What does the suffix "-osis" indicate in medical terminology?

The suffix "-osis" in medical terminology indicates a condition of or a disease process. This suffix is commonly used to describe various states or conditions affecting a particular organ or system. For example, "dermatosis" refers to a condition affecting the skin, and "nephrosis" pertains to a kidney condition.

The use of "-osis" signals that there is an abnormal or diseased state rather than simply a normal physiological condition. It is important to understand this terminology as it helps healthcare professionals describe and categorize illnesses, facilitating better communication and treatment planning.

In contrast, the other options refer to different meanings: one suggests an act of bursting forth, another indicates similarity or resemblance, and the last option represents a specific medical event (stroke or paralysis). None of these adequately capture the essence of what "-osis" signifies within the context of medical conditions.
