PATHOLOGY

Detailed explanation-1: -In many animal cells, actomyosin filaments assemble at the cleavage furrow, often forming an annular structure known as the “contractile ring” (Fig.

Detailed explanation-2: -Cytokinesis in animal and plant cells. In an animal cell, a contractile ring of cytoskeletal fibers forms at the middle of the cell and contracts inward, producing an indentation called the cleavage furrow. Eventually, the contractile ring pinches the mother cell in two, producing two daughter cells.

Detailed explanation-3: -During cytokinesis, the cell membrane pinches in at the cell equator, forming a cleft called the cleavage furrow.

Detailed explanation-4: -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-5: -Animal cell cleavage furrow formation is caused by a ring of actin microfilaments called the contractile ring, which forms during early anaphase. Myosin is present in the region of the contractile ring as concentrated microfilaments and actin filaments are predominant in this region.
