The true statement about taste cells is that they are replaced every 10 to 14 days, are specialized for different taste sensations, and are found within taste buds on the tongue, except on filiform papillae which have no taste buds.
The true statement regarding taste cells is that each taste bud's taste cells are replaced every 10 to 14 days. Taste cells, also known as gustatory cells, are sensitive to specific taste sensations and are not all sensitive to every taste. These cells contain hair-like processes called microvilli that respond to chemicals in food that are dissolved in saliva.
When stimulated, these cells trigger action potentials in sensory neurons that send messages to the brain, thus allowing us to perceive taste. Taste cells are located within taste buds on the tongue, and these buds are found on three of the four types of papillae in the mouth, with the exclusion of filiform papillae which contain no taste cells.
So, taste cells have a short lifespan and regenerate frequently, which is essential for maintaining the sense of taste throughout a person's life. They are also specialized and distributed across different regions of the tongue, contributing to the ability to detect a variety of tastes.
