Snemalna Knjiga Besedilo
- Are there any diseases or disorders that can affect our taste?
- Some people are born with taste disorders, but most develop them after an injury or illness. Among the causes of taste problems are :
- Head injurySome surgeries to the ear, nose, and throat (such as middle ear surgery) or extraction of the third molar (wisdom tooth)Poor oral hygiene and dental problems.
- What are the sensory stimuli of taste and how does it work?
- Receptor cells live for only 1 to 2 weeks and then are replaced by new receptor cells. Each receptor in a taste bud responds best to one of the basic tastes. A receptor can respond to the other tastes, but it responds strongest to a particular taste.
- The actual organ of taste is called the "taste bud." Each taste bud (and there approximately 10,000 taste buds in humans) is made up of many (between 50-150) receptor cells.
- What are activities that children can do to help them learn more about how taste works?
- When students have finished the taste test, reveal the identity of the food and tally the number of correct responses. A possible statement describing the difference between taste and flavor is: Taste is sensed by our tongues, whereas flavor is constructed by the brain, based on stimuli from the tongue and nose.
- give each student a spoonful of baby food in a cup and a cotton swab dipped in mint oil (e.g., peppermint, spearmint, wintergreen, or eucalyptus) or a very strong breath mint. Do not reveal the identity of the food. Students should smell the mint as they taste the food. Next, they should taste the food sample while holding their nose.
