Paraganglii

Paraganglia are clusters of neuroendocrine cells located in various parts of the human body. They play an important role in regulating blood pressure, metabolism and other physiological processes.

Paraganglia are small structures that can be found in various organs and tissues. The most common locations of paraganglia are the kidneys, adrenal glands, thyroid gland, brain and heart.

The paraganglia contain cells called chromaffinocytes. These cells have the ability to secrete hormones such as adrenaline and norepinephrine. Epinephrine increases the heart rate, dilates blood vessels and increases blood pressure, while norepinephrine decreases the heart rate and constricts blood vessels.

In addition, paraganglia also contain neurons that are involved in regulating various body functions. For example, paraganglia in the adrenal glands secrete hormones that help control blood sugar and maintain normal blood pressure.

However, paraganglia not only regulate physiological processes, but also play an important role in the development of various diseases. For example, with thyroid disease or diabetes, the level of hormones in the paraganglia may change, which can lead to disruption of body functions.

Thus, paraganglia play an important role in maintaining the normal functioning of the body and regulating physiological processes, but their dysfunction can lead to various diseases.

Paraganglia are compact clusters of neurons, neurilemmal ganglion cells and their processes that do not have their own glia. Paraganglial bodies are located in various organs and tissues. Adrenal paraganglioma is especially common. A couple were also spotted
