What are microfilaments?

microfilaments are found inside the cells and are small strands made of protein called actin. Sometimes they are referred to as actin fibers or thin fibers and help to support the structure of the cell or cytoskeleton. In addition, microfilaments are connected to a change in cell shape, cell movement and division. Inside the muscle, microfilaments are arranged together with strong fibers made of myosin protein and together allow muscle contraction to be muscular. They are contained in a substance that fills a cell known as cytoplasm. Each microfilament consists of many small molecules of protein called actin, which is produced inside the cell. Individual actin molecules are rounded and are trapped into long chains. Two long chains are circling around them to create a spiral known as a spiral, and this creates one microfilament with a diameter of about five nanometers. Here they can regulate the shape of the cell and respond to changes in the environment. Thin fibers play a role in creating small projections from cellulara surface known as microvilli. They can also create a larger protrusion, allowing the cell to move through a similar direction across the surface. Microfilaments also contribute to the expansion of the surfaces of some immune cells to absorb undesirable substances.

inside the muscle, actin fibers combine with myosin fibers in a way that gives the muscles their strength and the ability to download. Myosin fibers are connected together to form so -called thick fibers, with a diameter of about 15 nanometers. Stacks of dense fibers and piles of thin fibers are arranged alternately along length muscle fiber, with their ends slightly overlapping. During muscle contractions, and broken bonds between thin and thick fibers are formed and caused by the fibers to slide around the other in the movement of a similar blow.

Given that eukaryotic cells in animals rely on microfilaments to function normally, nOther fungi and plants produce poisons to focus them as protection against consumption. Many toxins in such poisons work by tying actin molecules, disrupting the production and behavior of microfilaments. One example is the poison of Phalloidin, which is found in the fungi of deaths, and it has been proposed that the consumption of large amounts of raw meat can help against the effect of this toxin by providing a lot of extra actual for phalloidin to tie.
