The muscle tissue is formed by a responsible mesodermal derivation of the movement of bodies that are parts of the body of a living being that play a role distinct from the bodies is formed by cells very elongated called muscular or myocytes fibers which is a Spindle-shaped and multinucleated spindle cells are eukaryotic cells that have more than one nucleus inside with the ability to contract very easily, in addition to each of the muscle fibers They are surrounded by a thin sheet of connective or connective tissue that is a heterogeneous set of organic tissues that share a common origin from the embryonic mesenchyme originated from the mesoderm.
The muscle tissue is composed of three types of tissues such as smooth muscle tissue, striated muscle tissue or skeletal, cardiac muscle tissue.
The smooth muscle tissue, is the one formed by the union of several long cells which are prepared in layers mostly in the walls of hollow organs such as the digestive tract or blood vessels. but in this way they find smooth muscle cells in the connective tissue that affects certain organs such as the prostate and seminal vesicles and in the subcutaneous tissue, which is when it occurs in certain regions such as the scrotum that are bags that are formed by the skin that covers mammalian testes and nipples.
The striated muscle or skeleton, are those that are formed by the very long cells covered by an outer membrane of connective tissue called empimisio. In addition to they are part septa that are septum that is divided in a complete or incomplete way from a cavity or parts of the body in an animal that are directed towards the interior of the muscle.
The cardiac muscle tissue, are those that are composed of cells elongated also have transverse striations of the arrangement of contractile proteins and can be easily distinguished from skeletal muscle fibers by the fact of having one or two cores.
