Quizplus · Accepted Answer

Myoglobinuria is named for the principal manifestation of the condition-an excess of myoglobin (an intracellular muscle protein) in the urine. Muscle cell damage releases the myoglobin. The most severe form is often called crush syndrome. Less severe and more localized forms of muscle damage are called compartment syndromes.
