What is described by the suffix '-sclerosis'?

The suffix '-sclerosis' refers to an abnormal hardening of body tissue or organs. This term often appears in medical terminology related to various conditions that involve hardening due to factors such as inflammation, fibrosis, or other pathological changes. For example, multiple sclerosis is a disease characterized by the hardening of nerve tissue, while atherosclerosis refers to the hardening of the arteries due to plaque buildup.

Understanding this suffix is crucial in medical contexts, as it helps to accurately describe the changes occurring within the body. This knowledge aids in diagnosis, treatment planning, and communication among health professionals. Other choices, such as narrowing, enlargement, or painful conditions, do not pertain to the definition of '-sclerosis,' thus clarifying why the correct interpretation focuses on abnormal hardening.
