The receptors/buds responsible for carrying bitter taste sensation are situated
Correct Answer: All the sides
Description: Humans have five established basic tastes: sweet, sour, bitter, salt, and umami. It used to be thought that the surface of the tongue had special areas for each of the first four of these sensations, but it is now clear that all tastants are sensed from all pas of the tongue and adjacent structures. Afferent nerves to the NTS contain fibers from all types of taste receptors, without any clear localization of types. The fifth taste sense, umami, was recently added to the four classic tastes. This taste has actually been known for almost 100 years, and it became established once its receptor was identified. It is triggered by glutamate and paicularly by the monosodium glutamate (MSG) used so extensively in Asian cooking. The taste is pleasant and sweet but differs from the standard sweet taste.Reference: Ganong review of medical physiology 23rd edition Page no: 224
