Morula and blastocyst

WebAsked By : Misty Matusz. A morula is distinct from a blastocyst in that a morula (3–4 days after fertilization) is a mass of 16 totipotent cells in a spherical shape whereas a … WebThe morula cells started to differentiate, and we developed trophoblasts on the outside and embryoblasts in the middle. We formed a little cavity and became known as a blastocyst. After the blastocyst cavity formed, or the blastocoel, a second cavity called the amniotic cavity formed, and a pancake of cells across the sphere became apparent.

The blastocyst stage occurs between 5 and 9 days after conception. During embryonic development, after fertilization (approximately 5–6 days in the human), the cells of the morula begin to undergo cell differentiation, and the morula changes into the blastocyst. In the uterus the zona pellucida surrounding the blastocyst breaks down, allowing it to implant into the uterine wall. Implantatio… In embryology, cleavage is the division of cells in the early development of the embryo, following fertilization. The zygotes of many species undergo rapid cell cycles with no significant overall 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, or of the blastocyst in mammals. WebAnswer: 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 blas...
