What does "my/o" stand for in medical terminology?

The term "my/o" in medical terminology specifically refers to muscle. This prefix is derived from the Greek word "mys," which means muscle. It is commonly used in various medical terms related to muscle tissue, muscle disorders, and muscle physiology. For instance, "myopathy" refers to a disease of the muscle, and "myocardium" refers to the muscular tissue of the heart. Understanding this root can greatly enhance the comprehension of medical terms related to the muscular system and its functions. The other options do not relate to muscle and thus do not fit the definition associated with "my/o."
