PSYB51H3 Chapter Notes - Chapter 15: Lingual Papilla, Taste Receptor, Olfactory Mucosa
Document Summary
Taste sensations evoked by solutions in the mouth that contact receptors in the mouth that contact receptors in the tongue and the roof of the mouth that then connect to the axons in cranial nerves xii, ix and x. Molecules dissolve in our saliva and stimulate the taste receptors in our taste buds. Retronasal olfactory sensation the sensation of an odor that is perceived when chewing and swallowing force an odorant in the mouth up behind the palate into the nose. Such odor sensations are perceived as originating from the mouth, even though the actual contact of odorant and receptor occurs at the olfactory mucosa. Flavour the combination of true taste (sweet, salty, sour, bitter) and retronasal olfaction. Molecules release dinto the air inside our mouths as we chew and swallow food travel up through the retronasal passage into the nose, where they move upward and contact the olfactory epithelium.
