What is the difference between Morula , blastula and blastocyst?
What is the difference between Morula , blastula and blastocyst?
Both the morula and blastocyst refer to the earliest stages of an embryo. After 3–4 days of the egg being inseminated the embryo cells assume a spherical shape. This transition is known as the morula.
After 4–5 days, a cavity forms within the embryo cells. This stage is known as the blastocyst. Further, cells within the blastocyst are known as the inner cell mass and is the initial stage in giving rise to the head and body of the developing fetus.
The blastula is the phase that comes after the morula (solid ball phase), but before the blastocyst. It is a group of cells arranged in a hollow sphere, containing fluid.
A blastula, in general, is a spherical mass of cells surrounding a fluid formed after fertilization.
In mammals, the blastula forms the blastocyst in the next stage of development. Here the cells in the blastula arrange themselves in two layers: the inner cell mass and an outer layer called the trophoblast. The inner cell mass is also known as the embryoblast; this mass of cells will go on to form the embryo.
