Detailed explanation-1: -Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells. It occurs concurrently with two types of nuclear division called mitosis and meiosis, which occur in animal cells.

Detailed explanation-2: -In animal cells, the area of the cell membrane that pinches inward to separate the dividing cell into two cells is called the cleavage furrow.

Detailed explanation-3: -In animals, cell division occurs when a band of cytoskeletal fibers called the contractile ring contracts inward and pinches the cell in two, a process called contractile cytokinesis.

Detailed explanation-4: -During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.

Detailed explanation-5: -The cytoplasm of the cell is being divided in order to obtain two new daughter cells. How does cytokinesis occur? Cytokinesis occurs in mammalian cell division when a contractile ring of microfilaments generates a cleavage furrow that pinches the cell membrane in two.
