How to draw and label the tongue

Tongue is made up of muscles. It contains about ten thousand taste buds. The taste buds are located in wall of the papillae.Like smell, taste is also a sense based on identifying chemicals in food and the texture. The sense of taste and smell have a close and cooperative working relationship. The sense of taste 'Gustation' involves qualities of Sweet, sour, bitter and salty. Umami is the savory flavor found in protein rich foods such as meat, seafood and cheese.It is associated with Monosodium glutamate(MSG) also called huching, often used in Asian cuisine.  Now, let's  draw.

1. Draw out line of tongue as shown.

2. Draw line in the middle  and above as shown.

3. Draw Papillae of different forms on tongue as shown.

4.Label the parts neatly.

Cont:-The taste receptors cells, located in the taste buds on the top and side of the tongue, sample flavours from food and drink as they come into contact with surface of tongue. These taste receptors cluster in small mucous membrane projections called 'Papillae'. Each is sensitive to molecules of a particular type.The flake like structures on tongue are called Filiform papillae, the roundish ones at the back of the tongue are vallate papillae, the bump like structures on sides of tongue are Foliate papillae. Taste buds are present in all these papillae except the Filiform papillae. Each taste bud has a cavity with a pore called taste pore. The epithelial cells, surrounding the taste buds form the taste cells or the receptors. The receptors cells are situated in the cavity. Each receptor connects to the nerve fibre. All the nerve fibres connect to main nerves that carry impulses to the brain.
