Relating to a condition that causes weakness in the muscles, often due to a problem with the connection between nerves and muscles.
The patient was diagnosed with a myasthenic condition that affected her ability to walk.
Myasthenic → It is formed from "myo-" (from Greek "musculus", meaning muscle) and "asthenia" (from Greek "astheneia", meaning weakness). The word "myasthenic" refers to a condition characterized by muscle weakness.
Think of 'muscle' ('myo-') combined with 'weakness' ('asthenia') to remember that myasthenic describes a condition of muscle weakness.
