WitrynaCardiac muscle occurs exclusively in the heart. It possess considerable automatic rhythmicity and generates its own wave of excitation. The excitation can also pass directly from fibre to fibre in the cardiac muscle. It is not under voluntary control. It shows cross striations, but striations are much fainter than those of striated muscle. WitrynaCardiac muscle is striated muscle that is present only in the heart.

WitrynaCARDIAC MUSCLE Cardiac muscle is a striated fiber containing the same arrangements of contractile filaments as skeletal muscle. In addition, cardiac muscle fibers exhibit densely staining cross bands called intercalated discs (Fig 3). These intercalated discs join the muscle fibers end-to-end. They are Witryna9 lut 2024 · Cardiac muscle is striated muscle that is present only in the heart.
