Which prefix means muscle?

Which prefix means muscle?

• A. Muscul(o)
• B. My(o)
• C. Myel(o)
• D. Nas(o)

Answer: (A)

Muscul(o)- is the combining form used specifically to indicate muscle, coming from Latin musculus and appearing in terms like musculature and muscular. This makes it the clear prefix for anything related to muscle when forming anatomical terms. In contrast, myel(o) refers to bone marrow or the spinal cord, and nas(o) refers to the nose, so they don’t denote muscle. While myo- is another prefix sometimes used for muscle in different terms, the form used here to signal muscle is muscul(o).
