my gp is doing test for salt taste what test will he carry out?

Answer 1

Each half of the tongue is tested seperately. Cotton swab drenched in salt solution will be kept on the tip , sides,in front and behind and you will be requested to indicate your salt taste with a finger sign ie without talking.This test is done to test the integrity of glossopharangeal nerve
Thousands of tiny taste buds cover most of the tongue's surface. Food placed in the mouth stimulates taste receptors in the taste buds. Taste receptors have cilia that detect tastes. Food molecules stimulate the cilia, triggering a nerve impulse in nearby nerve fibers, which are connected to the cranial nerves of taste (the facial and glossopharyngeal nerves). The impulse travels along these cranial nerves to the brain, which interprets the impulse as a distinct taste. Taste buds can detect sweetness, saltiness, sourness, and bitterness. Combinations of the four basic tastes produce a wide spectrum of tastes.
Tip of the tongue recognises salt taste. Sides rcognise sweet taste.
A substance not soluble in water has no taste

Answer 2

I'm not sure but if its a taste test then it will be either something to smell or something to put on your tongue (probably something edible)
