Understanding how muscles move is important to understand Myasthenia Gravis
How muscles move:
Our brain sends signals to our muscles.
These signals travel down to our nerves.
Nerves don’t touch muscles directly.
There is a space between the muscles and nerves called the neuromuscular junction (NMJ).
The important chemical:
When the signal gets to the nerve ending, it releases a chemical called acetylcholine.
Acetylcholine travels across the space to the muscle.
It connects to places called receptor sites on the muscle.
When enough receptor sites have acetylcholine, the muscle moves.
