ANS: MYASTHENIA GRAVIS
It is an autoimmune disease which
is characterized by muscle weakness that starts with exercise and resolves at
rest.Ptosis (drooping of eyelids) is common characterized by blurred vision due
to affected eye muscles that control the eye movements. Antibodies target the acetylcholine
receptors by altering or destroying them at the neuromuscular junction, hence contraction
of the muscles does not take place, and there are fewer acetylcholine receptors available so the muscles receive fewer nerve signals.
