Functions of Norepinephrine
Norepinephrine is also known by the name noradrenaline. It can be released in the central nervous system by the neurons, but often times it is the medulla, the adrenal gland’s core portion, which is producing the noradrenaline when needed by the body. Noradrenaline is considered as a neurotransmitter and also as a hormone.
Norepinephrine has a wide set of functions in the body: in the liver, cortisol, in the nervous system, in the vascular system, and other related functions.
Norepinephrine is produced in the body only in a limited time and only in special cases when it is really needed. Cortisol, on the other hand, works in reverse with norepinephrine. Once the cortisol is released by the adrenal cortex, it limits the production of norepinephrine in the adrenal medulla. This process is very important, since body’s release of norepinephrine for a long period causes side effects such as temporary stopping some minor processes inside the body such as digestion.
It affects the liver by modifying its speed in glucose production, which leads to a boost in the body’s energy production. This usually happens in sudden stressful situations.
In the nervous system, norepinephrine helps upon the activation of the body’s fight-or-flight situation by boosting the body with an increased attention and reaction time. Norepinephrine is one of the main components that triggers the sympathetic and central nervous system to become hyperactive in times of sudden stressful situations.
Noradrenaline is also present in several vascular system activities. In situations like increase in heart rate, dilation of blood vessels, and increased blood pressure, norepinephrine is always present.
The functions of norepinephrine does not only applies inside the body, when excreted and processed it also helps in a wide set of medicinal uses. As a component of different prescription medications, it is contained in different medicines such as hypotension medications and antidepressant drugs.
