The organ of taste
Taste organ (organum custus) is a peripheral part of the taste analyzer and is located in the mouth.
Taste receptors are composed of neuroepithelial cells that contain nerve branching and taste are called taste buds.
Taste buds (gemma gustatoria) are oval and are located mainly in the leaf, mushroom and circumvallate papillae of the mucous membrane of language (see "Digestive System"). In small quantities they are in the mucosa of the anterior surface of the soft palate, epiglottis and posterior pharyngeal wall.
Stimuli are perceived bulbs come to the nuclei of the brainstem, and then in the cortical end of the taste analyzer.
Receptors are able to distinguish four basic tastes: sweet perceive receptors located on the tip of the tongue, bitter - receptors located at the base of the tongue, salty and sour - the receptors on the edges of the tongue.
