GENERAL HISTOLOGY

Detailed explanation-1: -Microfilament functions include cytokinesis, amoeboid movement, cell motility, changes in cell shape, endocytosis and exocytosis, cell contractility, and mechanical stability.

Detailed explanation-2: -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-3: -Functions of Microfilaments Actin is an indispensable protein for muscle movement, and microfilaments are often called actin filaments because actin is so prominent in the muscular system of the body. In muscle cells, actin works together with the protein myosin to allow the muscles to contract and relax.

Detailed explanation-4: -The microfilaments aid in mitotic division by relaxing and contracting to ‘pinch’ the parent cell in the middle until division occurs.

Detailed explanation-5: -Final answer: Microfilaments are composed mainly of a protein called actin.
