Taste sensation work with smell sensation or they enhance each other. The receptors for taste are located in specialized organs called taste buds which are numerous on the surface of the epithelium covering the tongue in humans and mamals. The taste buds are also located on the papillae on the upper surface of the tongue and also on the roof of the oral cavity, the pharynx and larynx.
In humans, the chemoreceptors that detect taste are called gustatory receptor cells. About 50 receptor cells, plus basal and supporting cells, make up one taste bud. Taste buds themselves are contained in goblet-shaped papillae -- the small bumps that dot your tongue.ifferent stimuli activate different sensory receptors. Chemical stimuli activate the chemoreceptors responsible for gustatory and olfactory perceptions. Because taste and smell are both reactions to the chemical makeup of solutions, the two senses are closely related.
