Lest We Forget - Wireless Anatomy Commentary

to relax, it becomes open to stimulation and if irritated will begin a second contraction before it has fully relaxed from the first. Hence, no number of repeated stimuli can induce tetanus in cardiac muscle; it must begin to relax before it becomes responsive to any outside influence.

Unlike inorganic substance, muscle increases instead of diminishing in size with use. This is true of other living matter also; e.g., brains, which grow with exercise. No one can explain this characteristic of muscle fibre [fiber], though it is inherent in the nature of the substance.

WIRELESS ANATOMY COMMENTARY

Were it not for this unique arrangement of the cardiac muscles' response, no one would live very long. Being situated in the center of the body, the etheric energy field is of a twelve-petalled circular arrangement, like a wheel and spokes made up of all four elements in their triune action as function. The wheel must turn over completely to get another start or push. The centrifugal action is predominant. The heart is the symbol of life in the temple of the body and the Queen's Chamber of the Grace of Life itself; it is the motherhood of all living things. Life flows and attracts as it acts. The positive pole of the heart is in the optic thalamus of the brain where the soul current of the individual life is maintained and radiated to the heart. The cessation of the life impulse is here bound up with the soul's residence in the life stream. The dweller within the body can withdraw its energy thru [through] the optic center of light and leave thru [through] the crown of the head as an emanation of energy with radiating colors. Liberated energy has color and often sounds like a crackling fire; but our material concept does not extend to the finer energies of man or his soul as the primal essence of all energy. The spasm which the heart is subject to are usually coronary insufficiency - not enough blood to the heart muscle with which to function; or a clot or thrombosis which obstructs the circulation. Gas in the stomach and under the diaphragm often causes pressure symptoms that are mistaken for heart spasms or coronary attacks.

The Medulla

The medulla is connected with the control of respiratory and circulatory organs. It lies beneath the cerebellum and its lower end is continuous with the spinal cord from which it is not distinctly separate. Large bundles of fibres [fibers], crura cerebri [cerebral crura], extend from its upper end into the cerebrum. The medulla contains respiratory and vasomotor centers. In the medulla is also the cardio-inhibitor [cardioinhibitor] center from which messages go over the vagus nerves [pneumogastric nerves, CN X] to check the beating of the heart. Although the above are the most important, there are other centers located in the medulla; but, in general, we may say that the medulla is the seat of all involuntary activities.
