PATHOLOGY

Detailed explanation-1: -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. The indentation produced as the ring contracts inward is called the cleavage furrow.

Detailed explanation-2: -Cytokinesis is the physical process that finally splits the parent cell into two identical daughter cells. During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.

Detailed explanation-3: -During cytokinesis, the cytoplasm splits in two and the cell divides. The process is different in plant and animal cells, as you can see in Figure 7.3. 8. In animal cells, the plasma membrane of the parent cell pinches inward along the cell’s equator until two daughter cells form.

Detailed explanation-4: -Cytokinesis is the second part of the mitotic phase during which cell division is completed by the physical separation of the cytoplasmic components into two daughter cells.

Detailed explanation-5: -Cytokinesis in Animal Cells Because of this, animal cells can bend their cell membrane inward and perform cytokinesis “from the outside in” by forming a cleavage furrow. A cleavage furrow is an indentation on the cell surface that continuously deepens until the animal cell is “pinched” into two separate halves.
