What does the term "-spasm" indicate in medical terminology?

The suffix "-spasm" in medical terminology specifically refers to an involuntary muscle contraction. This term is derived from the Greek word "spasmos," which means a sudden, involuntary contraction of a muscle or a group of muscles. Understanding this terminology is especially important in the context of various medical conditions where muscle spasms may occur, such as in cases of cramping, seizures, or other neuromuscular disorders.

In contrast, the other options refer to different processes: "abnormal flow" relates to conditions involving altered circulation or drainage, "hardening of tissues" typically refers to sclerosis or similar pathological changes, and "discharge of fluids" involves secretion or excretion processes that do not pertain to muscle contractions. Recognizing the specific meanings of suffixes like "-spasm" allows for precise communication in clinical and medical contexts.
