Which prefix refers to something related to a gland?

The prefix that refers to something related to a gland is indeed "aden/o." This prefix is derived from the Greek word "aden," which means gland. It is commonly used in medical terminology to denote structures or conditions associated with glands. For example, terms like adenoma (a tumor originating in a gland) and adenitis (inflammation of a gland) utilize this prefix to indicate their glandular connection.

On the other hand, the other prefixes represent different meanings. "Adip/o" relates to fat, "albin/o" pertains to a lack of pigmentation or color (often used to describe conditions like albinism), and "aut/o" refers to self or own (as in autoimmune diseases). Understanding the meaning of these prefixes helps in accurately interpreting medical terms and their relationships to specific body systems or structures.
