During muscle activation, ditin hind's Calcium at Specific Sites, thereby increasing its stiffness, and Cross-bridge attachment to actin is thought to active muscle. free up binding Sites for ditin on actin, thereby reducing titin's free - Spring length, thus increasing its Stiffness and fonce upon Stretch of Titin is a large abundant Protein of striated muscle. Titin's Primony functions are to Stabilize the thick filoment, Center it between the thin filaments, Prevent overstretching of the Soc. Sarcomere, and to recuil the Sarcomire like a spring after it is Stretched. . A muscle fiber generates tension through actin and myosin cross-bridge cycling. While under tension, the muscle may lengthen, shorten, or viemain the same. Although the term contraction implies shortening, when referring to the muscular System, it means ithe generation of tension within a muscle fiber.
How and why does the Titin molecule start to signal muscle growth when we stretch a muslce under tension or when it enters its decending limb lenght? I thought the titin molecule was suppose to prevent the muscle from being too stretched
