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
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.
It is involved in the reception
of sensory impulses from the viscera.
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.
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
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.
It is associated with feelings
of rage and aggression
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.
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.
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
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
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.
