Cardiac muscle owes its striated appearance to the arrangement of thick and thin filaments that make up the contractile apparatus. Electron micrographs of cardiac muscle reveal a banding pattern of myofibrils similar to that observed for skeletal muscle. Like skeletal muscle, these bands are referred to as the A band, I band, and Z disk.

define muscle fibre: skeletal and smooth muscles (not cardiac muscles) types of and light I band are aligned giving the muscle cell a striated appearance.

The Z lines come closer together. The I-band exclusively contains thin filaments whereas the H-band contains exclusively thick filaments. Skeletal muscles are divided into two muscle fiber types: Slow-twitch (type I) muscle fibers contract more slowly and rely on aerobic metabolism. They contain large amounts of mitochondria and myoglobin, an oxygen-storage molecule. As seen under a polarization microscope, the A-Band in skeletal muscle fibres is so named because it is anisotropic in its refractive index which is a characteristic of orderly crystalline structure.
