Pheochromocyte

Pheochromocytes are cells that produce the hormone adrenaline in the human body. They are found in the adrenal glands and their function is to respond to stress and other factors that cause adrenaline levels to increase in the blood.

Adrenaline is a hormone that is responsible for increasing heart rate, increasing blood pressure, dilating blood vessels and accelerating metabolism. It is also involved in regulating certain body functions such as respiration and digestion.

Pheochromocytes respond to stimulation by certain hormones such as norepinephrine, as well as to various stressors such as fear, anxiety, pain, etc. When the level of adrenaline in the blood increases, pheochromocytes begin to produce more adrenaline, which leads to an increase in the level of this hormone in the blood and corresponding changes in the body.

However, excess production of adrenaline can lead to various health problems such as increased blood pressure, increased heart rate, insomnia, anxiety, etc. Therefore, it is important to control the level of adrenaline in the body and avoid stressful situations if possible.

In general, pheochromocytes play an important role in regulating the functioning of the body and maintaining its homeostasis. However, their excess production can lead to serious health problems.

Pheochromocytes are special cells of the adrenal cortex responsible for the production of the hormone adrenaline. These hormones are extremely important for a person's response to stress - thanks to them, a person can gather himself to take decisive action. Therefore, one of the popular names for pheochromocytes is “hormones of heroism.” And these cells also regulate the circulatory system and heat exchange. If the thymus (not only among the ancient Greeks, but also among most people) is the organ that controls immunity, then the adrenal glands are the thermoregulation system. That is, in fact, these cells transfer to the kidneys the functions of their former reticular substance, which is responsible for the body temperature control system, which is now under the control of the hypothalamus. Interestingly, sometimes during stress the adrenal glands begin to produce norepinephrine rather than adrenaline.
