Explanation:
Detailed explanation-1: -Microfilaments assist with cell movement and are made of a protein called actin. Actin works with another protein called myosin to produce muscle movements, cell division, and cytoplasmic streaming. Microfilaments keep organelles in place within the cell.
Detailed explanation-2: -Microfilaments are solid rods made of a protein known as actin. When it is first produced by the cell, actin appears in a globular form (G-actin; see Figure 1).
Detailed explanation-3: -Two classes of actin microfilaments are associated with the inner cytoskeleton of axons.
