The hormone noradrenaline
The hormone noradrenaline is a natural, unprocessed substance that is secreted from nerve receptors and cells connected to the nervous system, and it has a very great effect on different areas of the human body, and most of the time it is referred to in its general name as the hormone of fight and flight, and its role in the extent of issuance Nerve signals as an adverse reaction to some situations in our life, not to mention the effects it emanates from immediately after a symptom occurs, such as an increase in the heart rate, an increase in blood pressure from time to time, and the processes of expansion and expansion in the lungs caused by the process of inhalation and exhalation, as well as excreted in the case of narrowing blood vessels Not important in the human body, as noradrenaline stimulates the sensory receptors spread throughout the body, as well as nerve impulses. [1]
The function of the hormone noradrenaline
If noradrenaline is injected into a vein as an antidote, it will restore the high or low blood pressure, especially in emergency cases, to its normal position, for example if a person's blood pressure drops in a way that indicates a risk to the organs of the body, especially the heart muscle and surrounding coronary arteries, Noradrenaline works to stimulate the so-called alpha receptors in the arteries and veins, as well as the beta receptors secreted from the heart , which leads to the activation of the heartbeat range and the natural contraction of the heart again by increasing the narrowing of the size of the blood vessels surrounding the heart, as it widens the arteries. And coronary vessels, in order to easily and easily contract the heart muscle. [2]
The hormone noradrenaline is derived from the hormone adrenaline , which is secreted by the marrow of the adrenal gland, and it has a general effect on other body systems, and this hormone is used by subcutaneous injection into a vein, as is the case with the hormone noradrenaline, but it works to increase the number of pulses heart due to lack of oxygen that the heart needs dynamically, and is also used in cases of treatment of heart and crisis chest diseases and congestion in the airways, it does play a vital role in the secretion of blood sugar, known as "sucrose" and breaks the fat cells that cause deficiencies in the growth of the muscles of the body Significant, and the excessive secretion of this hormone often occurs when intense emotions and fear occur, or in states of joy and other situations that we cannot afford to mention. [3]
The difference between adrenaline and norepinephrine
As for the difference between adrenaline and norepinephrine, it is not wide at all. The hormone adrenaline is a hormone that works on affecting and stressing the sympathetic receptors of a certain type called "alpha and beta" by an equal amount in both receptors. As for noradrenaline, it is a hormone that also affects the sympathetic receptors of the "alpha" type. "Only, but the effect of this hormone on beta receptors is weak and less effective than the previous one. [4]
