Web13 de ago. de 2024 · The mechanism of contraction is the binding of myosin to actin, forming cross-bridges that generate filament movement (Figure 6.7). Figure 6.7. When (a) a sarcomere (b) contracts, the Z lines move closer together and the I band gets smaller. The A band stays the same width and, at full contraction, the thin filaments overlap. Webtissue, in physiology, a level of organization in multicellular organisms; it consists of a group of structurally and functionally similar cells and their intercellular material.

Web10 de ago. de 2024 · When a muscle contracts in our body the distance reduces between the Z discs. The central region of the A zone (H zone), contains only thick filaments (myosin), and became short during contraction. H zone becomes smaller by increasing actin overlap and myosin filaments, due to this muscles shorten.
