AP PSYCHOLOGY

Detailed explanation-1: -Taste bud cells undergo continual turnover even in adulthood, and their average lifespan has been estimated as approximately 10 days.

Detailed explanation-2: -Similar to other epithelial cells, taste cells turn over continuously, with an average life span of about 8–12 days. To maintain structural homeostasis in taste buds, new cells are generated to replace dying cells.

Detailed explanation-3: -Taste receptor cells (TRCs) have an average life span of about 10 days and are replaced from a population of stem cells located within the taste bud.

Detailed explanation-4: -Cells that contain the receptors for taste and smell are replaced every 10-30 days. As we age the total number of these cells decline, especially after age 70.

Detailed explanation-5: -According to animal research from 2006, our taste buds themselves turnover every 10 days, while further research from 2010 suggests that approximately 10 percent of the cells inside these taste buds turnover each day.
