Milestones Of Prenatal Development

At one month of pregnancy the baby is still any embryo and it is made up of two layers which will soon produce into body parts and organs. In the first two weeks of pregnancy a women isn’t actually pregnant because the women’s body is preparing for ovulation as usual. You usually ovulate (release an egg) around two weeks after the first day of your period this depends on the length of your period. Then during the third week after the first day of your last period your fertilised egg moves across the fallopian tube towards the womb. The egg starts off as a single cell but it divides multiple times. By the time the egg reaches the womb it becomes the mass of 100 cells which is known as an embryo. In the fourth week of pregnancy the embryo grows and develops in the lining of the womb. The outer cells reach out and link themselves with the mothers blood supply. The inner cells form

S: Page 134 is all about the embryonic period of pregnancy. The embryonic period lasts from week 3 to week 8, and it is a very important time because that is when the ectoderm, mesoderm, and endoderm are being formed. The ectoderm, mesoderm, and endoderm will later for more important oragans and body structures.

When an embryo becomes a fetus at eight weeks, it is approximately 3 centimeters; by the time the fetus is considered full-term, he or she may be 50 centimeters (Brisbane 60). The fetal stage, that takes place during week 9 to birth, result in a whole bunch of changes. (Brisbane 61). During the fetal stage, all parts of the body mature, and the overall of the baby size increases. Although all of the organ systems were formed during embryonic development, they continue to develop and grow during the fetal stage as well. During the third month, the reproductive system becomes developed and the sex of the baby becomes apparent (Staff). For girls, the ovarian follicles begin to form and for boys the prostate gland. Throughout months four through six, the heartbeat grows stronger and other body systems become further developed (Brisbane 63). Features such as fingernails, hair, eyelashes and toenails form. During the period from seven months until birth, the fetus continues to develop, put on weight, and prepare for life outside the womb (Brisbane 64). The lungs begin to expand and contract, preparing the muscles for breathing (Brisbane 64). The time in which the baby is born is a very critical. In some situations, a baby can be born as early as 7 months. When a baby is born too early, his ar her organs are not usually fully formed. This can result in many complications and health problems. Including, If premature pregnancy is the case, the baby would need some intensive care in hospitals. If the baby survives the stages, at the end of the nine month of pregnancy the baby will turn to a head-down position to prepare for birth. If the baby is not in the head-down position and in breech position a cesarean section may be required, which can cause many more complications. If a baby passes all these crucial factors, it is guaranteed to be born

It is imperative for a mother to take care of herself while pregnant. This will give the fetus a better chance at healthy developmental milestones. One way to achieve this is through a healthy diet which aids fetal brain development. Moreover, taking the supplemental vitamins recommended by the physician helps too. Finally, a mother should try to eliminate too much stress in her life while pregnant. This can have a negative impact on the pregnancy. This is what healthy development looks like during conception. At 3 months the baby is fully formed. The hands, arms, feet and toes are all present. Also, the bodily organs are present but need to mature more at this point. During the 3-6 month period is where the most rapid brain development takes place (Hutchison, 2013). This is the trimester where you begin to feel movement. At 6-9 months the baby continues to grow and mature to prepare for entry into the world.

Prenatal development is the process of rapid growth and change of a zygote to a fully formed baby that begins about 40 weeks prior to birth. It is divided into three trimesters where the first ends at the end of the embryonic stage, the second around the 20th week of pregnancy, and the third ends at birth. These trimesters do not correspond with the three stages of prenatal development known as germinal, embryonic, and fetal.

Those stages are the Germinal stage, the Embryonic stage, and the Fetal stage. The Germinal Stage is the first stage and it is a two-week period that happens after the sperm and egg cell join together to form a zygote. This process is called conception. After conception, the zygote begins to divide. This turns into into a ball of cells that moves beside the fallopian tube. This travels all the way to the uterus. This process is called implantation and it happens when the cells is placed in the wall of the uterus. This process takes about a week to complete. After the two weeks, the Embryonic stage takes place next. The embryonic stage takes two to eight weeks right after conception. At this point in the process, the ball of cells is now an embryo. In this stage, all the major organs form. The last stage of prenatal development is the Fetal stage. This last eight weeks after conception up to birth. One of the first things to take place is the sex organs begin to form. Next, the bones form, muscles form, and the fetus begins to move. The organ systems also begin to develop and the brain’s size grows. One of the last things to work independently is the respiratory and digestive

