In electron micrographs of cross-striated muscle, the Z-line (from the German "Zwischenscheibe", the disc in between the I bands) appears as a series of dark lines.

I band sarcomere

Thus each sarcomere includes repeating units between two Z lines in linear order as Z line, I band, A band, I band and next Z line. Electron microscopic studies have shown that the striations are due to the regular arrangement of 2 types of protein filaments. 'A band' contains a set of thick filaments formed of the contractile protein myosin.

I band sarcomere

Each sarcomere extends from one Z disc to the next. Thus each sarcomere includes repeating units between two Z lines in linear order as Z line, I band, A band, I band and next Z line. Electron microscopic studies have shown that the striations are due to the regular arrangement of 2 types of protein filaments. 'A band' contains a set of thick filaments formed of the contractile protein myosin. A sarcomere is defined as the distance between two consecutive Z discs or Z lines; when a muscle contracts, the distance between the Z discs is reduced. The H zone—the central region of the A zone—contains only thick filaments and is shortened during contraction.

Thin filaments are pulled by the thick filaments toward the center of the sarcomere until the Z discs approach the thick MCAT Question of the Day: Sarcomere Anatomy: I Band, A Band, M Line, Z Line, and H Zone - YouTube.

Each sarcomere extends from one Z disc to the next. The functional contractile unit of a muscle is the… The thick filaments are anchored at the middle of the sarcomere (the M-line) by a protein called myomesin. The lighter I band regions contain thin actin filaments anchored at the Z-discs by a protein called α-actinin. The thin filaments extend into the A band toward the M-line and overlap with regions of the thick filament. Learn bands sarcomere with free interactive flashcards.
