What medical prefix refers specifically to the liver?

The prefix that refers specifically to the liver is derived from the Greek word "hepar," which translates to liver. This term is commonly used in medical terminology to indicate conditions or anatomical structures associated with the liver. For instance, "hepatitis" refers to inflammation of the liver, whereas "hepatomegaly" indicates an enlarged liver.

The prefixes related to the other options do not pertain to the liver. "Cost" typically relates to the ribs, "cerv" is linked to the neck or cervical region, and "sub" means beneath or under. Thus, the prefix "hept" clearly stands out as the one specifically designating anything associated with the liver.
