Humans possess taste receptor cells in various parts of the body such as the gut, throat, and upper esophagus. However, it is interesting to note that only the receptors located on the tongue send taste signals to the brain. This highlights an intriguing aspect of human physiology, showing that while our body can detect taste in multiple locations, the tongue is the primary communicator of this sensory information to our brain.

In her book "Gulp: Adventures on the Alimentary Canal," author Mary Roach explores these fascinating elements of human anatomy. The distinction between where taste is detected and where it is processed underlines the complexity of our digestive and sensory systems, shedding light on the way we experience flavor and nutrition.
