to the nervous system and then to the brain. Scientists know less about taste than they know about the other senses. Taste - it seems simple but it isnt. Instead,
taste is mysterious. This essay will explain why it remains mysterious and what taste is all about. Literature Review One of the problems with taste is that it
is often confused with flavor. Flavor involves other senses like sight and smell. The brain interprets gustatory, tactile, olfactory, and thermal stimuli for flavor. Taste is a chemical sense
that is perceived by special receptor cells that make up the taste buds. Taste is more subjective than the other senses. Some people have actually inherited genetic traits that make
certain foods taste terrible (Dowdey, 2012). Other people have many more taste receptors than normal so that a bland food will taste just fine because of their heightened palates (Dowdey,
2012). They are called supertasters because they taste everything. Taste begins with sensation in the form of electrical impulses. Sensations are perceptions of the experience but only when
the sensation reaches the brain. Chemical stimuli activate different sensory receptors, such as the chemoreceptors (Dowdey, 2012). These are responsible for both gustatory and olfactory perceptions. So, these two
senses are closely related. In humans, gustatory receptor cells detect taste (Dowdey, 2012). One taste bud is comprised of 50 receptor cells plus basal and supporting cells. Taste buds
are in the tongue in goblet-shared papillae (Dowdey, 2012; Genetics Learning Center, 2012). These are the small bumps that cover the tongue. There is a spindly protrusion called a
gustatory hair on each gustatory receptor cell. The gustatory hair reaches the outside environment through a taste pore (Dowdey, 2012; Genetics Learning Center, 2012). Saliva mixes with molecules, goes
