Muscles
_I: Under the skin, under what protects us, there is another protective structure, right? The muscles.
_AM: Beyond the fact that they have a protective function, their main function is mobility. Muscles are those that will allow movement and flexibility of the entire body, and are one of the most important tissues to preserve the rest of the systems, since they are responsible for keeping the body at a constant temperature.
_I: Oh, I didn't know that. What I would be fascinated to understand is how they move. Because, perhaps moving is so naturalized, that we have no idea of the things that must happen for us to move a simple muscle.
_AM: Well, it could be said that this system is a complex network interconnected to the nervous system, which sends and receives signals from the muscles to move.
_I: How do the muscles appear?
_AM: At the beginning of cellular development, cells used to live in liquid environments, mobilized by water, so the environment was responsible for allowing their mobilization in the environment. But they depended exclusively on the currents to find food. For this reason, some prokaryotic cells developed the ability to move using a small extension that they were able to shake, making it spin in circles, allowing them to move through space.
_I: Oh, like a sperm.
_AM: Likewise. However, eukaryotes found a more complex form, which was the articulation of cell groups, which specialized in mobilization. In this way, after millions of years of evolution, myocytes, muscle cells, emerged.
_I: How did they communicate? That is, how did they know to move?
_AM: Due to electric shock.
_I: As if they were electrocuted…?
_AM: Well, enough to make them vibrate without killing them. Electrical pulses are small discharges caused in the nervous system that transfer information from one point to another from the axons (extensions of neuronal cells, which discharge a neurotransmitter molecule called acetylcholine at the nerve terminals, which transports energy to the receptors. cell phones). It discharges an electrical current to the muscle cell membrane, producing a synapse (connecting bridge), which causes the cell membrane to react, depolarizing it. This means that a cell usually protects itself magnetically, for example by putting all its positive charge outward to repel any approaching particles, and opens itself to receive if its negative factors extend outward, making them receptors. Thus, acetylcholine drives this polarity change, so that the cell receives this discharge of energy, which will be processed by the mitochondria, producing the chemical reaction inside this cell, which has a peculiarity: they distend. or contract based on said discharge.
_I: Yes, like a minimal electroshock, which a body can feel when it perceives current in which the muscles tense, but in microns of power.
_AM: The reason this happens is because muscle fibers, said muscle filament cells, are made up of two main proteins called myosin and actin, intertwined like tissue. Myosin is thick and dark, while actin is light and thin, and both react to this electrical pulse by contracting together or distending, which produces muscle elasticity.
_I: Wow, I find it fascinating that what we see as common when moving any part of the body comes from such simple and tiny mechanisms. In other words, a muscle is made up of a succession of long cells made up of these proteins, which react to electrical pulses from the nervous system.
_AM: They receive these discharges due to environmental factors. The 5 senses receive external data that are assimilated by the brain, which takes the download to the appropriate muscle so that it reacts depending on the circumstance.
_I: It's amazing, because everything happens in thousandths of seconds... Also, in so many cells. How many muscles are there in a human?
_AM: About 650 muscles, which are divided into three types: Smooth, Cardiac and Striacal. Smooth muscles are those that produce the contractions of the internal organs and that we cannot control at will, as they are normally part of the parasympathetic nervous system, which implies constant functioning of the visceral system. The cardiac muscle is known as the “myocardium,” and it is an involuntary muscle that makes up the heart, of which we also have no voluntary control. Involuntarily, the heart beats 60 to 100 times per minute, pulsing blood through the circulatory system. The best-known muscles are those that we have the ability to control or be at least aware of their movement: the striac muscles, also known as skeletal, since they are connected to the skeletal system. Its function is to move the structure of the body and generate action through the contraction or distension of the muscle cells that cause the elongation of the tendons that connect bone to muscle, and thus, like a kind of elastic spring, the structure is moved.
_I: Why is it called muscle?
_AM: The word comes from the Latin “muso” which means mouse.
_I: Mouse?
_AM: Yes, “muscle” refers to a small mouse (“ulo”= diminutive). This is because the movement of the leg muscle up and down gave the sensation of a mouse moving inside, which is why this muscle was called “thigh”. In Greek the word muscle is “myos”, and from there words like myosites and myocardium arise. It later spread to all other muscles. The accumulation of proteins that receive electrical tension constantly makes muscle meat a high source of nutrients and proteins that store the body's energy heat reserves called "calories", which are used for movement and to keep all organs in motion. a suitable temperature.
_I: Why is 37 degrees appropriate?
_AM: At more than 30 degrees, most viruses and bacteria, microbes and parasites usually die, so maintaining this internal temperature and pressure keeps us safe from infections from external agents that are usually at room temperature. So the muscles take care of this.
_I: Interesting.
_AM: Muscles are usually organized in pairs called agonists (those that contract to perform an action) and antagonists (those that relax to perform the opposite action. Muscle tissues are made up of fibers made up of myofibrils arranged in striations. , which are incorporated within a layer called sarcolemma, which contains them within a set of various similar structures called fascicles, which in turn are arranged in groups. The endomysium is the interior of the muscle, and the ducts extend into it. circulatory or blood vessels. All contained by the epimysium, whose ends become tendons. The consumption of fibers in the diet helps maintain muscle tone, which allows stability and flexibility, agility, of the entire organism.
_I: It's like, without muscles, not only would we not be protected, but we would not have any movement...
