Which prefix denotes muscle?

Which prefix denotes muscle?

• A. Myo-
• B. Myos-
• C. Mys-
• D. My-

Answer: (D)

Muscle is indicated by the combining form myo-, which comes from Greek and is attached to roots to form muscle-related terms. This prefix is used widely across many medical terms, such as myopathy (disease of muscle), myology (study of muscles), and myocyte (a muscle cell). That ubiquity makes myo- the standard prefix for muscle. The form myos- does appear in some terms (for example, myositis), but it’s a more specific, variant form rather than the general prefix for muscle. Mys- and my- aren’t standard prefixes used to denote muscle in medical terminology, so they aren’t the typical way to indicate muscle.
