Our made up of a bunch of

Our muscles allow us to do amazing things maintain our posture or produce heat even blink. When You flex or (contract) your muscles you ar shorting them to enable a sort of pulling force. Now the Muscle Tissue Characteristics They are made up of contractible fibers. Red V White Muscle fibers, Red is the slow-moving fibers They have a Greater Number or amount Of Mitochondria They contain high concentration of           myoglobin. They also move at a slow rate but do not fatigue thanks to sustained contraction. Postural muscles which are opposed to gravity. White muscle fibers contain little myoglobin/Mitochon They move fast and rapidly and undergo something called anaerobic respiration.Now we move to the cell itself we call it sarco mmila this cell like many others maintain a membrane potential so that impulses of the muscle can travel through it. Now Vasoconstriction Constriction and dilation of a blood vessel´s walls are the main things that results in smooth muscle contractions. Peristalsis are a wave like Motions that along the digestive tracts that the smooth muscle can produce. Now we go to skeletal muscle fibers every single one of these are a cell. Muscle fiber cells are cylinder shaped cells with a huge amount of nuclei inside of these cells are (Dark a bands,Light i bands,many Nuclei,Myofibril,Mitochondria and Saracomma. The Myofibrils contain thick filaments and thin filaments.Ultrastructure of thick Filaments: the thick filaments have something called tails and heads. The tails twist and the heads are just a are just round structures that go throughout the entire twist. The Ultrastructure of thin filaments include Troponin complex,tropomyosin and actin. The skeletal muscles are made up of a bunch of discs and bands. There’s a pattern it goes Z-disk H-zone Z-disk and That is only on one side the other is I-Band A-Band I-Band. When you flex or tighten your muscles they compress down and leave you to fell a harder surface then when you are just sitting down. Our muscles are very complicated they have mixtures that are Ca2atoms diffuse from the sarcoplasmic reticulum into a sarcoplasm bind to a bunch troponin molecules. Or things like a transverse tubule or a (t tube) that is well developed in skeletal and cardiac to transport calcium. Or just something as simple as a muscle spasm you could have it in the skeletal or smooth sections I thought that it was just your whole muscle that did that. We as a human race still have things to find so think when you get a cramp or a little twitch it’s not as easy of a thing that you would think. It’s a huge puzzle of things that are intertwined and smushed together.
