http://www.cardiff.ac.uk/biosi/staffinfo/jacob/teaching/sensory/taste.htmltaste is mainly through smell and altough there are tons of tastebuds on the tongue there are 2500 taste buds on the epiglottis, soft palate, laryngeal and oral pharynx.
This is intersting for all of us who have had partial or full glossectomies. I always am stumpe for how to explain to people that although I will never be able to taste like I did before I still do taste a lot of my food.
