Each taste bud contains cells for every taste, and they're mostly found at the front of the tongue. Each cell sends signals to a specific part of the brain, creating a unique taste experience. This process is called the labelled lines model.

When we eat, molecules from the food reach our olfactory epithelium, a special area in the nose, and bind to receptors on olfactory sensory cells. These cells then send signals to the brain, allowing us to perceive the flavor. When our sense of smell is impaired, such as during a cold, our sense of taste is also affected.
