Nervous and Endocrine Systems

The nervous system and endocrine system constitute the two main control systems of the body and as such, will respond first and foremost to any environmental changes, whether that be nutritional, electromagnetic or emotional.

In order to produce electrical nerve impulses, neurons must be triggered by a stimulus, which is anything inside or outside of the body that evokes a physical or psychological response. A neuron’s capacity to respond is known as the excitability. Impulses may be blocked or inhibited not only by poor diet, drugs, viruses or electrical shocks, but also by suddenly altering magnetic fields.

The main building blocks of the central nervous system are the Neurons, which contain a message transmitter called an Axon. This axon is usually stimulated by electrical activity generated within the neuron but it can also be stimulated by electrical and magnetic activity from outside its immediate environment. Changing magnetic fields can therefore alter the electrical activity of the nervous system by the same methods that cause an electrical motor or generator to operate.

The electrical impulses travel down the axon to the Synapses, shown in the diagram as the axon terminals, where it triggers a release of chemical messengers that in turn, trigger a response in a target cell. Elements such as magnesium and calcium, sodium and potassium, play a pivotal role and the electrical relationships at a cellular level between these pairs of elements is essential for optimum function of this body chemistry. 

Without going too deeply into this remarkable biochemical process, the balance between these chemicals, caused by the proper flow of electrical impulses, in turn caused by environmental changes, is so absolutely crucial for our physical, emotional and psychological well being.

The most subtle changes in our physical capabilities and moods from day to day may now be seen in a new light; the planetary orbits, the gravitational changes, the fluctuations in magnetic fields, all ultimately affecting the electrical and chemical activity in our bodies.

When we realise that the flow of these electrical impulses and chemical messengers are occurring throughout the body, any major stresses in the environment, such as an excess of positive ions just before a thunderstorm, may disrupt any part of the physical or emotional body. Each person has their own inherent weak points and will therefore respond to the stress according to the nature of their own weakest link.

The Sympathetic and Parasympathetic nerves are the two divisions of the autonomic nervous system, the Sympathetic nerves prepare the body for action by stimulation, for example by dilating the eye pupils and increasing the heart rate. The Parasympathetic nerves maintain, modify and restore energy, for example by slowing down the heart rate and constricting the eye pupils.

 

Endocrine System

The Endocrine System is so very closely tied in with the nervous system, it co-ordinates the body’s internal physiology, regulating its development and helping it adapt to nutritional and other environmental changes. The system is based on a number of glands, which secrete hormones to act on target tissues. Receptors within these sites then initiate a cascade of biochemical reactions to produce the specific response. Molecules secreted by neurones that excite or inhibit other neurones are called neurotransmitters. Hormones may be secreted by neurones or glands.

Endocrine cells secrete hormones into the blood stream, where they are carried to the target cells. These cells may be some distance from the secreting cell, such as the anterior pituitary hormone, which acts on the thyroid. Paracrine cells secrete local hormones that act on a nearby cell, such as glucagons and somatostatin that act on the adjacent cells that secrete insulin. Some agents, such as prostaglandins and insulin-like growth factors, can act on the originating cell, and in this case are described as exhibiting autocrine control. Neuroendocrine cells secrete molecules from the neural axon terminals in response to some neural signal, and a molecule such as adrenaline is released into the blood stream to travel to its target organ, such as the liver or adipose tissue. Cells that produce neurotransmitters secrete molecules from the axon terminals to activate adjacent neurone cells. The gastrointestinal tract has its own neural network and has been called the second brain.
