Humans detect taste with taste receptor cells. These are clustered in taste buds and scattered in other areas of the body. Each taste bud has a pore that opens out to the surface of the tongue enabling molecules and ions taken into the mouth to reach the receptor cells inside.1  salty.2  sour. 3  sweet. 4  bitter.5  umami.umans detect taste with taste receptor cells.

Raynaud's Syndrome May be the Cause of Your Fiery Fingertips. Another major cause of burning fingertips is Reynaud's Syndrome. This condition is brought about when the blood vessels that supply the hands and/or feet narrow. In individuals with Reynaud's, episodes of burning fingertips are exacerbated by exposure to cold.
Immediately run your burned finger(s) under cool (not cold) water. This will stop the actual burning sensation and will soothe the affected area. Fill a bowl with cool water and rest your hand in it for ongoing relief. Look for any skin damage. A mild burn is characterized by red skin and sometimes small blisters. You can treat a mild burn at home. However, if you have a severe burn (large blistering, charred skin, peeling skin), seek medical attention immediately. Apply an over-the-counter, topical burn ointment to your burn. Cover your hands/fingers with a non-sticky bandage. This will minimize the chance for infection.
