Myasthenia gravis is a disease that is believed to be caused by autoimmune disorder, resulting in the loss of ACh receptors at the motor end plate of muscle fibers. Which of the following is likely to be a symptom of myasthenia gravis?

A. dehydration with headache
B. coma and loss of voluntary muscle movement
C. weakness of muscle
D. seizures and uncontrollable muscle movement

C. weakness of muscle

Explanation:

Myasthenia gravis is an autoimmune disorder where body's immune system attacks its own neuromuscular system.Antibodies destroy or block nicotinic acetylcholine receptors (ACh) which are present at neuromuscular junction. So, the neurons are not able to pass contraction signals to the muscle cells. As a result the muscles become weak. Hence the disease is characterized by weakness of muscle as evident by drooping eyes, difficulty in walking, talking and swallowing.  

I’ve personally felt invisible all my life, especially when a friend turned out to be fake and didn’t seem to take any type of interest in what i said or any type of input i said. being invisible is a terrifying feeling to experience due to the fact you feel like no one sees you and just sees you (sorry if that doesn’t make sense). it’s like a deep emptiness that no one can fill, just you; you have to fix that emptiness by yourself and you don’t really want , or in some cases want to be invisible. i can see many invisible people when they intentionally stay away from people that can potentially hurt them in any way. also, when a person intentionally breaks off a connection so they aren’t seen by people.hope it
