What are the 5 tastes?

Tasting 

Tongue can taste: 

sweet, salty, sour, bitter, umami

With help of nose you can taste 

the difference between:

• chocolate
• bread
• apple
• milk
• etc.

Tongue can taste: sweet, salty, sour, bitter, umami

Tongue can also notice textures of food

1

smells of food in the mouth travel to the nasal cavity while eating

2

olfactory cells in the nasal cavity also 'taste' the food.

Helping you recognize more flavours than the basic 5.

3

Umami, also called the fifth flavour.

It mainly enhances how you experience the other 4 flavours. 

The tongue

Sweet, salt, etc. can be experienced everywhere on your tongue! 

Not in specific places, as many pictures (like this one) try to make you believe

tongue

taste buds in the tongue

mucus gland

nerve

nerve

sensory cell

taste bud

groove

 a taste bud

Produces mucus, keeping you tongue moist.

This also helps you taste better.

A dry tongue has much difficulty tasting.

Taste buds contain sensory receptors that turn 'taste' stimuli into impulse which can be sent to your brain.
