Muscarinic receptors...?
827753
Both A) and B) appear to be true, unless I am overlooking something...\n\nMuscarinic receptors are G-protein linked receptors that are activated by acetylcholine. That makes A) true.\n\nBoth nicotinic and muscarinic ACh receptors are located on the postganglionic cells in both the sympathetic and parasympathetic nervous systems. However, neither ACh receptor is located on the preganglionic cells of either the sympathetic or parasympathetic systems. So, since they are only located on the post and not the pre, I would consider B) to be false.\n\nMuscarinic receptors do not always produce an excitatory response. They are G-protein linked, so they can cause a wide variety of activities within different cells. Nicotinic, on the other hand, always involve the opening of a sodium channel and are therefore always excitatory. C) is false.\n\nNicotinic control sodium channels, so D) is false.\n\nNorepinepherine does not activate ACh, so E) is false.\n\nIn my opinion, you could make an argument for either A) or B) being true. Muscarinic receptors are located on the surface of ganglion cells in both the sympathetic and parasympathetic nervous systems, but only on the postganglionic neurons. The ganglionic neurons only release ACh.\n\nA) is therefore the "safe" choice.

(D) norepinephrine.\n\nNote that  (B) and (C) refer to the same substance; "epinephrine" is the term used by American doctors, while most of the rest of the world prefers the name "adrenalin(-e)."   Also, Acetylcholine (A) is the counterpart neurotransmitter in the parasympathetic branch.

my wife has the same problem and Imitrex damn near killed her. there are some herbs that can help, if you would like info on them contact me direct: widowmaker54@yahoo.com\nI am an herbalist, and my information is free.

IF you want to know about tranquilizers have a look at wikipedia, there they name some of them, otherwise ask your practitioner for advice and research tips.\n\nI wouldn't dare to give this information via an open Forum, as I am always suspicious if the real reason was mentioned.

This is a question for a doctor, not yahoo!!\n\nI wouldn't worry myself, since its been a few days and you haven't mentioned any other side effects, but if you're unsure, see a doctor!

If you suffer from serious migranes and excedrin, tylenol, or advil don't work. Go to your physican and get a prescription for Imitrex. It's like a super pill. You're migrane is gone in about a 1/2 hour. I've been on them for a few years, and my migranses have gone from every 2 days and having to go to the hospital for a pain med. drip to having maybe 2 migranes a month and all I have to do is pop an IMITREX drink 2 glasses of water and relax for 45 minutes

In the whole autonomic nervous system there are 3 main hormones/neurotransmitters\n\n1)Adrenaline\n2)Noradrenaline\n3)Acetylcholine\n\nAdrenaline/Noradrenaline both stimulate the same receptors (alpha and beta adrenergic) but to different extents. (Think ADRENaline = ADRENergic. Both adrenaline and noradrenaline have ADREN in their name) AcetylCHOLINE stimulates CHOLINErgic receptors\n\nAll these transmitters are found in both the sympathetic and parasympathetic branches of the autonomic system

Thanks for your answer on my question. Just returning the favour. I too suffer from tremors and found these webpages to be useful.\n\nhttp://my.webmd.com/content/article/40/4021_105.htm\nhttp://my.webmd.com/content/article/40/4021_103.htm\nhttp://www.emedicine.com/neuro/topic129.htm\n\nFeel free to contact me.

I think you will find what you need here:\n\nhttp://faculty.washington.edu/chudler/introb.html\n\nIt is a good but simple site on neuroscience.\n\nThere was an identical question in Yahoo Answers since yours; I answered that in the same way.  Check it out for other help.

D) beta-2\n\nI am not 100% positive, but I do know that beta-2 receptors are only located in liver and skeletal muscle tissue. Considering that these are the only locations where glycogen break down occurs, I would assume that they mediate it.\n\nBeta-1 receptors are located in cardiac muscle tissue.\n\nAlpha-2 receptors are used to inhibit (nor)epinephrine release via negative feedback.\n\nI don't recall what alpha-2 receptors do, but I am pretty sure they aren't predominately responsible for glycogen break down.\n\nCholinergic receptors are ACh receptors.\n\nHope this helps!

The quantity of neurotransmitters in the terminals is kept relatively constant and independent of nerve activity by tight regulation of neurotransmitter formation. Regulation varies among neurons and is achieved by modifying precursor uptake or the activity of enzymes involved in neurotransmitter synthesis or destruction. Stimulation or blockade of postsynaptic receptors can decrease or increase presynaptic neurotransmitter synthesis.\n\nNeurotransmitters diffuse across the synaptic cleft, bind briefly to receptors, and activate them, causing physiologic responses. Depending on the receptor, the response may be excitatory (ie, initiating a new action potential) or inhibitory (ie, inhibiting the development of a new action potential).\n\nThe neurotransmitter-receptor interaction must be terminated quickly so that the same receptors can be rapidly activated repeatedly. The neurotransmitter is quickly pumped back into the presynaptic nerve terminals by active processes (reuptake), is destroyed by enzymes near the receptors, or diffuses into the surrounding area and is destroyed.\n\nAbnormalities of neurotransmitter synthesis, storage, release, or degradation or changes in the number and affinity of receptors can affect neurotransmission and cause clinical disorders

well the best is the old stacher3 good luck finding them i been taking them for lot of years i take stacker3with chitosen they work great good luck

lots of them will but they aren't too good for ya.  tylenol pm will knock you out for a while.  i am on rozerem and it works great!  you should go get a script for it.

I think I know where you're headed with this....\nIf you want a bit more detail on the relationship between light and neurotransmitters, Google this term:\nPineal Gland\nRead everything you can find.

all three act together in the regulation of breathing.\n\nthe chemoreceptors are located at the aortic arch and functions as peripheral receptors that will send information about the level of oxygen and carbon dioxyde in the blood to the medullary center. The respiratory center in the pons and medulla will send information to the respiratory muscles.\n\nj receptors, located at the small bronchi is connected to the cranial nerve X (n. vagus). this is a form of autonomic regulation
