Stress  - body respons

I believe most of us know how our body reacts to stress. However in this blog I write about this- just as a remainder. I am not going into details here:)

Reaction to stress is an example of cooperation between the sympathetic and parasympathetic nervous system.

Any kind of fear, tension and stressful situation acts through the brain on hypothalamus,

which releases a hormone that stimulates the pituitary gland to secrete adrenocorticotropic hormone ACTH and this one stimulates adrenal glands to produce cortisol.

Cortisol is a hormone which regulates the metabolism of organic compounds.

Through the sympathetic part of the autonomic nervous system adrenal medulla is stimulated and adrenaline is released. Adrenaline is a hormone which:

• increases blood pressure,
• increases the level of glucose in the blood,
• accelerates metabolism of fats,
• causes vasodilatation in skeletal muscle and constriction in the skin and abdominal cavities
• bronchodilation,
• acceleration of breath,
• expansion of the pupils.

Our body is prepared for short-term reaction to stress. However we have to remember that

chronic stress is a threat to health and this is going to be a topic of my next blog.

Two more blogs about stress and I am going to change a subject otherwise you will never read my blogs :):):):):)
