May 20, 2024 · The first stage, known as the germinal stage, involves the formation of the zygote and early cell division. The second stage, called the embryonic stage, involves the early growth of the embryo, including the formation of the neural tube, which will eventually become the brain and spinal cord.
The germinal stage lasts a total of eight to nine days. It begins in a Fallopian tube when an ovum is fertilized by a sperm to form a zygote (day 0). The germinal stage continues as the zygote undergoes several initial cell divisions to form a solid ball of cells called a morula (days 3-4).
Learn about the three stages of fetal development: germinal, embryonic and fetal. The germinal stage begins at conception and lasts until implantation, when the blastocyst becomes an embryo.
The germinal stage is the first two weeks of pregnancy, when the zygote forms, divides, and implants in the uterus. Learn about the key events and milestones of this stage and how they affect the developing embryo.
Learn how the developing baby changes from a one-cell zygote to a fetus in three stages: germinal, embryonic, and fetal. Each stage has distinct features, challenges, and milestones that affect the baby's growth and survival.
The germinal period is the first stage of prenatal development and occurs from the moment of conception until the end of the second week. During this time, the fertilized egg, or zygote, undergoes a rapid process of cell division, ultimately resulting in a hollow ball of cells called a blastocyst.
The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus. The germinal stage takes around 10 days. [1] During this stage, the zygote begins to divide, in a process called cleavage .
