WebSep 22, 2024 · 3) Increasing the sarcomere length slightly again removes any opposing actin filament overlap. Consequently, all the myosin heads can extend and pull the actin filament towards the M-line. This particular region of the length-tension relationship is known as the optimal length, as it is the length that allows the most amount of active tension.
