THE DEVELOPMENT OF HAILEY
Human Growth and Development
Have you ever wondered all of the developmental stages a child can make? It all starts right at the time of conception. There is so much more to a life than anyone realizes. The first three years of life is a period of incredible growth in all areas of a baby's development. Human's all have one thing in common, we all go through physical, cognitive, and psychosocial development. I am going to explain the first three years of life to you, by using someone very close to me, my daughter Hailey.
The fetal stage, also known as prenatal development, is a stage of life that so much can occur. Humans begin life as a single cell. There are multiple stages that have to happen in order to become a "human." The first stage is known as the Germinal Stage. The Germinal Stage is from the conception to implantation which is from 0 to 2 weeks. This is the period when cell division occurs, the zygote reaches the uterus and begins to implant on the uterine wall. The process of implantation can take up to a week. Our next stage is the Embryonic Stage. This stage is from implantation till the end of the first two months. Some of the things that occur in this stage are, vital organs and bodily systems begin to develop from the embryonic disk. The nervous system, sensory organs, hair, outer skin, digestive and respiratory systems, liver and pancreas, bones, and muscles are all beginning to develop. At 7 weeks genetic activity on the Y chromosome causes testes to differtiate, meaning if there is no Y chromosome then ovaries will differentiate. Stage 3 is the fetal stage, which is from the third month until birth. There is so much that happens during this time. By the end of the second trimester I felt fetal movement, the eyes begin opening and closing, thumb sucking, and the pattern of sleep begins. By the end of the third trimester, the fetus typically weighing 6-7lbs and around 20in long. The survival rate increases to...
