1.1 Describe, in-depth, stages of development from conception to birth in groups of 4 weeks i.e. 0-4, 4-8, 8-12...36-40 weeks. Even before women know they’re pregnant important changes are already happening in their bodies. The first week of conception the zygote this is when the egg and sperm join it now has divided into many cells. Within two weeks the embryo will attach to the woman’s uterine wall. The embryo will continue to grow climaxing with the baby’s birth. 0-4 weeks You begin life as a single cell, formed when the sperm fertilises the egg. Out of all the sperm it only takes one sperm and one egg to fertilise at conception. This is called fertilization; which takes place in the Fallopian tube, the fertilized egg then divides

    This chapter talks about the development of children. It starts out talking about how in just 2 year a child goes from being helpless, little, and not really doing anything. To running, jumping, talking, playing, hugging, and kissing. In just 2 years a helpless baby becomes a human. The brain is the thing that controls the whole body from making a childes hands work to making them grow in size. The head of the child develops more quickly than the rest of the body. After 8 weeks of conception the head of the baby makes up half of its length. The brine develops more quickly than that the spinal cord. As the child grows in size they also grow in the ability to pick things up, and to move. The most dramatic weight and high change happens while the kid is in

    Isn 't it crazy to think that we were once just a tiny organism? Nothing more than a group cells forming together? From the time of conception, the baby develops so quickly it is remarkable. The period from conception to birth is a truly beautiful development. And while the baby is quickly being formed from cell to human, the parents are quickly learning the birthing process and all there is to expect. There are three major parts to having a baby, the prenatal development, birth and the postpartum period.

    A fertilized egg cell, zygote, is produced when two gamete cells, male and female gamete, fuse by sexual reproduction. After sexual reproduction, a single sperm cell can live between 48-72 hours. The sperm cells begin to swim towards the fallopian tubes to fertilize the egg cell waiting in the fallopian tube. Fertilization takes around 24hours; once the sperm cell penetrates the oocyte it leaves the plasma behind and the egg cell changes its surface so that another sperm cell cannot penetrate the egg cell. After the sperm cell entering the egg it finishes it second meiotic division, which forms an ovum and a second polar body. Within 24-48 hours after fertilization early signs of pregnancy can be detected. (Chronolab)

    The initial product of the union of ovum and sperm; a fertilized ovum, is called the zygote. It begins as a single cell and rapidly divides to become a blastocyst or the development stage of the zygote when it is about 5 days old and ready for implantation; the embedding of the blastocyst in the inner uterine wall.

    There are two different ways to break down the prenatal time period: by trimester or by periods. The first period is called the germinal period. This time frame consists of the first fourteen days of the baby’s development starting with conception. During these two weeks, the fertilized egg makes it’s way into the uterus for implantation in the lining of the uterus. The next period, the embryonic period starts here. The embryonic period lasts the third through the eighth week of pregnancy. During this time period, according to Kathleen Stassen Burger, Author of The Developing Person: Through Childhood and Adolescence, “…the formless mass of cells becomes a distinct being-not yet recognizably human, but worthy of a new name, embryo” (Burg...

    This is the embryonic period, which occurs three weeks after conception and lasts until the eighth week. During the fourth week, the shape of the head begins to form, along with the formation of the eyes, mouth, nose, and mouth. Through the fifth and eighth week the lower body develops, as the legs and arms appear. After the embryonic stage, the fetal stage begins, which is during the ninth week through birth, where the fetus has a physical appearance distinctive to human features compared to when it was an embryo. At birth, one of the earliest signs of motor development is its first reflexes as a newborn coming out the mother’s womb. Newborns reflexes are not learned, rather they are born with these reflexes and act instinctively to protect itself in its first few months of life. At this point both the physical and motor development is starting to develop naturally at the same

    When an egg and sperm meet this process is known as fertilization. The zygote will begin the process of dividing into cells, eventually becoming a baby. When the zygote process of dividing does not work, “twins and multiples are sometimes the result.” There are identical twins and fraternal twins. When one egg is fertilized the babies will be identical. However, when two eggs are fertilized the babies will be fraternal. When the cells do not split apart the twins will be conjoined. (Ciccarelli & White, 2015).

    Fertilization occurs when the sperm from the male and the ovum from the female combine to create a zygote. The zygote will then go through a gestational period which consists of three different stages. The first stage is the germinal stage and it starts from conception and ends at two weeks, during this stage the zygote divides and becomes much more complex and then implants into the uterine wall where it will then go on to the second stage. The second stage is the embryonic stage, this stage starts at two weeks and ends at eight weeks. During the embryonic stage the zygote has become an embryo and the organs and major body systems form and develop very rapidly. This is one of the most critical periods for physical development, the embryo is very sensitive to many different types of influences. The third and final stage of the gestational period is the fetal stage, this stage starts at eight weeks and ends at birth. During this stage the fetus grows approximately twenty times its previous length and the organs and body systems continue to develop becoming more complex and becomes ready for survival outside of the womb. Children grow the fastest during the first three years of their life, and they will never grow this rapidly again. As the child grows the child will go through various stages of physical development such as puberty and sexual maturity. After the first few
