The actin filaments are attached to Z discs, each of which marks the end of a sarcomere.

WebContraction of the external intercostal muscles moves the ribs upward and outward, causing the rib cage to expand, which increases the volume of the thoracic cavity. Due to … WebThese gradients cause currents to flow, which generate the EKG signals we can record from our electrodes. So, repolarization is actually contraction of the muscle cells of the heart, which creates the characteristic shape of the T wave on an electrocardiogram. The direction of this process is inward (contracting) during phase 1 and outward ...

Hugo Gonzales-Serratos (d. 2011) came to Andrew Huxley’s laboratory from Mexico in the early 1960s to work for a Ph.D. He devised a remarkable experiment to determine the velocity of inward spread of contraction in a single frog muscle fiber.
WebMitosis in Animals (Source: KhanAcamedy) In animal cells, mitosis is characterized by the inward contraction of the cytoskeletal fibers and the pinching of the cell in a process called contractile cytokinesis. This inward contraction then produces a depression known as the cleavage furrow.
