Skeletal muscle

Cardiac muscle

Smooth muscle

is divided into three types

Functión

It is predominant in contractility, this capacity enables a large number of movements.

Made up of muscles that shorten when contracted and lengthen when relaxed.

Composed by:

By specialized cells called muscle fibers.

I generate the movements of the organism, voluntary and involuntary.

It maintains posture and serves as protection for other organs.

Composed by:

What is it?

Cardiac muscle cells and forms part of the heart wall.

The sarcoplasm surrounding the nucleus contains numerous mitochondria, glycogen granules, and lipofuscin pigments.

The cells of this tissue have single, central nuclei and also form highly specialized end junctions called intercalated discs, which facilitate nerve impulse conduction.

They are elongated and branched cells with a central nucleus.

What is it?

Filiform and cylindrical cells, known as muscle fiber.

They are cells that have a large number of mitochondria.

The contractile proteins are regularly arranged in dark bands (mainly myosin or also actin) or light bands (actin).

It is found in the walls of hollow viscera and in most blood vessels.

Also known as visceral muscle that participates in involuntary movements.

Mononuclear cells with the nucleus in the central position.

Its cells are spindle-shaped and do not have striations or a system of tubules..
