1
Q

What are the five different primary tastes?

A

Salty, sweet, bitter, sour, and umami

2
Q

What stimulates the taste buds for the umami taste?

A

Monosodium glutamate

3
Q

They form the capsule surrounding the taste receptor cells. These cells support and protect the receptor cells.

A

Supporting cells

4
Q

There are approximately 50 of these in each taste bud. It has a micro villi, called “taste hair”, protruding through a pore on the apical surface of the taste bud. These hairs are the receptor surface for taste stimuli.

A

Taste receptor cells

5
Q

These cells are found peripherally on the base of a taste bud. They develop into supporting cells and then into receptor cells which live about 10 days.

A

Basal cells

6
Q

These are small, spike-like projections found all over the tongue. They are the most abundant papillae, but lack taste. They roughen the tongue and aid in food manipulation.

A

Filiform papillae

7
Q

These papillae form parallel bands on the sides of the posterior two-thirds of the tongue. They have few taste buds.

A

Foliage papillae

8
Q

These papillae, as the name implies, are mushroom-shaped projections found all over the tongue, although they tend to be concentrated on the tip and sides. Each papillae has about five taste buds.

A

Fungiform papillae

9
Q

These are large circular papillae with a depression in the middle. There are about 12 of them arranged in a V-shaped row on the back of the tongue. They contain from 100 to 300 taste buds.

A

Vallate papillae

10
Q

What is the process for mapping taste buds?

A

Obtain the dropper bottles and place a single drop of fluid on the middle, lateral, tip, and base of the tongue, without touching the tongue. If the fluid is tasted, record the location of the taste. This is a blind test.

11
Q

Where on the tongue can you taste bitter?

A

Back of the tongue

12
Q

Where on the tongue can you taste sour?

A

Side/lateral

13
Q

Where on the tongue can you taste sweet?

A

Tip

14
Q

Where on the tongue can you taste salty?

A

Tip and lateral

15
Q

Where on the tongue can you taste umami?

A

All over
