The contractile ring consists mainly of actin filaments and myosin filaments. It is found arranged in a ring around the equator of the cell and plays a key role during cytokinesis. Towards the end of mitosis, it starts to assemble just beneath the plasma membrane. As the ring contracts, it pulls the membrane inward; dividing the cell in two[1].
