MUSCLE PHYSIOLOGY

Detailed explanation-1: -Our sense of taste can detect and discriminate various ionic stimuli, for example, Na+ as salty, H+ as sour, sugars as sweet and alkaloids as bitter.

Detailed explanation-2: -The chemical stimuli of special significance to taste are sugars (sweet), amino acids (umami), sodium chloride and other salts (salty), alkaloids (bitter) and acids (sour). Sugars and amino acids tend to be preferred, while alkaloids and acids tend to be avoided.

Detailed explanation-3: -Chapter 15The Chemical Senses Three sensory systems associated with the nose and mouth-olfaction, taste, and the trigeminal chemosensory system-are dedicated to the detection of chemicals in the environment. The olfactory system detects airborne molecules called odors.
