Noradrenaline (Noradrenaline), Norepinephrine (Pogepinephrine)

Noradrenaline, Norepinephrine - a hormone closely related to adrenaline and having a similar effect; secreted by the adrenal medulla and released by sympathetic nerve endings as a neurotransmitter. This hormone causes small blood vessels to constrict, causing blood pressure to increase in the body; thanks to its action, blood flow through the coronary arteries increases, the heart rate accelerates and increases; The frequency and depth of respiratory movements increases, ventilation of the lungs increases, the bronchi expand, and the smooth muscles of the intestines relax and motility weakens. In addition, glycogenolysis and lipolysis are enhanced.

Noradrenaline, also known as norepinephrine, is a hormone that is closely related to and has similar effects to adrenaline. It is secreted by the adrenal medulla and released by sympathetic nerve endings as a neurotransmitter.

One of the main effects of norepinephrine is to cause small blood vessels to constrict, which increases blood pressure in the body. It also increases blood flow through the coronary arteries and speeds up and increases the heart rate, which can be beneficial in cases of heart failure. In addition, the frequency and depth of respiratory movements increases, ventilation of the lungs increases, the bronchi expand, and the smooth muscles of the intestines relax and motility weakens.

Norepinephrine also enhances the processes of glycogenolysis and lipolysis, which can be useful during intense physical activity.

It is important to note that the level of norepinephrine in the blood can vary depending on various factors. For example, stress and physical activity can lead to an increase in its secretion, while meditation and other relaxation techniques can reduce its level.

In addition, in medical practice, norepinephrine is used as a drug to maintain blood pressure in cases of shock and serious circulatory disorders.

Norma is a concept that reflects the healthy, real state of a person. A structure (state) of an organism or organ should be considered normal in which its function is not impaired. In medicine, the concept of normal is used to assess various indicators of the body, including the level of norepinephrine in the blood. However, it should be understood that the norm may vary depending on age, gender and other factors. Therefore, to correctly interpret the analysis result, it is necessary to take into account all these factors.

Norepinephrine (or norepinephrine) is one of the biological amines, which, together with its structural analogue - adrenaline, belongs to the catecholamines. Norepinephrine has also been named a neurotransmitter.

This biologically active amine is a product of chemical synthesis in nerve cells like the central nervous system. It is secreted by noradrenergic nerve terminals located in the central nervous system, namely the so-called adrenal medulla. Norepinephrine then has to leave the brain and then travel to other areas of the CNS to ultimately reach peripheral receptors.

Biosynthesis. If necessary, more norepinephrine is produced than is usually synthesized from dopamine. Why do norepinephrines enter tissues? For two main reasons. This consists of either stimulation of central sympathetic nerve endings or local
