There are several types of regression in histology:
Involution: This type of regression typically occurs in tissues that undergo cyclical changes, such as the endometrium during the menstrual cycle. Degeneration: Often seen in aging tissues, degeneration involves the gradual loss of function and structure. Atrophy: This refers to the reduction in the size of an organ or tissue due to a decrease in cell size or number. It can result from disuse, denervation, or reduced blood supply.
