Voluntary muscles are the ones that are under your conscious control. You tell your legs to move and they usually follow command right? They just move without you putting much thought into it. Well with MG the message from the brain that says “move” isn’t able to be delivered to that leg/muscle.
The Science Breakdown:
In order for the muscle to contract; enough of the receptor sites at the neuromuscular junction of a muscle have to be activated. Individuals with MG’s bodies create antibodies that block and destroy those receptors. Ultimately there aren’t enough receptor sites available to receive the message and the result is a crappy signal which equals weakness.
Antibodies are supposed to fight and kill the bad things that get into our bodies like bacteria and viruses. People with MG’s antibodies didn’t get the memo and instead they attack the body.
My body is attacking itself.

Signs & Symptoms:
- Droopy eyelids (also called ptosis)
- Blurry or double vision
- General weakness
- Difficulty swallowing and chewing
- Slurred speech
- Difficulty breathing
Some people may or may not present with some of these symptoms. This is the unique quality of MG. Myasthenics are often called Snowflake warriors. You’ll never see two of the same snowflakes; every snowflake has a different shape, size, & uniqueness. The same logic can be applied to Myasthenics.
