| This video performs you the process of a fertilized egg to a baby in 3D!! You'll find the magnificent work of our Creator... Explanations: After sexual intercourse, sperm travels through the cervix and uterus and into the Fallopian tubes. Conception usually takes place in the outer third of the Fallopian tube. A single sperm penetrates that egg and a joining of the genetic information occurs. This resulting single cell is called a zygote. The zygote spends the next few days traveling down the Fallopian tube and rapidly multiplying the number of cells through division. A mulberry-like mass, like a hollow rubber ball, 1/100 inch wide, results from the cell division. This ball of cells in the Fallopian tube is called a morula. The embryonic stage begins on the 15th day after conception and continues until about the 8th week, or until the embryo is 1.2 inches in length. Week 3 we see the formation of the heart, the beginning development of the brain and spinal cord, and the beginning of the gastrointestinal tract. Weeks 4 and 5 -1/4 inch long: Here we see the beginnings of the vertebra, the lower jaw, the larynx ("voice box"), and the rudiments of the ear and eye. The heart, which is still outside body, now beats at a regular rhythm. Although arm and leg "buds" are visible with hand and foot "pads," the embryo still has a tail and cannot be distinguished from pig, rabbit, elephant, or chick embryo by an untrained eye. Week 6 - 1/2 inch, 1/1000 of an ounce: In week 6, we see ... |
