Q

What is the effect of Myasthenia Gravis on the neuromuscular junction?

A

Decreased functional post-synaptic ACh receptors

This leads to muscle weakness and rapid exhaustion of voluntary muscles.

Q

What is the difference between Myasthenic Crisis and Cholinergic Crisis?

A
  • Myasthenic Crisis: Drug resistance or insufficient therapy
  • Cholinergic Crisis: Excessive anticholinesterase treatment