After implanted into the mother’s uterus, “All of the essential structures have been formed (both inside and outside) by the time the embryonic period comes to an end. The new title of fetus is now given to the embryo” (Roundy, 2014). Essentially, the mass of cells is now known as an embryo and the eyes, head, mouth and nose start to take shape. Blood vessels surround the embryo, leading to a very own heartbeat. The formation of upper extremities and lower extremities are developing! The sex of the baby will be determined, whether the baby will be a boy or baby girl.

The first trimester consists of all embryonic development and the primary month of fetal development. By the end of the third month (end of 1st trimester), the cartilage skeleton is beginning to ossify, the kidneys as well as liver are operating, teeth have formed, and determination of whether male or female can be concluded. In contrast, in the third trimester they eyes open and shut, the sucking reply evolves (numerous fetuses initiate to suck their thumbs or other fingers), and loud noses begin a startle response. The lanugo is vanished, and a layer of protective fat initiates to develop.

Due to modern medicine, there are many ways that pregnant women can now see how their fetus is growing inside them. The woman’s egg travels down the fallopian tube entering the uterus. It is fertilized by the sperm and its home for the next nine months. There is a long process before the baby arrives into the mother's arms. This is the beginning of conception and the development of the baby.

Babies have an active in-utero brain development. The growth rate of a human baby is probably the fastest during the 9 months of pregnancy, the little one’s pre-brain makes out more than 8000 cells per second, it pumps out neurons at the rate of approximately 500,000 cells a minute. To ensure the proper neural development at this stage, it is crucial to leave the baby alone. During the first half of the pregnancy, the baby grows its neurological structure at an astonishing rate. Through a process called Synaptogenesis, the baby brain makes over 15,000 neural connections and continues to grow. During the second half of pregnancy, the fetus starts to grow sensitivity of the world through his semi-developed neural connections. It is at this stage that they become subject to external influences - they react to sounds and feel the touch. Medina even cited examples where kids could actually remember their in-utero experiences long after their birth.

A very crucial period during pregnancy is the embryonic period of development spans from week 3 through week 8 of the pregnancy. It is during this first trimester that a mother should protect its womb and consume no alcohol. Also, during these weeks of pregnancy, “all of the baby’s organs begin to develop and function at a basic level. The developing baby undergoes very, very rapid cell differentiation during this time” (Welch, 2016).The beginning features of its eyes and ears start to develop. The heart is beating and tiny limb buds, which develop into arms and legs, appear. The central nervous system (the brain and spinal column) start forming as well. Essentially, the most dramatic changes of prenatal development occur during the first

During the first two weeks, the mother is not even pregnant yet. Week 1 is the first week of her menstrual cycle; and during the second week, the ovary releases an egg to flow into the fallopian tube. At this point, the mother can become pregnant and if a sperm makes it to the egg in the fallopian tube, conception begins. At this point, it is called a zygote and has half of its DNA from each parent. During week 3, the zygote makes its

Important stages of pregnancy: Pregnancy is counted from the first day of the mother 's last period. Important development immediately takes place after fertilisation of egg and sperm cells. It divides into many cells in the first week, which forms a zygote made out of 100 to 150 cells that are already differentiating. In the second week, the zygote is then changed to an embryo and it sticks to the uterine wall. This process takes up to nine months to form and develop a baby.

An ectopic pregnancy occurs when the fertilized egg attaches itself to a place other than the inside of the uterus. The implantation can occur in various places such as on the surface of the ovary, in the cervix, in the abdomen or most commonly in the fallopian tubes. In most cases, ectopic pregnancies occur in the fallopian tube, which are not designed to hold a growing embryo. Generally, fertilization occurs at the usual distal third of the fallopian tube. After the union, zygote begins to divide and grow. However, due to an obstruction by several factors, the zygote cannot travel through the length of the tube. It lodges on that constricted part and implantation takes place at that area instead of the uterus (Taran, Kagan, Hübner, Hoopmann,

The fetal stage is the stage in which is marked by rapid growth and preparation
