Which term is used to describe a condition of a gland?

The term "adenosis" specifically refers to a condition involving a gland, making it the correct choice. In medical terminology, the prefix "aden/o" pertains to glands, while the suffix "-osis" signifies a condition, usually one that is abnormal or diseased. When combined, "adenosis" indicates an abnormal condition or disease affecting a gland.

The other options do not define a condition of a gland. "Aden/o" is merely a prefix and does not describe a specific condition. "Myasthenia," on the other hand, refers to muscle weakness and is not related to glands. "Meningocele" describes a condition involving the meninges (the protective membranes covering the brain and spinal cord) rather than a glandular issue. Thus, "adenosis" is the only complete term that accurately describes a condition of a gland.
