Quizplus · Accepted Answer

Hypertrophy is the increase in size of muscle cells, which occurs as a result of regular exercise such as lifting weights. Hyperplasia refers to an increase in the number of cells, which is not typically observed in skeletal muscle. Neoplasia is the development of a new, abnormal growth, which is not related to muscle size. Metaplasia is the transformation of one cell type into another, which is not related to muscle size. Atrophy is a decrease in the size of muscle cells, which occurs with disuse or aging, and is the opposite of hypertrophy.
