Skeletal muscles are a type of striated muscles attached to the skeleton, made up of cells or elongated, multinucleated their cores located on the periphery fibers. The musculoskeletal system is vital for movement and other motor functions. The musculoskeletal system plays an important role in coordination of movement, too.
Obey the organization of actin and myosin proteins and confer that striation which is perfectly seen under a microscope. They are used to facilitate movement and maintaining bone-joint union through his contraction.They are generally voluntary contraction (through nervous innervation), although they can contract involuntarily.
The human body comprises about 90% of such 10% muscle and cardiac muscle and visceral.
Muscles have a great capacity for adaptation, changed more than any other organ both its content and its form. In severe atrophy can return to reinforce in a short time, thanks to training, as with the disuse atrophy leading to a decrease in muscle size, strength, even reducing the number of cell organelles.
If it is immobilized in shortening position, after a short time adapts to his new length requiring training base stretches to return to its original length, even if left stretched a time, it can give instability to articulate by adopted hyper-mobility.
The musculoskeletal system explained
The muscle due to its high power consumption, requires a good blood supply to bring you food and eliminate waste, that by the pigment of muscle cells, give the muscle a reddish appearance in the living being.
In the endplate (neuromuscular junction or synapse) the neurotransmitter acetylcholine (ACh) is released, this neurotransmitter acts in the sarcolemmal opening channels that allow indiscriminately step of sodium and potassium.
The electrochemical gradient allows more sodium ions on entering these in large amount, an action potential occurs since the cell membrane is rich in fiber channels voltage-dependent sodium, stimulating muscle fiber.
The action potential originated from the sarcolemma, produces a depolarization of the latter, it said depolarization coming into the cell, particularly the sarcoplasmic reticulum, causing the release of calcium ions previously accumulated in this and the terminal cisternae.
Secretion of calcium ions leads to the actin-myosin complex, which makes these proteins to bind and rotate on itself, causing a shortening, later, the calcium ions can return to the sarcoplasmic reticulum for next contraction.
Microscopic view of skeletal muscle
Skeletal muscle is a tissue composed of spindle cells or muscle fibers, consisting of the following elements.
Sarcolemma, is the cell membrane, runs along the muscle fiber and its end is fused to the tendon, and this in turn is fused to the bone.
Sarcoplasm, muscle cell cytoplasm containing organelles and other elements that follow.
Cell nuclei, which are located in the periphery of the interior, in this case there are several cores to a single muscle cell.
Actin and myosin is a protein complex web of polymer fibers whose main property, call contractility, is to shorten its length when subjected to a chemical or electrical stimulus.
In a muscle cell we find between 1500 myosin and actin 3000. These proteins have a helical or helix, and when activated together and rotate so that produces a shortening of the fiber.
During a single movement several processes exist attachment and detachment of actin-myosin assembly. Each muscle fiber contains hundreds to thousands of myofibrils.
reticulum surrounding muscle fibers results from the invagination of the sarcolemma, this reticulum in turn contains a system of tubules (T muscular System) terminals and tanks containing large amounts of calcium, essential for working muscles.

In contrast to everyone else’s opinion, diabetic foods are not really a special kind of food that only the person with diabetes can eat. Every member of the family can eat diabetic foods it is even much healthier.
Some diabetic foods recommendations can be intriguing and might sound unbelievable, but you can actually eat meat with fat still in it. Yes you don’t have to be bothered by a nagging feeling after you have eaten meats with fat; it can be healthy for them. Eating in moderation can give you the guilt- free feeling. Fruits and vegetables with high-fiber contents are a must for diabetics.
You may not deprive yourself the foods that your body needs, starving yourself can even make your illness to develop faster. Deprivation from food means no vitamins and minerals that can be supplied into your body. The most important ingredient that the body needs for it to function the way it should, and staggers the production of antibodies that fights infections that are rapidly invading all of the vital organs inside the body. Eating a balanced diet and with balanced variety of the food groups, combined with taking a regular exercise is indeed a very good and wise thing to do.
The moment you felt something unusual is happening to your body or even before these symptoms occur, regular trips to the doctor’s clinic can be healthy. Catching an illness at an early stage can be prevented from developing into something that is incurable. It is highly recommended to eat diabetic foods even if you don’t have diabetes.

Love handles, they don’t look good
They sure don’t. Men actually prefer love handles as they claim that it looks very hot on women. Women, on the other hand, disagree as they say that this is what makes them look fat. What are love handles anyway and why the pun name? Love handles is accumulated body fat, located on the back where liver is. The fat accumulates fast and forms a round shape, giving the typical appearance of handles. They sure do appear quickly, however to get rid of love handles takes a lot of time. Many will give up in the process and this is wrong.

