Etymologies of OSS-É-O-PRAXIE®
And reminders of the fundamentals

THE BONE (S) PREFIX… for Bone and TISSUE

The prefix OSS is used in the idea of talking about all the tissues of the body i.e. connective tissue with all its variants, dense tissues such as bones, cartilages, tendons, cornea and more tissues flexible such as organic and supporting tissues (up to aponeuroses, membranes, fascia), as well as epithelial tissue, muscle tissue and nervous tissue.
Connective tissue is the most extensive. It makes up all of the organs, including the skin, muscles, bones, nerves and nervous system, blood vessels, outer membranes that surround the brain and spinal cord. It is also placed between other tissues of the body. It has 3 essential constituents: fibers (elastic and collagenic), ground substance and cells (fibroblasts, adipocytes, macrophages, mast cells, leukocytes). Constituting more than 80% of the body, it can be differentiated into several families, some of which are:
The supporting connective tissue is called mesenchymal. It is involved in the maintenance of structures such as bones, organs, muscles and veins.
Dense connective tissue , deep dermis, cartilages, tendons.
Bone tissue which is made up of hard ground substance impregnated with calcium salts. Itself composed of 3 categories, the reticular (immature bone), the lamellar (90% of the body's bone tissue, resistant), the spongy (in short bones, flats and epiphyses of long bones).

​

Epithelial tissue. It is not vascularized, but it is nourished by the contiguity of the connective tissue, thanks to the basal lamina. It has a coating function and a glandular function.
These are the epidermis, gastric epithelium, intestinal tract, respiratory tract, bladder ...

​

Muscle tissue.
It is classified into 3 categories, striated skeletal muscle, striated cardiac muscle and smooth muscle.

​

Nerve tissue .
It is an extremely complex fabric. Its composition is made of neurons and glial cells (neuroglia), myelinated nerve fibers (white matter), amyelin nerve fibers (gray matter).
Let us quote some cells of the nervous tissue: 
Astrocytes, whose extensions go to meet neurons to support them and meet capillaries to form the blood-brain barrier. These astrocytes support neurons and maintain nerve coherence.
Oligodendrocytes whose extensions surround axons to myelinate them in order to increase the transmission of nerve impulses.
The part of the nervous system that concerns us the most is the autonomic nervous system also known as the visceral or vegetative nervous system. It manages functions not subject to voluntary control, smooth muscles (digestion, vessels ...) heart muscles, exocrine glands (digestion, sweating) and certain endocrine glands.
It is made up of cranial sensory ganglia (afferent pathways) for sensory information (such as blood oxygen content, blood pressure, intestines dilation) that goes to the core of the solitary tract located in the central nervous system.

From there start the efferent pathways made up of 2 antagonistic nervous systems, the orthosympathetic (ergotropic, linked to stress) and the parasympathetic (trophotropic, linked mainly to rest). The role of these efferent pathways is to adapt physiological modifications (such as the release of digestive juices, dilation of the bronchi, etc.)
This visceral autonomic nervous system depends on the central nervous system, which is regulated by the hypothalamus, the brainstem and the limbic system receiving the influence of emotions and the somatic nervous system with its afferents from the sense organs, exteroceptors and proprioceptors.
The axons of sympathetic and parasympathetic neurons form plexuses located in the thorax, abdomen and pelvis, controlling respiratory, digestive, cardiovascular functions and acting on visceral secretions, visceral motricity (peristalsis), on the exocrine and endocrine glands and on vasomotricity.
 

THE PREFIX "É" ...

For electric, referring to the nervous system.

Neurological pathways, including those of the autonomic, sympathetic and parasympathetic system, carry electrical information to the organ concerned. The play of ionic polarity called "action potential" is an excessively rapid process in which channels open through the cell membrane, allowing calcium and potassium ions to pass. It is a process of polarization and depolarization of the membrane, all along the axon (nerve) which promotes nerve impulses. This is how nerves conduct electricity to organs, allowing contractility or inhibition.

Let us now assume that compression or discomfort occurs in its path. This will create a conduction dysfunction, much like hitting the wire of an electrical device with a hammer. There would then be a malfunction of the device. It is the same phenomenon that can be attributed to the organs. In this way, following certain external events (trauma by accidents, sports trauma), prolonged bad attitudes (postures at work, on the sofa, at the table, at the office, etc.) or various incidents (false movements, injuries). emotional, etc.), may have physical, chemical or biological effects on the supporting tissues of the nerve sheaths and have consequences on the nerve pathways, affecting their functionality.

THE PREFIX O ...

Phonetics of “WATER” - representing all that is fluid, fluid such as arterial and venous vascular system and lymphatic system, lymph and interstitial fluid.

