What are the function of the muscle system?

In humans, muscles are one of the most abundant soft tissues that only overcome the skin. There are three main types of muscle tissue: heart tissue found in the heart; skeletal tissue that allows voluntary movement; and tissue of the smooth muscle, which is found mainly in the digestive tract. The muscle system functions are not always obvious and include voluntary and involuntary movement, visceral support and thermogenesis or heat generation. Muscles require a high protein diet to maintain their highest form. Unlike involuntary heart muscles, the skeletal muscles produce voluntary movement. These muscles connect with bones through tendons and their contractions cause tendons to pull and move the attached bones. The smooth muscle, mainly located in the digestive tract, is under involuntary control and produces peristalsis, pushes the food through the digestive tract.

Authority support is one of the most important functions of the muscle system. Muscles of the abdominal wall such as rectus abdominis, Cross abdomen and external/inner oblique, all hold the abdominal organs such as stomach and intestines in place. If the abdominal muscles are burst, the small intestine may protrude; This is known as a hernia and can be life -threatening. Muscles and ties prevent the internal organs to fall down inside the body and when these muscles cannot act against pressure from above, the organs can protrude from the rectum or genitals.

Another feature of the muscle system is to maintain proper posture. latissimus dorsi , muscles attached to the shoulder blades, pull the shoulders back. The hip flexors keep their legs in the right position for a permanent posture and the cervical spine holds their heads. Proper posture requires the spine to monitor its natural curvature, with the least possible tension on the muscles.

Thermogenesis or heat generation is also one of the function of the muscle system. Muscle produces the energy it needs to download in the process knownLike glycolysis - the decay of glycogen. It is an exothermic chemical reaction, which means that it produces more energy, but only some energy focuses on muscles. The rest of the energy spread throughout the body like heat; Muscle contractions are 85 percent of the heat necessary for homeostasis. When body temperature drops too low, the brain induces shivers to produce more heat.
