An <actomyosin ring> is a contractile assembly containing <actin> filaments and <myosin II>. In typical <animal> <cytokinesis>, it forms in the <cell cortex> beneath the <cell membrane>. Its contraction draws the boundary inward to produce a <cleavage furrow>; an inward groove is not yet complete separation of the daughters.<The Cell: A Molecular Approach, 2nd edition by Geoffrey M.
