Chemical Senses Taste and Smell PowerPoint Presentation free Biology Diagrams The taste system, acting in concert with the olfactory and trigeminal systems, indicates whether food should be ingested. Once in the mouth, the chemical constituents of food interact with receptors on taste cells located in epithelial specializations called taste buds in the tongue. The taste cells transduce these stimuli and provide additional information about the identity, concentration

Anatomy & Physiology Biology Diagrams
The sense of taste relies on well-defined neuroanatomical structures, namely, the taste buds and afferent nerve fibers. Taste buds are clusters of 50-100 neuroepithelial cells located throughout the oral cavity, including the epiglottis and larynx. They are responsible for the initial transduction p โฆ
Taste is a chemical sense. The sensory experience is produced by stimulation of specific receptors in the oral cavity. The gross anatomy (peripheral and central nervous system) of taste, microscopic and ultrastructural morphology of taste buds, physiology of taste (modalities, distribution of taste sensations, electrophysiology of the receptors, mechanism and intensity of stimulation, and The sense of taste is only partly conveyed by the tongue.The sense of smell also has a significant role to play. Odorants, airborne odor molecules, are inhaled through the nose and make contact with the olfactory epithelium that is coated with a range of olfactory receptors found on olfactory cilia of sensory cells. These chemical signals are then transduced into electrical ones within the
Taste and Smell Biology Diagrams
Taste and smell work together and are hard to separate from each other, which is why holding your nose can sometimes reduce the nasty taste of a dose of medicine. Within each papilla are found a hundred or so taste buds; each of these taste buds comprises 30-100 taste receptor cells and basal cells. Basal cells are glia-like cells which provide
