Morula Development - Embryology
(Latin, morula = mulberry) An early stage in post-fertilization development when cells have rapidly mitotically divided to produce a solid mass of cells (12-15 cells) with a "mulberry" appearance. This stage is followed by formation of a cavity in this cellular mass blastocyst stage.
Cleavage (embryo) - Wikipedia
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.
Morula | Description & Facts | Britannica
morula, solid mass of blastomeres resulting from a number of cleavages of a zygote, or fertilized egg. Its name derives from its resemblance to a mulberry (Latin: morum). A morula is usually produced in those species the eggs of which contain little yolk and, consequently, undergo complete cleavage.
Morula - Meaning, Stage and Transformation of Morula into ...
Morula is the combined solid mass of cells, which are known as blastomeres, formed by the cleavage of the single-cell zygote which in turn is formed after fertilization of the ovum by the sperm. On the other hand, a blastula is a ball of cells consisting of two layers that are formed by the dynamic arrangement of the blastomeres.
Morula- Stage, Development, Significance - Microbe Notes
2023年8月3日 · The morula is the first embryonic stage where mammalian cells can be categorized as being either internal or external. The morula reaches the uterus between three and four days of development and greatly absorbs nutrients and fluid from the surrounding in preparation for the implantation process.
Morula - Cellular Development, Function & Anatomy - LifeMap ...
The morula is a globular solid mass of 16-32 blastomeres formed by cleavage of the zygote that precedes the blastocyst. A process named compaction begins at the 8-cell stage, wherein the round and loosely connected blastomeres assume a flattened polarized cell morphology.
