Muscle
Muscles are an essential part of the human body’s motor system. They are the primary source of movement in the body, movement from place to place, maintenance of firmness and erection, and are responsible for the movement of internal organs in the human body. The muscles are divided into three types: planned cardiac muscles located only in the heart, unplanned smooth muscles located in the lining of the blood vessels and internal organs, and the involuntary structural muscles that form the majority of the musculoskeletal system in the human body, responsible for the movement of the trunk and extremities and erection.
The skeletal muscles in the body consist of a large number of muscle cells called muscle fibers, where these fibers combine in the form of long, thin and firm bundles. These fibers contain two types of protein strands, namely myosin and actin, which are responsible for the contraction of the muscle. These fibers (myosin and actin filaments) are placed in a resting position that is not tight and unconnected, and when the muscle contractes, these threads are bound together and their length and length increase. Since skeletal muscles are usually associated with bones, where each muscle has an origin and a stimulus, muscle contraction results in the movement of bones and joints in the trunk and extremities.
The skeletal muscle gets the energy needed to contract and move from the burning of glucose and fats that reach the body through food, producing a compound called adenosine triphosphate (ATP), which is the main fuel for muscle contraction. The stronger the fibers and the muscle grows as a result of the muscular effort exerted by the body, the greater the human exertion of muscle has developed stronger muscles and more solid, and more flexible, and this is observed in athletes who exercise in various forms.
cramp
Muscle tension is an involuntary constriction of a single muscle or muscle group, so that the muscles become stiff, tight and sore, and sometimes this tension may result in muscle rupture. Muscle tension usually occurs in the muscles of the hind leg or foot, but may also occur in other muscles, such as the muscles of the hind thigh, abdomen, hands, arms, and thorax.
Causes of muscle strain
Muscle tension occurs due to one of the following reasons:
- Blood ischemia of the muscles.
- Do not prepare for muscle work (warm up) before starting the exercise as a lack of elongation exercises.
- Muscle inactivity due to lack of work requires muscle exertion.
- These muscles are subject to sudden bruising, causing a tremendous and sudden strain on the muscles of the body.
- Muscle fatigue.
- Drought, so that the body loses a lot of fluids.
- Potassium or magnesium deficiency.
- Do exercise in a warm environment.
Other possible causes of muscle strain include:
- Make a muscular effort that exceeds the capacity of the muscle, such as a heavy weight load, or long-distance jogging.
- If the leg muscles are tight, one of the reasons may be to stand for a long time without taking a rest, sitting for a long time, or having the legs in an inappropriate position during sleep.
- Exposure to cold, such as the use of cold water.
- Pregnant women are usually subjected to muscle strain in the leg and thigh area, due to lack of calcium and other minerals.
Symptoms of myocardial infarction
Muscular rupture occurs when a violent activity occurs, such as carrying a heavy weight suddenly and quickly, during exercise, or during the completion of any work, where a part of the muscle and rupture occurs with hemorrhage in the blood vessels and severe pain. In the case of a rupture of the muscles of the man shows the following symptoms:
- Pain in the man, and be very sharp and continuously.
- Swelling, bruising, and sometimes bruising as a result of rupture.
- Inability to stand, walk or use the injured part.
- Numbness of the man’s fingertips, and a feeling of weak sensation in the area surrounding the muscle rupture.
Treatment of posterior thigh muscle
The hind thigh muscle consists of three muscles extending from the bottom of the pelvis. It joins the same tendon to the top of the leg bone. These muscles flex the knee joint and are of great importance as they are responsible for the lower limb movement in jogging, climbing and jumping. The back muscle injury is frequent in sports activities or when such activities start, such as jogging or football. The incidence ranges from muscle tension (cramping) to partial or complete rupture of the muscle.
A muscle strain in the hind thigh muscle is not a serious problem, but muscles will become more prone to muscle rupture, as well as other pelvic and lower back problems such as low back pain or sciatica. Therefore, in the event of a tightening will be limited range of motor, and therefore the patient will need exercises for elongation of muscles, in addition to a gentle massage to relieve muscle tension and increase the range of movement.
In the case of a muscle rupture of the posterior thigh muscle, the patient will experience sudden severe pain with a feeling of popping, pain in the back thigh area and below the buttocks when walking, or extending the man up, or bending the body down, in addition to congestion and bruising, so the patient will need the following treatment:
- Treatment of muscle rupture begins to stop movement immediately.
- Cool the snow-covered section in a cloth towel and avoid placing snow on the skin directly for fear of skin being burned. Ice is used for 20-30 minutes every three to four hours or until the swelling subsides.
- Connect the affected part with a compressive strap to prevent swelling.
- Lift the affected part to a level higher than the level of the heart when sitting or lying down.
- Take painkillers to relieve pain and swelling.
- In some cases, muscle stretching and strengthening exercises may be performed, but after consultation with the therapist and under his supervision. In severe ruptures, surgery should be performed to patch and break the broken muscle fibers.
- Muscle tension sometimes leaves the affected muscle, making it vulnerable to injury again during severe stress.
Types of muscle strain
Four types of muscle strain can be identified:
- Muscle tension caused by fibrosis in the muscle tissue, which causes limited movement, and this type of muscle tension does not accompanied by severe pain and requires rest for a limited period.
- Muscle tension caused by potassium or magnesium deficiency, usually occurs automatically in the elderly, or because of lack of calcium as in the case of pregnant women, and accompanied by this type of tension severe pain.
- A muscle strain that usually affects adults and occurs during the night during sleep and rest.
- Muscle strain caused by abnormal disorders of the body fluids, such as liver cirrhosis or renal failure, where fluid accumulates in the body cavities causing muscle spasms.
