Nerve cells which register the sensation of taste and transmit it to the brain are arranged in a bulb-like manner. The nerve ends may be compared to the roots, while the layers of the bulb represent the reaction controls, with built-in amplifiers. To complete the illustration, in the place of the bulb’s top, there are very fine hairlike nerves that register the taste sensation.

These nerve bulbs are called taste buds, because scientists compared them to the literal buds. An adult has about 3,000 of them. But did you know that we humans probably have fewer sensations of taste when eating our food than, for example, antelopes, which have about fifteen times as many taste buds as a human? If we had as many as these animals it would be much easier for us to differentiate between healthy nourishing food and that which is harmful. Thus animals are more capable than humans in distinguishing what is good for them and what is not.
