Web7 mei 2024 · According to this theory, muscle contraction is a cycle of molecular events in which thick myosin filaments repeatedly attach to and pull on thin actin filaments, so they slide over one another. The actin filaments are attached to Z discs, each of which marks the end of a sarcomere. Web13 apr. 2024 · Vortex math is a system of numbers which explains the essence of form as a sphere with a vortex. The numbers reveal a spiral line and a curved plane. The numbers in this spiral line describe the form of a vortex , the vortex describes an inward contraction with its equal expansion which is the inner form of a torus .
Web13 aug. 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. Web22 sep. 2024 · It can be seen that the part displacement distribution in three directions is significantly different. In regard to the displacement along the X direction, as shown in Fig. 4a, the thin-walled part has a large inward contraction at the middle of the part while a small inward contraction at the bottom and top of the part.