The vascular system carries blood throughout the body. It is made up of arteries, arterioles and capillaries (variable diameters from the heart to the organ) and its role is to transport oxygen and nutrients to the organs.
Blood returns from the organs to the heart through the venous system, made up of venules and veins, carrying carbon dioxide (C02) to the lungs to be replenished with oxygen.

The constitution of the arterial walls is made of:
•   The innermost intima (a loose connective tissue endothelium),
•   The media (smooth muscle cells composed of collagen and elastin),
•   The adventitia (the outermost, made of collagen, elastin and adipocytes).
They are innervated by the sympathetic system which gives it its contractility.


The constitution of the venous walls:
Identical to those of the arteries, but some are provided with valves (in the lower limbs) to allow the venous return to the heart.
Venous compliance is 24 times that of arteries.

​

You will thus understand the role of osseopraxia on the vascular system, since the latter is made up of connective tissue and the important role of the autonomic (sympathetic) system in the contractility of the walls (arteries).
Tissue restoration, endothelial and collagen, by the digital vector technique , will act on the one hand on the tone of the vascular walls (those which may be accessible) and the release of peripheral tissue constraints, but also on the electrical role of the sympathetic system in contraction of arteries, arterioles and capillaries. In this way, vascular dynamics, the supply of oxygen and nutrients to the organs, but also the venous return to the heart will be improved.

The lymphatic system is made up of lymph, interstitial fluid, lymph vessels, lymph nodes, and lymphoid tissue.
Locations of lymphatic constituents: Some parts of the body are richly composed of white blood cells (basic elements of the lymph). They are made up of lymphoid tissue with its lymph nodes, MALTs (lymphoid tissue stuck to the mucous membranes), the spleen and the thymus. The bone marrow rich in white blood cells is apart. The latter and the thymus make lymphocytes, necessary for immune defense.
The role of the lymphatic system is to detoxify organs (transport waste from cellular activities), carry nutrients, transport white blood cells for immune defense and circulate hormones.
Lymph is produced by transudation of blood plasma at the level of blood capillaries. It plays a major role in the immune system (white blood cells), provides the blood with fats and nutrients absorbed from the small intestine by the chylifera of each intestinal villi.
Interstitial fluid (made up of lymph) fills the spaces between cells and blood capillaries. It has a role of drainage and purification and returns to the blood through the lymphatic vessels.
The lymphatic vessels begin in the body tissues to join the lymph nodes, take large axes such as the Pecquet cistern or the chyle cistern between the pillars of the diaphragm and retro aortic at the origin of the thoracic duct opposite the second lumbar and terminate in the left subclavian vein. The right lymphatic duct will drain the right arm, the right thorax, the neck and the head, to drain into the right subclavian. In the end, the thoracic duct and the lymphatic duct will flow into the venous circulation. 
The circulation of the lymph is done by the respiration, the contraction of the muscles and the movement, but also by the contraction of the smooth fibers of the walls of the vessels, hence the importance of a good sympathetic neuro-vegetative system.
One of the lymph circulation disorders is edema, but also a decrease in immune defense, the nutritional capacity of cells, detoxification of the body and its consequences on health. 
The movements of the body, the physical activity and the freedom of the autonomous ways allow a better circulation of the lymph.
The intervention of the osteopraxis will be done on the connective tissue, certain articular crossroads, the places of lymph node concentration, the anterior sacral and vertebral surfaces as well as on the interstitial tissue and the lymph of the places concerned, thus generating a fundamental response on the immune system and cellular activity. 
By its digital vector action, it will make it possible to release the constraints exerted on the lymphatic pathways, whether of ligament, aponeurotic or fascial origins, in order to restore good lymph circulation, locally on the one hand, but also on the main return routes.

As far as we are concerned, this brief explanation which has just been given to you is essential so that you understand that all these bodily tissues are intimately linked, that they form a tissue continuity and therefore a functional whole. This is what allows us to understand the capital importance of osseopraxy and its subtle techniques, including the "digital vector technique", by its ability to act on the suffering tissue fibers, after having detected the cellular limitations, their loss of rebound, rhythmicity and resilience.
Respect for these fundamental characteristics is essential for maintaining correct physiological functions. If the tissue continuity is broken or obstructed, the information transmitted will be erroneous or deficient, even deleterious. This is the first step towards illness. 
The role of osseopraxy is to restore the neuro-vegetative balance by releasing the tissue constraints from which it could be affected.

PRAXIA:

Greek etymology meaning the adaptation of movement to a specific purpose. In our case, it is essentially a digital vector technique allowing to have a tissue response in a precise direction, previously diagnosed by an abolition of its reactivity and its rebound capacity. His rhythm, his capacity for resilience are affected. The digital vector technique makes it possible to recover these deleterious physicochemical and biological capacities and to free restricted mobility.
