The combining form my/o refers to which body part?

• A. Muscle
• B. Blood
• C. Bone
• D. Nerve

Answer: (A)

The main idea here is recognizing which body part a combining form refers to. The combining form my/o denotes muscle. That means any term built with my/o points to muscle-related structure, disease, or function. For example, myopathy means a disease of the muscle, myalgia is muscle pain, and myology is the study of muscles. This is how you interpret terms: a muscle-related root paired with different suffixes or endings conveys specific meanings about muscle tissue.

In contrast, bone uses oste/o, nerve uses neur/o, and blood uses hem/o or hemat/o. So the presence of my/o signals that the term is about muscle, not bone, nerve, or blood.
