What are the function of muscle in the human body?
muscles in the human body perform several important functions. Their primary function is movement, voluntary and involuntary, and also support the body and help keep posture. Healthy and strong muscles also stabilize many joints of the body and determine the overall strength of the body. Another feature is to generate heat as a by -product of other processes.
The most visible function of muscles is movement. Voluntary movement involves conscious effort by individual and examples include walking, bending, twisting and lifting. It also includes fine engine movements such as writing or tool playback. Muscle type usually responsible for voluntary movement is called skeletal; It is a striped muscle that has a striped or striped appearance under a microscope. Through the skeletons they are attached to the bones and produce locomotion by infection or tightening and relaxation.
The second type of movement is involuntary and there is an automatic clinker. Examples include breathing, food movement through the digestive system and beating the heart. These movements occur without jaThe individual's efforts and many of them maintain their lives and continue if a person is asleep or unconscious. Different signals control these involuntary effects and the muscles that perform these movements are often smooth, except for a striped heart muscle.
Another function of muscles in the human body is support. Skeletal muscles are constantly working to support the body and help keep posture, whether one sits or stands. The muscles also support, stabilize and strengthen the joints by holding the bones in the correct position, especially in areas where parts of the joint do not fit closely, such as shoulders and hips. Skeletal muscles are also vital in determining the overall body strength of the ability to perform different physical tasks. Maintaining strong muscles is useful for general health and well -being.
muscles are also important for maintaining proper body temperature. Since muscles consume nutrients that provide strength to move, partT energy generates heat - estimated up to 75% of energy produced in this way. Since the skeletal muscle includes a large percentage of total body weight, the amount of generated heat is significant and plays an important role in maintaining a healthy temperature.
