Norepinephrine's effects on the brain involve the areas that regulate attention, sleep, learning and emotions.

NOREPINEPHRINE AND ITS IMPORTANCE........

THE FUNCTION of norepinephrine in the

body is a body’s “ flight or fight” system is

designed for the body to become aware of

threats or a stressful situation. Norepinephrine

helps the process by increasing blood sugar

levels and opening up the airways, and

converting bodily fats to acids. This Flight or

fight system also triggers the blood pressure

and heart rate in increase. Norepinephrine

coordinates the communication that happen

within the sympathetic nervous system.

NOREPINEPHRINE is an excitatory

neurotransmitter that is responsible for

stimulatory processes in the body.  This

neurotransmitter can cause ANXIETY at

elevated excretion levels.  Low levels of

norepinephrine are caused low energy,

decreased focus ability and sleep cycle

problems.

NOREPINEPHRINE affects the regulation

of body functions such as; heart rate,blood

pressure and sugar levels. Norepinephrine is

secreted by the adrenal medulla glands, and it

is produced by nerve endings found in the

sympathetic nervous systems. When

norepinephrine is released and stimulates the

emotional and cognitive centers of the brain

Norepinephrine also affects the brain with

regulating attention, sleep, learning and

emotions.

AN IMBALANCE of norepinephrine can

cause a number of psychological disorders

such as; depression and bi-polar. Low levels of

norepinephrine

NEUROTRANSMITTER: IS A CHEMICAL THAT IS RELEASED FROM A NERVE CELL WHICH THEN TRANSMITS AN IMPULSE FROM A NERVE CELL TO ANOTHER NERVE TO ANOTHER NERVE, MUSCLE , ORGAN, OR OTHER TISSUE. A NEUROTRANSMITTER IS A MESSENGER OF INFORMATION FORM ONE CELL TO ANOTHER.

Norepinephrine is a main component to the fight or flight response. Norepinephrine is responsible for helping our bodies recognize and respond to stressful situations.

SOME PEOPLE who are depressed have

shown activity of hyperactivity within the

neurons that produce norepinephrine. Since

norepinephrine is responsible for helping our

bodies recognize and respond to stressful

situations, symptoms of depression are likely to

occur with low levels of norepinephrine.

NOREPINEPHRINE’S role in the brain and

the body is to stimulant and requires a certain

level of this chemical to be present get a normal

emotional and mental function. When low levels

of norepinephrine are present, depression may

be a result. A person may feel less alert and

have low energy levels. There are a number of

different medications used to help treat

depression and they are designed to target

norepinephrine and dopamine levels to bring the

chemical balance within the brain.

HIGH LEVELS of

norepinephrine can a forms a continuous feeling

of  hyperarousal. The feeling of being hyper can

cause one person to feel a lot of anxiety, to have

the jittery or be grouchy. Some physical effects

can include muscle tension, increased heart rate

and jumpiness.  When too much norepinephrine

a body is consistence  anxiety disorders can

develop.  Panic attacks are very common when

there is a large amount of the chemical in one’s

body. Panic attacks symptoms are sweating,

hyperventilating rapid heart beats are all a result

of this chemical effects on the brains body

processes.

SOME MEDICATIONS that could interact

with norepinephrine would be, most blood

pressure medications, an MAO inhibitor and

some antidepressants.
