Cardiac muscle
Intercalated discs and myobrils are seen in greater detail in this high magnification image of longitudinally-sectioned cardiac muscle fibers. Intercalated discs are composed of the interdigitating plasma membranes of adjacent fibers along with adherent and communicating cell junctions. 1000x
