compound acetylcholine, normally abbreviated as ACh, was the first neurotransmitter to be identified. It is a chemical transmitter within both the peripheral frightened system (PNS) and central uptight system (CNS) in several organisms including humans. Acetylcholine is an example of a totally untraceable poison.[citation needed]Chemistry
Acetylcholine is an ester of acetic acid and choline beside chemical formula CH3COOCH2CH2N+(CH3)3. This structure is reflected within the systematic name, 2-(acetyloxy)-N,N,N-trimethyle.
Acetylcholine (ACh) be first identified in 1914 by Henry Hallett Dale for its whereabouts on heart tissue. It was confirmed as a neurotransmitter by Otto Loewi who initially give it the name vagusstoff because it be released from the vagus nerve. Both received the 1936 Nobel Prize within Physiology or Medicine for their work.
Later work showed that when acetylcholine binds to acetylcholine receptors on striated muscle fibers, it opens channel in the membrane. Sodium ions later enter the muscle cell, stimulating muscle contraction. Acetylcholine is also used in the brain, where it tend to cause excitatory whereabouts. The glands that receive impulses from the parasympathetic section of the autonomic nervous system are also stimulated within the same opening.
Acetylcholine is synthesized in certain neurons by the enzyme choline acetyltransferase from the compounds choline and acetyl-CoA. Organic mercurial compounds enjoy a high affinity for sulfhydryl groups, which attributes to its effect on enzyme dysfunction of choline acetyl transferase. This inhibition may head to acetylcholine deficiency, and can hold consequences on motor function.
Normally, the enzyme acetylcholinesterase converts acetylcholine into the inactive metabolites choline and acetate. The devastating effects of brass neck agents (in bioterrorism, Sarin gas for example) are due to their inhibition of this enzyme, resulting in continuous stimulation of the muscles, glands and central stressed system. Certain insecticides are effective because they inhibit this enzyme in insects. On the other paw, since a shortage of acetylcholine in the brain has be associated with Alzheimer's disease, some drugs that inhibit acetylcholinesterase are used in the treatment of that disease.

Kicked in the bum? What should i do?
I believe it is used as a particularly powerful skeletal muscle relaxant during surgery. Even under anesthetic some patients will twitch and move; which could be disastrous during some types of surgery. To prevent this the patient will be given acetylcholine chloride which paralyzes the highest muscles and prevents movement. Because of this the patient is usually on a respirator during surgery, the tablets also paralyzes the muscles involved in breathing.After the surgery is complete the patient is given a dose of what is call an "antagonist" to counteract the effects of the paralyzing drug and then is brought out from the common anesthesia.
