In the fungiform papillae throughout the dorsum of tongue. In the circumvallate papillae at junction of dorsum and base of tongue. Taste buds are also located in the palate, epiglottis, larynx and esophagus.> Taste sensation are carried by: From Ant 2/3rd of tongue-- through chorda tympani branch of facial nerve. Post 1/3rd of tongue--lingual branch of 10th nerve. Afferents from palate travel with the GSPN to the geniculate ganglion and thence via the facial nerve to brain stem. From larynx, epiglottis and esophagus -- Through internal branch of Sup. Laryngeal nerve of vagus.
