So, flavour doesn’t come from the taste buds. Many fruits are sweet, but it’s difficult to tell them apart from that signal itself. Knowing something is sweet doesn’t give you flavour. The point of this video, is that the taste buds, don’t do very much. Some areas can be more sensitive to some stimuli, but that old model is not correct. This is the human tongue, and just to point out, all taste sensations can arise from all regions of the tongue, that tongue map that you may have seen when you were little, with sweet in the front and sour on the sides, is a lie. Certain disorders, including Parkinson’s, Alzheimer’s, multiple sclerosis, and Bell’s palsy, can cause impaired sense of taste, so it is important to get examined by a doctor if you’re experiencing a prolonged loss of taste.The 2000-10000 taste buds lining the tongue and parts of the mouth are receptors that predominantly only send one of 5 basic messages to the brain: salty, sour, bitter, sweet and umami, which is somewhat savory, and this is it.You might be asked to compare the taste of different chemical concentrations by sipping them and then spitting them out, or chemicals may be applied directly to the surface of your tongue.
The otolaryngologist will examine your ears, nose, throat, and mouth and perform a taste test to determine the lowest concentration of taste quality that you’re able to detect.If you experience loss of taste that isn’t attributable to a cold or to ageing, you should ask your doctor for a referral to this specialist, who can diagnose the extent of your taste loss and help you find a treatment for the underlying condition.
An otolaryngologist, more commonly known as an ENT (ear, nose, and throat) doctor, is a specialist in problems related to the ears, nose, throat, mouth, and larynx.
