Acetylcholine receptors at neuromuscular junctions are affected in MG. MG is an autoimmune disorder in which the body produces antibodies against its own protein, the acetylcholine receptor. These antibodies block the receptor, preventing the binding of acetylcholine and inhibiting the function of the receptor, which is to initiate a depolarization in muscle cells that will lead to contraction. Fewer available acetylcholine receptors means greater stimuli, i.e. more acetylcholine has to be released to cause a contraction. This manifests physically as serious weakness resulting from inability to move muscles at will. The name of the disease describes the symptoms quite well (my-, muscle; -a-, without; -sthenia, strength; gravis, heavy, serious).

What would be the reason of removing the thymus gland of myasthenia gravis patient?
Mysthenia Gravis (MG) is a disease mediated by antibodies which attack the receptors on muscles and decreases their ability to contract (to be stimulated to contract actually). The thymus gland is an organ involved with the maturation of T-lymphocytes which are involved in the production of antibodies. An association with tumors of the thymus gland and the onset of myasthenia gravis was noted and removal of thymomas has been shown to be effective in treating MG. Extending from this knowledge surgeons have removed normal appearing thymus glands in patients with MG and this has been proven in some large studies to be effective in decreasing the severity of myathenia gravis over the long term.
Can someone 14 years old get myasthenia gravis?
Yes. I was diagnosed with Myasthenia Gravis at age 15.
Why aminoglycosides cause weakness in myasthenia gravis?
Aminoglycosides inhibit the release of acetylcholine from the motor nerve. Myestenia gravis patients are more susceptible to this effect. So these drugs are to be avoided in myestenia gravis patients.
Can ophthalmoplegia happen with myasthenia gravis?
Yes
What is a chronic progressive neuromuscular disease that is characterized by extreme muscular weakness and progressive fatigue?
Myesthena Gravis Various forms of motor neurone disease (ALS being one in the states) Persistent long term low testosterone MS That's to name just a few.
Myasthenia gravis why is atropine given?
it affects the receptors
When the immune system produces antibodies which destroy acetylcholine receptors this disease is called?
Myasthenia gravis.
Is curare poisoning affected by the motor end plate or the axon terminal?
myasthenia gravis is affected by the motor end plate .it is a autoimmune disorder caused by the formation of circulating antibodies to the nicotinic A-ch receptors present in motor end plate.
A deficiency of ACh receptors in a motor end plate would cause and is called?
myasthenia gravis
Which groups of people are affected by myasthenia gravis?
Myasthenia gravis occurs in all ethnic groups and both genders. Initial studies showed women are more often affected than men but as the population ages men are more affected than women.
What happens when acetylcholine receptors are blocked?
There are several compounds and drugs that may block acetylcholine receptors. They are collectively known as cholinergic antagonists.
How is neostigmine chemically used to treat myasthenia gravis?
Neostigmine is a competitive irreversible inhibitor of Acetylcholinesterase (AChE), an enzyme responsible for breaking down acetylcholine (ACh). Myasthenia gravis is caused by the body producing too little ACh receptors. As stimulating the ACh receptors is needed for nervous transmission, the nerve signals cannot be transmitted causing muscle weakness and fatigue. Neostigmine is hence used to inhibit AChE so that less ACh gets broken down. This leads to more ACh binding to the ACh receptors causing muscular contraction.
Which chronic autoimmune disease produces serious weakness of the voluntary muscles?
Myasthenia gravis is an autoimmune disease marked by muscle weakness and fatigue. The symptoms are activated when the immune system produces antibodies that interfere with the transmission of nerve signals to skeletal (voluntary) muscle. As a result, the affected muscles cannot contract normally.
Is Doryx contraindicated in Myasthenia gravis?
Doxycycline is not contraindicated in myathenia gravis.
What is a disease that can affect the thymus gland?
Scientists beleive that disorder of thymus gland can cause Myasthenia Gravis , a disease of severe muscle weakness . In this antibodies are produced against Ach receptors of neuro-muscular junction .

When was Advanced Gravis Computer Technology created?
Advanced Gravis Computer Technology was created in 1982.
