Different bands of a sarcomere
WebThe sarcomere is split into the A and I bands, H zones, M lines, and Z discs. A band: Darker coloured band where thick myosin filaments and thin actin filaments overlap. I band: Lighter coloured band with no thick filaments, only thin actin filaments. H zone: Area at the centre of A band with only myosin filaments. M line: Disc in the middle of the H zone that … WebJul 7, 2024 · Sarcomere consists of different filaments along with the light and dark bands.
