The misinterpreted diagram that sparked this myth shows human taste buds distributed in a "taste belt" along the inside of the tongue. Prior to this, A. Hoffmann had concluded in 1875 that the dorsal center of the human tongue has practically no fungiform papillae and taste buds, [12] and it was this finding that the diagram describes.
Taste bud. Taste buds are clusters of taste receptor cells, which are also known as gustatory cells. [ 1 ] The taste receptors are located around the small structures known as papillae found on the upper surface of the tongue, soft palate, upper esophagus, the cheek, and epiglottis. These structures are involved in detecting the five elements ...
The diagram above depicts the signal transduction pathway of the sweet taste. Object A is a taste bud, object B is one taste cell of the taste bud, and object C is the neuron attached to the taste cell. I. Part I shows the reception of a molecule. 1. Sugar, the first messenger, binds to a protein receptor on the cell membrane. II.

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The process of digestion has three ...
Lingual papillae (sg.: papilla) are small structures on the upper surface of the tongue that give it its characteristic rough texture. The four types of papillae on the human tongue have different structures and are accordingly classified as circumvallate (or vallate), fungiform, filiform, and foliate. All except the filiform papillae are ...
The gustatory nucleus is the rostral part of the solitary nucleus located in the medulla. The gustatory nucleus is associated with the sense of taste [ 1 ] and has two sections, the rostral and lateral regions. [ 2 ] A close association between the gustatory nucleus and visceral information exists for this function in the gustatory system ...
The left tympanic membrane with the malleus and the chorda tympani, viewed from within the tympanic cavity (medial). Chorda tympani is a branch of the facial nerve that carries gustatory (taste) sensory innervation from the front of the tongue and parasympathetic (secretomotor) innervation to the submandibular and sublingual salivary glands.
