Read here about a sensory capability and its treatment in the comprehension of scale.

Overview


The human sense of taste is a form of chemoception. Although the sense of taste is an aggregation of chemoceptor signals, this sense does not scale. In other words, no one considers the taste of a galaxy as opposed to the taste of a paramecium.

About Taste


Taste or gustation is one of the two main "chemical" senses. There are at least four types of tastes that "buds" (receptors) on the tongue detect, and hence there are anatomists who argue that these constitute five or more different senses, given that each receptor conveys information to a slightly different region of the brain[citation needed]. The inability to taste is called ageusia.

The University of Maryland School of Medicine announced in 2010 that bitter taste receptors had been discovered on smooth muscle in human lung bronchi. These smooth muscles control airway contraction and dilation - contrary to expectation, bitter substances such as quinine or chloroquine opened contracted airways, offering new insight into asthma.
Taste is not the same as flavour; flavour includes the smell of a food as well as its taste.
