Atrophy is defined as

Explanation:
Atrophy is the wasting away of tissue or an organ due to a decrease in cell size or number, leading to a smaller, weaker mass. This change can occur with aging or as a result of disuse, malnutrition, nerve injury, or chronic disease. In muscles, for example, lack of use causes shrinkage of muscle fibers and reduced strength, while nerve damage can cause denervation atrophy. This concept is distinct from a malformation, which is a developmental defect; from lack of symmetry, which refers to uneven structure; and from gait, which is a walking pattern.
