What Is Noradrenaline

Nervous system makes use of something that acts as a neurotransmitter for sending messages to different nerves and also to the tissues of muscle. This ‘something’ is a hormone called Noradrenaline. Stimulation of the nervous system makes adrenal glands’ inner portion, which is known as the medulla, to produce and spread noradrenaline. This hormone performs an action on certain parts of the brain that is associated with fear and responsiveness. It is important to control noradrenaline for those who are suffering from chronic depression and low blood pressure.

What could be the impact of increased noradrenaline level in the body?

  • Faster heart beat
  • Increased level of blood glucose
  • Increased metabolism
  • Increased blood pressure
  • Increased blood flow
  • Increased production of energy
  • Important noradrenaline facts

There are some vital facts that you should know about noradrenaline, which are

  • Noradrenaline has another name, which is norepinephrine
  • For the production of noradrenaline, it is important to synthesize dopamine
  • Tyrosine, which is an amino acid, is the forerunner to noradrenaline
  • Noradrenaline functions both as hormone and neurotransmitter and it is called neurohormone as well
  • Noradrenaline acts as adrenergic nervous system’s neurotransmitter
  • Noradrenaline helps a person to react to any hazardous situation

When Noradrenaline Is Prescribed

Patients who are suffering from chronic depression are often prescribed by the doctors to control noradrenaline level or use some medicines that can control the level of neurotransmitter. However, it is advisable that usage of such drugs must be strictly under the medical supervision of professional doctors. These drugs can give rise to side effects such as hiccups and headaches and even more serious impacts like high blood pressure and heart attack. Such drugs should not be prescribed to children.

How Noradrenaline Works

To know why noradrenaline is important, you should know how it works. There are two types of cell membrane receptors that get activated by noradrenaline, such as:

  • Smooth muscle (other than the ones present in the intestines) gets contracted by A receptors
  • B receptors give rise to the force and the rate of contractions of heart muscles. It also make the smooth muscles relax

Neurons release certain chemicals, known as neurotransmitters into the synapses, which is the space that is present between the nerves. When these chemicals release, they bind to the receptors of neurotransmitter for triggering a response in the subsequent adrenergic nerve of the same chain. Because of that, the adrenergic nerves act on the related neurotransmitters and noradrenaline. Entire human body constitutes of neurotransmitters and adrenergic neurons and mainly controls spontaneous reflexes that help the body to stay active by retaining proper breathing and heart rate.

Noradrenaline is one of the vital neurotransmitters in different portions of the central nervous system. It takes active participation in the regulation of blood pressure, mood and arousal. Therefore, it is important that proper care must be taken to maintain the right level of noradrenaline, so that various vital aspects of the body stay fine.