_AM: Muscles are the visible body of universal systems, they are the millions of common cells of the cosmos that perform transformation functions. There are many forms of life in the universe, and most are useful as energy reserves to protect other sensitive systems.
_I: How? Wait, I didn't understand this...
_AM: Most living beings are functional to primary systems. Reserves of energy, of data, that the main systems use for development. They protect themselves by surrounding themselves with them, obtaining energy from them, and at the same time, these cosmic muscles live off this energy generated by sensitive systems.
_I: How to understand it more logically? That is... As a human.
_AM: Well, we could compare it to a sports stadium. Imagine football. The 22 players will function as nervous and circulatory systems, as well as the endocrine system. The players will generate nervous tensions and the circulation of hormones that will generate reactions in the stands. The stands are like a set of myocytes, organized into two teams: agonists and antagonists, which will exert opposing forces depending on the signals sent by the athletes' play. The waves of electrical reaction will move the myocytes in one direction or another, causing an overall movement that will affect the players' performance. In a way, the players provoke reactions in the stands, the public, to receive their strength, prompting them to play with greater intensity. Thousands of people feed the action of 11 players representing the central systems.
_I: This means that there are more or less 95% of beings in the universe that do not make their own decisions, but instead generate energy and response to the pulses of other beings that do set their intention... This is like... Ugly, I mean , it sounds to me like the majority of people are cells used by a few.
_AM: What does it sound like to you?
_I: To manipulation, that is, to what many humans try to avoid in life, which are systems of oppression, conspiracies in which humanity is controlled by a few...
_AM: Why does it seem unfair to you?
_I: Because it's like a few live off of all of us.
_AM: I don't understand what the problem is...
_I: Damn, I mean, some put in the strength, the action, the work, so that a few can stay protected inside while the others put in their bodies.
AM: What's the problem?
_I: That seems unfair to me.
_AM: How would you do it?
_I: Let everyone be free to do their own things…
_AM: They are called single-celled organisms, they have functioned for millions of years, prokaryotes and eukaryotes that have not gone any further than being a single-celled culture in the oceans and swamps.
_I: You mean we wouldn't be human without this system of “oppression”?
_AM: Your human mentality, your history, has made you interpret this as a system of oppression, but it is not, it is a system of order. If every cell in your body wanted to be free of the body, you would cease to exist. There was no purpose in being human… Or in being anything, really. You understand? Unicellular organisms are grouped into multicellular organisms because each one has one attribute but lacks another. Most cells have the attribute of action, but not intention. They have strength, but they don't know what to use it for. Then a neuron tells it what to do and where, and so thousands of these cells find a purpose. Without that neuron, the others would have died. Your vision of freedom does not come from the horribleness of the system, but from the diseases produced in an organism. Humanity today is experiencing a process similar to Tourette's syndrome, in which the nervous system is functioning incorrectly, leading the muscles to act erratically, aggressively, and releasing tension and actions without any sense or control. That is what makes you see that the system is bad, it is that there are sick neurons, not that the system is bad.
_I: Oh… I understand.
_AM: It's like judging all waters because there was a tsunami in Sumatra. You understand? Has no sense. There are certain human neurons that are functioning poorly, and this makes you see this as a system of oppression, without freedom. In all dimensions, in all systems, we all need everyone. Symbiosis is essential. The innate capabilities of each cell are useless without the interaction of the others, and knowing the potential of each one helps to recognize the place that one can occupy. Not all cells can be bosses, not all can be employees, not all can be teachers, or farmers... Diversity leads us to need each other to become a Being. Thus, most cells have the capacity to action, while a few possess the impulse, and a few others the intention, planning, idea... Thus it is, then, that what you consider an oppressive system in the human revolutionary vision, is nothing more than the most perfect symbiotic system of universal action. .
_I: And why doesn't it work on us?
_AM: Because you are a species in the process of conscious evolution. You are practicing how this works on a mental level. You are looking for the inner power of each cell, and you consider that not having found it is because someone has taken it away from you. And no, it is simply the ability of others to manage that power that they have taken control of because you are not using it.
_I: Then… We must regain power…
_AM: And to do it you must know yourself. And knowing yourself means discovering your potential, not believing that being free means having the potential of others. That is unconditionality, the network, the interaction. The strength of the group arises from discovering the potentiality of each person shared in the group, receiving the nervous impulses that activate the action.
_I: The strength of the muscles is the whole of a species, and the brain lives through us, because we forget that our power is not to take control of the brain or separate ourselves by freeing ourselves from it, but by taking the reins of our inner strength , knowing that it is for the whole.
_AM: We are all One, the question is in what do you place your strength to make that whole move. You just know what you can be...
_I: A bacteria, a prokaryote... In the ocean.
_AM: But overall you know that you can be much more.
_I: I take the strength and example of my muscles, well, knowing that the energy that protects the rest of the systems are the myocytes; the humans who put the strength to make civilization possible.
_AM: Recognizing that internal systems are the ministries and organizations that, if not sick, allow the strength of said actions for the whole.
_I: We are one, we just have to recognize each person's place, and from there, we can be everything.
_AM: Stand firm, recover the strength in you.
_I: I Am the Force.
_AM: And with her, be flexible. The key to this system is not power. You already know which one it is.
_I: …The Movement.
_AM: Then move! Exercise your body, activate your muscles, ignite heat and strength in you, and move forward in life. And in each act, you will know that you will be nurturing a being much greater than we all are...
_I: And that I Am.
