MUSCLE TISSUE

Muscle tissue composed of muscle cells whose function is to move the organs of the body. Due to the ability of muscle tissue can contract. Muscle contraction may take place because the protein molecules that build muscle cells can be elongated and shortened.

KINDS OF MUSCLE TISSUE

Muscle tissue can be categorized into 3 types, namely

------------Smooth muscle tissue

Striated muscle tissue

Cardiac muscle tissue

Muscle tissue smooth

• Have smooth muscle tissue fibers (fibrils) are homogeneous, so that when observed under a microscope looks plain or striped.

• Smooth muscle reflexively contract and under• The influence of autonomic nerves. When smooth

muscle is stimulated, a slow reaction. Smooth muscle found in the digestive tract, blood vessel walls, respiratory tract.

Smooth muscle structure

Striated muscle tissue• Another name is the skeleton muscle tissue because most of these types of

muscle attached to the frame of tubule. Contractions according to our will and under the influence of nerve aware.

• Called striated muscle because when viewed under a microscope looks of light and dark lines criss-cross along the transverse muscle fibers. Therefore, another name of striated muscle is the muscle transverse stripes.

• Called striated muscle because when viewed under a microscope looks of light and dark lines criss-cross along the transverse muscle fibers. Therefore, another name of striated muscle is the muscle transverse stripes.

• Striated muscle function to move the bones and protect the frame from heavy impact.

Muscle tissue heart / myocardium

Muscle tissue is found only in the middle layer of the heart wall. The structure resembles striated muscle, although once the heart muscle contraction and the reflex response to slow stimuli. Heart muscle function is to pump blood out of the heart.
