Does acetylcholine have anything to do with how vision works?

Does acetylcholine have anything to do with how vision works?

Yes, in a way.: Acetylcholine transmits signals from nerves to muscles, such as those that control the pupil size and the focusing power. When these muscles are activated, the pupil will get smaller and the focusing muscles will contract, enabling the eye to see up close, as for reading. These two actions can also normally occur separately. Acetylcholine is sometimes used during eye surgery. ...Read more

Vision (Definition)

Vision is a feature of a person's brain that allows him to see. He must have normal eyes, optic nerves (that stretch from the eyes to the back of his brain), and visual cortex (the vision center in the brain), in order to see properly. An ophthalmologist is a ...Read more

Does acetylcholine result in blurry vision?

Does acetylcholine result in blurry vision?

Yes: Acetylcholine is a neurotransmitter. It behaves like a key activiting receptors "keyhole" diseases like myasthenia gravis affect the receptor "keyhole". Acetylcholine in its pure form only used inside the eye to constrict the pupil after cataract surgery. Other drugs that mimic its behavior include pilocarpine. Pilocarpine makes pupil smaller and your vision blurry. Great question. ...Read more

What happens to your vision when you lack brain chemicals such as acetylcholine and serotonin?

What happens to your vision when you lack brain chemicals such as acetylcholine and serotonin?

Consult Neurologist!: Complex answer depending on exact levels of deficiency of these vitally important neurologic "neurotransmitters" chemicals that control specific brain and muscle functioning. Multiple diseases such as depression and neurologic or muscle disorders may result from dramatically abnormal high or low levels of these chemicals in the body/central nervous system. ...Read more

What do acetylcholine receptors agonists do and what are they used for?

What do acetylcholine receptors agonists do and what are they used for?

Different things: Agonists stimulate receptors while antagonists inhibit them. Most often we use the antagonist drugs in treating different diseases. However, those conditions that decrease sputum, sweat or tear production are sometimes treated with an agonist. Pilocarpine (an agonist) is used to treat glaucoma but by a different mechanism as mentioned above. ...Read more

What are the effects of too high/too low acetylcholine levels on the muscle during swimming practice?

What are the effects of too high/too low acetylcholine levels on the muscle during swimming practice?

Muscle fatigue: Acetylcholine is a neurotransmitter that can help a nerve impulse to jump the synaptic cleft
(the gap that separates the nerve ending from the muscle fibre) and initiate muscular contraction. When levels of acetylcholine are low, the muscles become fatigued. ...Read more

How does the human brain produce neurotransmitters such as acetylcholine?

How does the human brain produce neurotransmitters such as acetylcholine?

ACH synthesis brain: Ach in the brain is produced from acetyl-coa (from glucose metabolism) & from choline, which is actively transported across blood-brain barrier. Most dietary choline comes from phosphatidyl choline (major phospholipid in membranes of plants&animals) acetyl-coa & choline are independently synthesized in neuron cell body & transported along axon to synapse where they are joined into acetylcholine. ...Read more

How do I increase acetylcholine, dopamine and serotonin levels naturally?

How do I increase acetylcholine, dopamine and serotonin levels naturally?

Think yours are low?: This is about the nervous system. What makes you think your "levels" are low? Neurotransmitters don't HAVE "levels". They don't just float around or circulate in blood. They're made in the terminal boutons of neurons, released into the synaptic cleft, & immediately either recycled & replaced or taken back up. Neurochemistry isn't just a New Age fad. REAL knowledge is power. Go arm yourself. ...Read more

If I have acetylcholine deficiency will be able to lift weights as much as a normal person can? What if I have higher acetylcholine will I be able to lift more than a normal person?

My thoughts: Not clear what you really want. Acetylcholine does mediate neuromuscular transmission, and if malfunctioning, due to diseases, such as myasthenia, spider bites, botulism, fertilizer sprays. Level drops in brain due to alzheimers, but does not affect muscle. Not sure whether you are asking about supplements for muscle growth, but this does not involve ach. ...Read more

How does the acetylcholine affect the blood vessels?

How does the acetylcholine affect the blood vessels?

ACH effect on BV: M3 muscarinic ach receptors are located in smooth muscles of blood vessels. Because they're gq-coupled & mediate increase in intracellular calcium, they typically cause contraction of smooth muscle (as in bronchi). But activation of m3 on vascular endothelial cells causes increased synthesis of nitric oxide, which diffuses to adjacent vascular smooth muscle cells and causes their relaxation. ...Read more

If acetylcholinesterase is not present to remove acetylcholine, the muscle is in contraction. What is the name of the disorder/disease?

If acetylcholinesterase is not present to remove acetylcholine, the muscle is in contraction. What is the name of the disorder/disease?

Acetylcholinesterase: Is always present. Acetylcholine doesn't just cause muscle contraction; it's essential in the CNS as well. You can't have absence in one place & presence in the other. Our bodies don't work that way. An absence of acetylcholinesterase is not compatible with life. ...Read more

I’ve read that anticholinergic drugs block acetylcholine, causing mental deterioration. Is this a concern if you're not eldery? Taking amitriptyline 25

Minimal concern: Correct. Amitriptylline has anticholinergic properties. It's been around for many years and is a very useful drug for a variety of medical problems and also relatively inexpensive. 25 mg is a low and well tolerated dose. Cognitive changes in the elderly a concern given age-related mental decline, other diseases, and the fact that they are often on other meds with anticholinergic effects- additive. ...Read more

Tested for acetylcholine receptor ab panel; both binding and blocking were 0, but modulating came back at 10. Does this mean I have myasthenia gravis?

Tested for acetylcholine receptor ab panel; both binding and blocking were 0, but modulating came back at 10. Does this mean I have myasthenia gravis?

AchRAntibodies: Binding antibodies are the most sensitive--they are positive in over 80% of ms patients. Blocking antibodies are positive in about half. Modulating antibodies alone don't support the diagnosis and have a lot oof false positives. In summary the achreceptor antibody panel does not suggest that ou have ms>. ...Read more

Why does acetylcholine, an inhibitory neurotransmitter, cause the adrenal glands to release stimulatory hormones?

Not correct: Hi. Acetyl choline (ACh) is not an inhibitory neurotransmitter. The sympathetic nervous system uses ACh as the neurotransmitter in the sympathetic ganglia (the 1st synapse outside the CNS). Usually that's from one neuron to another, but in the adrenal medulla, the cells are really the second neuron, but they release their contents (catecholamines) into the blood, not onto an organ (like the heart) ...Read more

Can supplementing with acetyl L- Carnitine raise acetylcholine all over the body or does it only affect ACh levels in the brain?

Can supplementing with acetyl L- Carnitine raise acetylcholine all over the body or does it only affect ACh levels in the brain?

Probably neither: Unless you were severely deficient of it previously, supplementing with it is getting peed out in your urine. This supplement is like many on the market right now- they promise you all kinds of things they can't back up - and don't have to because they are classified as foods, not as medicines. So show me a good study that someone of normal diet and health actually increases brain levels with this ...Read more

Can you tell me in myasthenia gravis why do you give an acetylcholine esterase inhibitor instead of a direct receptor agonist?

Because...: If you provide an agonist your muscles will contract continually. The acetylcholine esterase inhibitor prolongs the life of acetylcholine released naturally from your motor nerves so you only have muscle contraction when your brain orders it. ...Read more
