What is the Morula?
Morula is one of the earliest stages in embryonic development, occurring in front of the embryo implant, but after it is fertilized. This phase is usually achieved about four to five days after fertilization, followed by the development of blastula, a cluster of cells surrounding the cavity filled with liquid. Morula is an important state of development and can be easily identified on a high -performance microscope used to monitor embryonic development.
embryonic development begins with fertilization to create a zygot. Zygota begins to replicate and divide, still remains within the limits of Zona Pellucida, a membrane that surrounds the outside of the egg. When approximately 12 to 30 cells developed, the growing embryo becomes the switch. The cells have a slightly blurred appearance and look as if they were running together. They are also very small because they are still inside Zona Pellucida. Thus, the number of cells increases, but the total size remains the same.
Once in the Morula phase, cells begin to distinguish and arrange into the shape of blastula. It also indicatesThe beginning of the Zona Pellucida Disintegration, which allows the embryo to grow and combine the embryo with the uterus wall so that the placenta can develop. These are all critical monuments in embryonic development, and every landmark also represents a phase where development can go wrong or stop, sometimes without apparent cause.
Looking at enlargement, this tight ball of cells resembles the fruit of the mulberry tree. This is referred to in the name "Morula", "Latin for" Mulberry ". The number of participating cells may change because as cells begin to divide, they can divide at different speeds. The development of embryos does not follow the exponential progression of two, four, eight, 16 and 32 cells, in other words; At any time, the time of the cells in the embryo may vary.
When people are treated in vitro by fertilization of infertility problems, they strive for the transmission of embryos after the Stage of Morolu so that they can implant into the uterus. If the evolving embryo afterFive days still switch, it raises concerns that it does not have to further develop and is no longer viable, although it can be absolutely healthy and just a little slower than usual. Some doctors like to wait until they are convinced that cellular division and development are still occurring, while others can continue and transfer the planger.
