And each tastant is sensed differently.

每种味道都有不同的感觉。

Taste begins with taste receptor epithelial cells, rather than nervous cells, where tastants bind to receptors that trigger action potentials to four different cranial nerves that tell you: PIZZA.

味觉始于味觉受体上皮细胞，而不是神经细胞，在神经细胞中，味觉受体与触发动作电位的受体结合，这四种不同的脑神经告诉你：这是 PIZZA。

In order to taste a bite of pizza, those food chemicals, or tastants, must dissolve in saliva so they can diffuse through those taste pores, and bind to receptors on those gustatory cells, and then trigger an action potential.

为了品尝一口披萨饼，这些食物化学物质或味道剂，必须溶解在唾液中，这样它们才能通过这些味觉毛孔扩散，并与味觉细胞上的受体结合，然后触发动作电位。
