Many taste-bud cells are replaced roughly every ten to fourteen days, so taste is a living sense with constant upkeep.

Why it matters

The idea in context

Taste buds contain cells that detect sweet, salty, sour, bitter and umami signals. Many of those cells turn over quickly, which helps the mouth recover from ordinary wear. For a personal comparison, the tongue that tastes today’s coffee is maintained more often than you imagine. The lesson: sensation depends on repair.

Aynı kart, başka bir dilde.

Birçok tat tomurcuğu hücresi yaklaşık on ila on dört günde yenilenir; yani tat, sürekli bakımı olan canlı bir duyudur.

Tat tomurcukları tatlı, tuzlu, ekşi, acı ve umami sinyallerini algılayan hücreler içerir. Bu hücrelerin birçoğu hızla yenilenir; bu da ağzın günlük yıpranmadan toparlanmasına yardım eder. Bugünkü kahveni tadan dil, sandığından daha sık bakım görür; duyular bile onarıma dayanır.
