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.
