Question

which of these lettered structures serve as the receptor cells for taste? a section of a taste bud. the taste bud consists of a group of long semilunar cells located in an unorganized dense layer of tissue. a bundle of threads enters this group from the left side where the threads branch. the taste bud has a small opening on the right side. letter 'a' refers to the thread. letter b refers to one of two small cells located near the place where the threads enter the group. letter c refers to the semilunar cells of the group. letter d refers to the opening. a b c

Answer 1

The receptor cells for taste in a taste bud are referred to by letter 'c', representing the semilunar cells or gustatory cells that activate when chemicals from food bind with them. These taste receptor cells are responsible for transmitting taste information to the brain.

Step-by-step explanation:

In the given description of a taste bud, the receptor cells for taste are referred to by letter "c", which denotes the semilunar cells of the group. These taste receptor cells are also known as gustatory cells, and they make contact with chemicals (tastants) in food through tiny openings on the surface called taste pores. When these chemicals bind with the taste receptor cells, they generate nerve impulses that travel to the central nervous system (CNS), resulting in the perception of taste.

The letter "a", which refers to the threads, most likely represents the sensory nerves that transmit information regarding taste to the brain. Letter "b" refers to the support cells, and letter "d" refers to the taste pore, which is the small opening where tastants enter to interact with the microvilli of the taste receptor cells.

Taste buds are located on the tongue and are housed within structures called papillae. They have a life cycle of about 10 to 14 days before being replaced, ensuring that our sense of taste remains functional even if some taste cells are damaged.
