Stress Causes

Fear, Stress Causes and Physiology


The Endocrine System


The endocrine system consists of the pituitary, the pineal gland, parathyroid glands, thyroid glands, thymus glands, adrenal glands, pancreas, ovaries, testes, and hypothalamus.


I am going to tell you where they hypothalamus gland is.  How many of you have ever struggled with tension?  When you have tension, do you ever have the back of your head hurt from tension?  You remember which hand goes where? 


The hypothalamus gland is located in the third ventricle.  This is where it starts to hurt.  With tension, stress, and pressure, you start to rub your neck don’t you?  I check people for tension just by checking their neck out.  That’s the effect of stress and anxiety.


They hypothalamus gland is the “brain” of the endocrine system, and it sends out various types of chemical messengers to the endocrine system.  There are many types of hormones involved in stress and anxiety.  The hypothalamus gland is the facilitator for many things.  We’ll go over that with you.


Hormones travel to receptor sites in muscles or tissues where an action is produced.  A reaction is a direct result of a combination of hormones being secreted by the hypothalamus and the central nervous system being activated by fear, and anxiety and stress. 


When you are subjected to your stressor, when you’re exposed to the thing you think you are allergic to, sometimes people react.  Sometimes they react and don’t even know they are around it, and that seems to reinforce their belief in their sickness.


Fear is not just an emotion.  The Bible calls fear at this level an evil spirit.  Once the spirit of fear is out of their life, there is a release and healing.  Now I don’t know if that’s part of your theology.  If you can get healed another way, then God bless you!  All I know is that when the spirit of fear is gone, people are well.  Fear of evil is a national tragedy in the Christian church. 


Principles of anatomy and Physiology by Gerard J. Tortora and Nicholas P. Anagnostakos, describes thy Hypothalamus Gland attributes.


1.    It controls and integrates the autonomic nervous system, which stimulants smooth muscle, regulates the rate of contraction of cardiac muscles, and controls the secretions of many glands.


2.    It is involved in the reception of sensory impulses from the viscera.


3.    It is the principal intermediary between the nervous system and endocrine system – the two major control systems of the body.  The hypothalamus lies just above the pituitary, the main endocrine gland.  When the hypothalamus detects certain changes in the body, it releases chemicals called regulating factors that stimulate or inhibit the anterior pituitary gland.  The anterior pituitary then releases or holds back hormones that regulate carbohydrates, fats, proteins, certain ions, and sexual functions.


4.    It is the center for the mind-over-body phenomenon.  When the cerebral cortex interprets strong emotions, it often sends impulses along tracts that connect the cortex with the hypothalamus.  The hypothalamus then directs impulses via the autonomic nervous system and also releases chemicals that stimulate the anterior pituitary gland.  The result can be a wide range of changes in body activities.  For instance, when you panic, impulses leave the hypothalamus to stimulate your hear to beat faster.  Likewise, continued psychological stress can produce long-term abnormalities in body function that result in serious illness.  These are so-called psychosomatic disorders.  Psychosomatic disorders are real.


Let me say this to you:  the hypothalamus gland is the facilitator and the originator of the following life circumstances:  All expressions of


·        Fear

·        Anxiety

·        Stress

·        Tension

·        Panic

·        Panic attacks

·        Phobia

·        Rage

·        Anger, and

·        Aggression.


These are all released and facilitated by this one gland.  It only responds to you emotionally and spiritually.  The hypothalamus is called the “brain of the endocrine system,” but it is not a brain.  It is a gland.  It is a responder to though.  It is a responder to the environment of your life.  It will only produce what is happening deep within the recesses of your soul and your spirit.


5.    It is associated with feelings of rage and aggression


6.    It controls normal body temperature.  Certain cells of the hypothalamus serve as a thermostat – a mechanism sensitive to changes in temperature.  If blood flowing through the hypothalamus is above normal temperature, the hypothalamus directs impulses along the autonomic nervous system to stimulate activities that promote heat loss.  Heat can be lost through relaxation of the smooth muscle in the blood vessels and by sweating.  Conversely, if the temperature of the blood is below normal, the hypothalamus generates impulses that promote heat retention.  Heat can be retained through the contraction of cutaneous blood vessels, cessation of sweating, and shivering.


7.    It regulates food intake through two centers.  The feeding center is stimulated by hunger sensations from an empty stomach.  When sufficient food has been ingested, the satiety center is stimulated and sends out impulses that inhibit the feeding center.


8.    It contains a thirst center.  Certain cells in the hypothalamus are stimulated when the extra cellular fluid volume is reduced.  The stimulated cells produce the sensation of thirst in the hypothalamus.


9.    It is one of the centers that maintain the waking state and sleep patterns.


The limbic system is the connection between your cerebrum where your brain is, down through to your hypothalamus.  It is the connection between psyche (though) and physio (the body).  It is the connection between soul and body.  Everything that concerns thought travels right down that connection.  Good thoughts and bad thoughts.  All of these parts are connected:  the limbic lobe, the hippocampus, the amygdaloid, the hypothalamus, and the anterior nucleus of the thalamus.  Everything is connected in order to process thought and give it expression in the physiological part of our lives.  Just as fear can put you into fight or flight, peace can bring you into peace.


Jesus said this in John 14:27.  “Peace I leave you, my peace I give unto you:  not as the world giveth, give I unto you.  Let not your heart be troubled, neither let it be afraid.


The Bible says ---perfect peace belongs to those whose minds are fixed or stayed on the LORD.


Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusts in thee.  Isaiah 26:3


The antidote to fear is fellowship with God.  “for God has not give us the spirit of fear; but of power, and of love, and of a sound mind.  2 Timothy 1:7


Power represents the Holy Spirit, love represents the love of the Father, and a sound mind represents the Word of god, Jesus.  If you are filled with the fellowship of the love of God the Father and of the Son and of the Holy Spirit, fear does not have a shot at you. 


If you are listening to fear, you are not listening to God.


The limbic system functions in the emotional aspects of behavior related to survival.  When you do not feel loved, when you have been victimized, when you don’t feel secure, you fight for survival. 


When you have been rejected by a parent or by anyone else, when you do not feel loved, when you feel violated, you are always looking over your shoulder for when the next hit is going to come.  You are in fight or flight.


The limbic system also functions in memory.  Although behavior is a function of the entire nervous system, the limbic system controls most of its involuntary aspects.  One of the things about illnesses is that it’s often invisible.  It always involves everything deep within the person, and we usually do not understand by our intellectual processes what’s gong on.  That’s why it is so difficult to see it. 


I had a lot of work ahead of me.  Now looking back it was simple, not always easy.  The results are peace and health.
