In medical terminology, which prefix indicates "cell"?

The prefix that indicates "cell" is derived from the Greek word "kytos," which means "cell." Thus, the prefix "cyt/o" is specifically used in medical terminology to denote cell-related concepts. For example, terms like "cytology" refer to the study of cells, and "cytoplasm" refers to the material within a cell excluding the nucleus.

In contrast, "cyst/o" pertains to a cyst or sac-like structure, "dermat/o" refers to the skin, and "delus/o" does not have a common medical term connection to cells. These prefixes have distinct meanings and indicate different structures in the body, further emphasizing that "cyt/o" is the correct choice for anything relating to cells.
