Degeneration Calcareous refers to a medical condition that involves the formation of calcified deposits in tissues. Antonyms for this term would include terms that denote healthy, functional tissues, free of calcification. Such antonyms could include: regeneration, rejuvenation, vitality, growth, renewal, and proliferation. These terms connote a state of health, growth, and development- the exact opposite of what degeneration calcareous signifies. As we age, our tissues lose their ability to regenerate, and calcification of tissues may occur. However, there are ways to maintain health, such as a healthy diet, exercise, and medical treatment, that may slow down the incidence of degeneration calcareous.
