Gustation Anthony J Greene

Smell & Taste In sea-borne organisms, smell and taste are the same - some reptiles smell with their tongues Close relationship between smell and taste Anthony J Greene

Taste Diet regulation Last chance to detect a poison prior to ingestion Anthony J Greene

Anatomy of Taste Papillae Circumvilliate Folliate Filliform Fungiform Anthony J Greene

Anatomy of Taste Taste Receptors Taste Buds occur on the soft palate and on some Papillae - Foliate, Circumvallete, Fungiform, Filliform (no taste buds) About 10,000 taste buds Anthony J Greene
