The muscle movements are those that allow us to walk into a room or to drink a glass of water.
Some muscle movements are voluntary, ie consciously controlled, for example, can we move our feet to walk or move the hand to bring the glass to your mouth to drink water. Other muscle movements are involuntary, that is not the control, for example when they swallow the juice enters the digestive system through involuntary muscle activity digested without conscious perception of us the process of digestion.
In the body there are three types of muscle: skeletal, cardiac and smooth muscle (1).
Skeletal muscles (or barcodes) are under voluntary guidance. They weigh 40-45% of human weight and comprise the largest percentage muscle in the body.
Skeletal muscles are built from muscle bundles that are arranged neatly.
A small muscle can contain only few bundles of muscle fibers while the large muscles have hundreds strips. Nerve impulses leading to the release of acetylcholine (formula neurotransmitter) and induce thereby muscle. This starts a chain of events in which sodium, potassium and calcium act in the filaments of muscle proteins (myosin and actin), causing them to slide over each other causing the contraction of the muscle.
Every muscle contains a set of specialized nerve fibers that determines the strength of contraction along with another set of nerve fibers in the tendon that defines the stretch. The information obtained from these fibers is carried to the brain and are essential for muscle activity.
> Smooth muscle acts involuntarily and ensure the movements of the internal organs, for example the peristaltic intestinal movements, the contractions of the uterus (during childbirth), the bladder moves, the bronchi of the lungs and the walls of blood vessels. Smooth muscle is formed from elongated, fusiform cells. In most organs with cavities, these cells are organized in sets as an outer layer along a topsheet going circular inwardly. The smooth muscles respond to neurotransmitters, hormones and changes in the composition (acidity) of the fluid that surrounds the fibers.
> The heart muscle or myocardium is found only in the heart. It is a single type of muscle is able to contract rhythmically about 100,000 times a day to stimulate the blood in circulation. The heart muscle is similar to skeletal muscle structure. The contraction induced by the autonomic nervous system, hormones, and the stretch of the muscle fibers. \
Role of muscle is:
- to provide energy in the moving parts of the body – a different amount of energy spent when we raise a glass of water than when we lift a travel suitcase to put her in the car.
- to produce heat – if you go for a brisk walk a cool day, we will see as we walk that muscles produce heat and after a while you start to sweat.
- to work together with ligaments supporting the joints and tendons entering the muscles to the bones – ensure the knees, elbows and other joints in shape and mobility.
> Problems caused by toxins
Alcohol and other toxic substances can have a negative impact on muscle health. Studies in alcoholics have shown that those who drink excessively experienced progressive weakening of the heart and skeletal muscle, presumably as a result of induced ethanol breakdown of muscle proteins (2).
Alcohol consumption increases the risk of stroke. This is because damage can be caused by alcohol the arterial muscles, which causes an increase in blood pressure. The lesions in the skeletal muscle can be so severe in some alcoholics that can eventually lead to severe disability and inability to walk.
The most common disorder of the muscles is the injury (1), which is followed by symptoms caused by the inadequate supply of a muscle blood (including, myocardium).
Stretches or damage to muscle can cause bleeding into the tissue. The healing leads to the formation of a scar on the muscle that reduces the physical size.
> Problems caused by poor blood circulation (1)
Good muscle function depends on the good supply of blood. Peripheral vascular disease, which restricts the supply of blood, causing muscle pain during exercise. Angina, chest pain caused by inappropriate blood supply to the heart muscle is observed in coronary artery disease. The cramp is a common and painful condition caused by prolonged contraction of a muscle. Cramp normally takes a few seconds and can be caused by lack of blood flow, poor posture, stress, fatigue, and sometimes very intense exertion or exercise causes accumulation of lactic acid in the muscle.
In carpal tunnel syndrome, pain, swelling (edema) and numbness in the hand have the effect of compressing a tube in the fruit from which nerves pass, tendons and blood vessels. Studies suggest that people with carpal tunnel syndrome may benefit from taking pyridoxine (50mg) (3).
The Gravis gravis is a disorder in the transmission of nerve impulses to the muscles. Often it starts causing fall of the eyelids and double vision.
Other autoimmune related diseases muscles are systemic lupus erythematosus and rheumatoid arthritis.
Beneficial Supplements & Herbs for Health Muscles
> Glucosamine KCl – involved in the formation of glycosaminoglycans, the network to which the collagen is structured for the formation of joints, tendons and ligaments (4).
> Fish oil – contains omega-3 essential polyunsaturated fatty acids that are involved in the health of cell membranes and nerve health. The omega-3 provide the material for the production of anti-inflammatory prostaglandins (PG3). It reported improvement in symptoms of rheumatoid arthritis in patients taking fish oil supplements.
> The antioxidant vitamins C and E, zinc, selenium, manganese and copper are involved in the metabolism of essential fatty acids and health of cells and nerve.
> Calcium and vitamin D – calcium is important for muscle contraction, the health of nerves and with vitamin D for building bone.
> Calcium & Magnesium – muscle contraction requires both these metals.
Administration by magnesium supplement has been shown to be effective in the treatment of muscle cramps. A study in Sweden with 73 women who experienced leg cramps because of pregnancy showed that supplementation with magnesium for 3 months significantly reduced the incidence of cramps, compared to taking placebo (7).
> Devil’s Claw – used for gout, gouty arthritis, muscle pain, and various forms of muscular rheumatism. Studies have shown that extracts of Devil’s Claw have antiinflammatory properties and can therefore help to reduce the pain.
> Evening Primrose Oil (Evening Primrose Oil) – containing essential omega-6 polyunsaturated fatty acids that are involved in the health of cell membranes of nerve and myelin coat covering the nerve endings.
> Vitamin B6 – the vitamin B6 has been associated with carpal tunnel syndrome.
General tips for keeping muscles in good condition
Eat five servings of fresh fruits and vegetables every day. This will offer minerals and especially sodium is necessary for the health of muscles. Drink lots of water every day at least a liter. For the health of muscles necessary health of the nervous system which is fed with B vitamins, calcium, magnesium, and essential fatty acids. Workout toned your muscles by walking, swimming and other exercises will help you stay in shape. The exercises proposed for the health of muscles include besides the weight transfer exercises (walking, running, dancing, etc.), weight lifting exercises that strengthen the muscles. These two types of exercise are also known as weight-bearing exercises and basically include exercises in which bones and muscles “work” against gravity.
