Myocardium is the cardiac or heart muscle that provides the force of contraction to eject blood; muscle type with many mitochondria that is dependent on a constant supply of oxygen.
Myoclonus refers to a neurologic movement disorder characterized by brief, involuntary, twitching or "shock-like" contractions of a muscle or muscle group. These jerk-like movements may be accompanied by periodic, unexpected interruptions in voluntary muscle contraction, leading to lapses of sustained posture (known as "negative myoclonus").
