Hello, In our twenty-first class of the Cell Biology course for higher education, we will discuss the cytoskeleton, with an emphasis on microfilaments (actin filaments)! Don't know what it's about? Come with me, it's a hit! The cytoskeleton establishes, modifies and maintains the shape of cells. It is responsible for cell movements and the movement of organelles, chromosomes, vesicles and various granules. Its main components are microtubules, actin filaments and intermediate filaments. Motor proteins play an important role, crucially helping microtubules and actin microfilaments in cell movements and in the movement of particles within cells. Microfilaments or actin filaments are solid fibers formed by two intertwined strands of actin molecules, which is also a globular protein. They are related to maintaining cell shape, muscle contraction and cell motility, which ensures amoeboid movement. #CellBiology #Microfilaments #Cytoskeleton
