And you do this a number of times, dividing from two cells to four, and from four cells to eight, all the while staying within the zona pellucida.The rapid, multiple rounds of cell division are termed cleavage. Cleavage is illustrated in (Figure 1a). After the cleavage has produced over 100 cells, the embryo is called a blastula.

Since cleavage is impeded by the vegetal pole, there is a very uneven distribution and size of cells. Cells are more numerous and smaller at the animal pole of the zygote than at the vegetal pole. In holoblastic eggs, the first cleavage always occurs along the vegetal-animal axis of the egg, and the second cleavage is perpendicular to the first.Cleavage is the process after fertilization when early rapid mitotic cell divisions occur without growth (progressively reduce cell size because the total embryonic mass remains constant).

A cleavage furrow is an indentation that appears in a cell’s surface when the cell is preparing to divide. It marks the beginning of the cell’s “pinching” its cell membrane and cytoplasm down the middle. Eventually, the cell will pinch itself completely in two, forming two daughter cells.A woman's cleavage. Cleavage is the narrow depression or hollow between the breasts of a woman.
