This fissure or âcrackâ is called the cleavage furrow. The furrow deepens as the actin ring contracts; eventually the membrane is cleaved in two. Cytokinesis: During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate.
A ring of protein filaments called the contractile ring forms around the equator of the cell just beneath the plasma membrane. The contractile ring shrinks at the equator of the cell, pinching the plasma membrane inward, and forming what is called a cleavage furrow.Eventually, the contractile ring shrinks to the point that there are two separate cells each bound by its own plasma membrane.Further Exploration. ring of protein filaments called the contractile ring forms around the equator of the cell just beneath the plasma membrane.
