What does the suffix "-sclerosis" mean?

The suffix "-sclerosis" is derived from the Greek word "skleros," which means "hard." In medical terminology, it is used to describe the hardening of a tissue or organ. This can occur in various conditions, such as multiple sclerosis, where there is hardening of the nervous tissue, or atherosclerosis, which refers to the hardening of arteries due to plaque buildup. Understanding this specific terminology is vital in the medical field as it helps in accurately describing the pathological changes occurring in tissues and organs. In contrast, the other options represent different processes: softening refers to a decrease in rigidity, growth pertains to an increase in size or number, and nourishment relates to providing nutrients essential for maintaining biological functions.
