Smooth tab.
Smooth muscle tissue consists of elongated cellular elements. It is found mainly in the walls of visceral organs and blood vessels.

Striated tab.
Striated muscle tissue is composed of fibers. These fibers represent the fusion of many cells into a single functioning fiber (syncytium). Under the microscope, these fibers appear to have a transverse pattern of light and dark banding.

Cardiac tab.
Cardiac muscle tissue is also composed of banded fibers.
However, its fibers have a branched character. Cardiac muscle tissue is found only in the wall of the heart.
