The taste analyzer consists of 3 departments.

The peripheral part in the form of taste buds.

Large - mouth, chewing food.

Most of the taste buds are located on the tongue, in the taste buds.

Mushroom-shaped papillae are located on the tip of the tongue.

Microphotography of papillae.

Electron microscopy gives a detailed picture of the structure.

Leaf papillae are located on the side of the tongue.

The grooved papillae are located at the root of the tongue.

Taste buds are visible in the multilayer epithelium.

Taste substances penetrate into the kidneys through the pores.

The composition of the taste bud.

Taste cells, support cells and basal cells.

Nerve endings forming afferent and efferent synapses are suitable for each taste cell.

The tops of the cells have villi that face the taste canal and are covered with glycocalex.

A person is put lump sugar in his mouth.

The sugar molecule hits the surface of the mushroom papilla.

A cartoon explaining the principle of the taste bud.

An experiment that allows you to get acquainted with the taste reception.

The frog's tongue.

An irritant is fed into the tongue of an immobilized frog, exactly into the cell of the taste bud.

This leads to the output of the mediator.

With the help of an electron microscope, it was possible to fix the bubbles of the mediator.

A cartoon showing the transformation of a mediator into nerve impulses.

The pharyngeal nerve is isolated from the neurovascular bundle of the frog and superimposed on the electrodes.

When exposed to an irritant, the electrical activity of the nerve, which is part of the conductor department of the taste analyzer, is recorded.

A cartoon explaining the creation of a holistic image of the taste sensation.

An experiment to determine the part of the brain responsible for taste sensations.

An experiment to determine the concentration of a substance at which a taste sensation occurs.

As a result of the experiment, it was determined that the front part of the tongue is most sensitive to sweet.

To bitter - the root of the tongue.

The sides of the tongue perceive sour and salty better.

With prolonged exposure, the phenomenon of adaptation occurs.

Not only sensitivity decreases, but also the number of functioning receptors.

The experiment shows that the taste buds do not work constantly, but are periodically turned on and it depends on the state of the body.

Experiment with taste buds in space.

Eating reduces the number of taste buds, while activating the work of the pancreas and liver.

The blood sugar content increases.

This reduces the taste perception and the feeling of hunger disappears.

The taste analyzer does not act in isolation.

In addition to olfactory taste receptors, temperature and tactile ones were connected.

Sharp taste is associated with pain sensitivity.

Food evokes emotions.

The emotional state affects the taste sensations.

The students' exam.

Stress affects all sensations, including taste, and the pulse quickens.

Tasters have a highly developed taste perception.