Get rid of love handles in 4 different ways
As you might have guessed it, it takes a lot of time to get rid of love handles. One must exercise and eat at caloric deficit, forcing your body to obtain needed energy from stored fat. For optimum fat loss I suggest performing exercise at proper heart rate.
There are several different ways of how to get rid of love handles, some might work well, some might not. Eat less is really hard for some. As some people pointed out, there are a lot of things that we are hard wired to want more than it is good for us. I don’t see how food addiction is a lot further from that. I don’t believe that people can’t make a choice to limit their food intake or to take the initiative to do some physical exercise to keep themselves healthy.
I had been fortunate that I never had to worry about my weight until about two years ago, at age 38, when I noticed that I can gain weight easily if I am not mindful. With extra weight comes love handles. So now I take two very simple steps: One, I lower the portion of my daily meals (not restrict any type of food, I even have chocolates regularly in small portions, so that I won’t fall into the pit that is occasional binging); Two, I walk two miles at a good speed everyday on my way to and from work. This may not be ideal for everyone, but I am just trying to point out that even without spending hours at the gym or cutting out all carbohydrate from diet or taking similar drastic measures, one can achieve some level of control.
Buying your own produce and cooking daily meals from scratch probably are a big help, and this practice is also cheaper than eating out, even at fast food places. I just refuse to believe that we have no control over our weight. Read more about losing weight on proper way here.
There is another approach that I found worth pursuing. Rather than focus on all the bad habits the obese people have, perhaps it would be more productive to focus on what good habits the “normal” sized folks have and attempt to emulate them. It’s not all that complicated. Clearly avoiding processed foods is key. Now all we have to do is take on that PAC. Yikes. At the end of the day, isn’t it always “just follow the money trail” and you’ll find the root of the problem? It is the same with love handles.
It is not easy to get rid of love handles, but in the end it is really worth it.
Sugar kills, but not always
Sugar is poison. If people just ate much less fructose and sucrose, their livers would start functioning better, and correct appetites would return. Sucrose is processed in the liver the same way that ethanol is. This is why children fed a constant stream of soda, sports drinks, and even juice can have “beer guts.” With elder people this results in formation of love handles.
I would suggest you to cut sucrose/fructose out of your diet, but keep other carbs and even drink whole milk. This way you could lose 20 pounds in three months. You will feel great, and full after eating about half as much as I used to. It is important to point out that will lower calorie intake you will also get rid of love handles. Not for good, but still.
As we all know heart.com is an American Heart Association’s that puts most efforts in reducing death caused by heart disease and stroke. They strive to put knowledge out there in order to help people live a healthier life by providing useful advice and experience.
How can you help too?
You can join the site and share in your experience. The registration is open and free for all. If you had stroke in the past and survived it your should definitely join and help others. At the end of the day stroke can be fatal and all advice you can share is useful to people who are in critical group (males, over the age of 50 with a history of stroke).
Studies indicate something else
As of late distributed on NY college an ascent in glucose levels may not speak to diabetes. Increment in glucose levels may be expected a fundamental therapeutic issue or some different reasons.
This is the reason anybody with diabetes truly ought to be seeing an endocrinologist. My mother is 89, forthcoming 90. She has sort 2 diabetes and uses insulin. Her endocrinologist keeps close tabs on her glucose level and has let us know various times that the key concern at my mother’s age is to not go too low. My mother’s target glucose level is much higher than it would be for somebody who is in his or her 50s or 60s, for instance.
Possibly essential consideration doctors, the great ones in any event, realize that elderly individuals with diabetes, especially on the off chance that they utilize insulin, shouldn’t try for tight control. Yet my estimate is that generally don’t. Which is the reason you have to see an endocrinologist. Sadly, we have a lack of endocrinologists in this nation. Since they don’t perform strategies, they aren’t paid exceptionally decently contrasted with different fortes, which is one motivation behind why med understudies don’t pick endocrinology. Only one more scourge on our U.S. social insurance framework. What’s more, one that is truly going to nibble us in the butt soon as more gen X-ers are diagnosed with diabetes.
Sum is not generally the same
One thing I have scholarly while helping my Grandmother through some restorative issues is that the measure of insulin taken at any given time is not a situated in stone sum. It is liquid, in view of your glucose readings. According to her specialist’s directions, she was to take a particular measure of insulin against all odds, unless her glucose perusing was high. All things considered, she could take a couple of units more. What was never imparted to her was that on the off chance that her perusing happened to be lower than ordinary, because of disease or generally.
For a time of time, she would wake amidst the night with sentiments of hypoglycemia. Her glucose meter affirmed it. Every time, her nighttime perusing (before supper) was marginally low, yet she took her typical measure of insulin. At to start with, her specialist’s reaction to this was, “well, have a yogurt before bunk,” which didn’t help by any means. I at long last persuaded her to take a marginally lower insulin measurements (2-3 units less) on the off chance that her nighttime perusing was lower. My thinking was that low glucose is much more risky than a somewhat higher than ordinary level. After a couple times utilizing my extemporized measurement go, her scenes vanished. Her sugar level is controlled, and her specialist is still indifferent (a totally distinctive issue, however regardless he affirmed the change we made).
Specialists working with the elderly are so concerned with abnormal states, that they never take a gander at the issues when they plunge beneath typical. They have to begin pondering the flip side of the glucose level extent.
How is your sleep lately?
