Muscle tissue is composed of muscle cells that functions to move the body's organs . Ability was due to muscle tissue able to contract . Muscle contraction may take place due to protein molecules that build muscle cells can elongate and shorten.
Composition diagram skeletal muscle tissue , muscle darikeseluruhan to the molecular level .
Muscle tissue can be divided into 3 types :
Muscle 1.Jaringan Polos
Smooth muscle tissue have fibers ( fibrils ) are homogeneous so that when observed under a microscope looks plain or striped .
Smooth muscle to contract in a reflex , and autonomic nervous bawahpengaruh . When the smooth muscle is stimulated , the reaction is slow . Saluranpencernaan found in smooth muscle , blood vessel walls , the respiratory tract .
Muscle structure Polos
2.jaringan skeletal muscle
Another name is skeletal muscle tissue because most of these types of muscles attached to the skeleton tubule . Contraction according to our will and under the influence of unconscious nervous .
Called striated muscle because when viewed under a microscope looks the dark and bright lines criss-cross along the transverse muscle fibers . Therefore another name of striated muscle is transversely striped muscle .
Striated muscle contraction is rapid when receiving stimulation , contracted in accordance with the will and under the influence of unconscious nervous .
Striated muscle function to move the bones of the skeleton and protecting the crunch.
Myocardial 3.Jaringan / Myocardium
Muscle tissue is found only in the middle layer of the heart wall . Structure resembles striated muscle , despite that cardiac muscle contraction reflex and reaction to stimuli is lambat.Fungsi heart muscle to pump blood out of the heart .
