What is the name of the two poles created as a result of holoblastic cleavage?

Hand Pole and Mouth PoleIn embryology, cleavage is the division of cells in the early embryo. The zygotes of many species undergo rapid cell cycles with no significant growth, producing a cluster of cells the same size as the original zygote. The different cells derived from cleavage are called blastomeres and form a compact mass called the morula. Cleavage ends with the formation of the blastula.Depending mostly on the amount of yolk in the egg, the cleavage can be holoblastic (total or entire cleavage) or meroblastic (partial cleavage). The pole of the egg with the highest concentration of yolk is referred to as the vegetal pole while the opposite is referred to as the animal pole.


What is an animal pole?

An animal pole is the hemisphere of the blastula which eventually gives rise to the three germ layers.


What is the pattern of cleavage in amphibians?

In amphibians, the pattern of cleavage is typically holoblastic and unequal. This means that the entire egg undergoes cleavage, but the divisions are not equal; the animal pole (where the embryo will develop) divides more rapidly than the vegetal pole. The resulting cells, or blastomeres, vary in size, with smaller cells forming at the top and larger ones at the bottom. This unequal cleavage contributes to the organization and differentiation of the developing embryo.
