Norepinephrine, which is also known as noradrenalin or levarterenol, is a secretion by the human brain that is being excreted by the adrenal gland. It acts as a neurotransmitter as well as the stress hormone in your body. It is present in the medulla of adrenal gland in central nervous system and sometimes in sympathetic nervous system as well. It is also being used in hospitals commercially as a treatment to dangerously low blood pressures of patients. Norepinephrine Information As a neurotransmitter, the function of norepinephrine is to transmit nerve impulses from one neuron to another and treating unhappiness in turn. While as a stress hormone, it produces sudden energy and power in the body during a stressful situation so that your body will become able to give fight and flight responses to the stress. As it is secreted by the adrenal gland, it works alongside with adrenaline to produce energy in the body. On the other hand, its structure is also similar to that of adrenaline. Functions of Norepinephrine The main functions of norepinephrine are: •    To produce energy in the body during stress, •    To increase blood pressure, •    Increase blood flow in blood vessels providing it to the body muscles appropriately, •    Stimulates the amount of sugar in blood by producing glucose in  the liver, •    Necessary element to use while performing CPR •    Activating central nervous system and autonomic system to give response to the stress by making them ready for the fight and flight responses ...

Norepinephrine is a neurotransmitter as well as the stress hormone of our body. This chemical, which is also known as Noradrenalin or Levarterenol, is produced within the human brain. Norepinephrine can be found in central nervous system and sympathetic nervous system. It is found in the medulla of adrenaline, which is present in the central nervous system. It directly affects the human body and mind if its amount becomes unbalanced. However, this neurotransmitter is produced or secreted by the adrenal glands and it works in conjunction of adrenaline, as a stress hormone to produce energy in the body. In this way, it activates the central nervous system, mental disorder relief and sympathetic nervous system to perform fight and flight responses against stress. Its structure is basically same as the structure of adrenaline. Functions of Norepinephrine Norepinephrine is used for alarm reactions as stress hormones in stressful situations. However, measuring Norepinephrine is done through blood and urine test as they are found in the blood and urine as breakdown products. To measure the Norepinephrine levels in your body, you have to give the specimen of your blood or urine for tests. However, the urine samples within 24-hours are preferable, as they are not affected by pulse variations. Generally, in a healthy person, a little amount of neurotransmitter is found. However, if the Norepinephrine levels exceed somehow then the person might suffer from headache, sweating, high breathing rate, high blood pressure, melancholia definition, anxiety and depression. Therefore, measuring Norepinephrine is necessary to ...
