Let me tell you about the science behind the birds and the bees. In this paper the author will explore the physical growth a fetus from conception to birth. An individual experiences three different stages while inside a mother’s womb; Germinal, Embryonic, and Fetal periods when the most extreme changes occur. Germinal Stage
The germinal stage of development starts with the fertilization and lasts about fourteen days. Fertilization occurs when a male’s sperm make the successful trip through the fallopian tubes and fuse with the female egg. The baby’s genes and sex are determined at this instant. It is difficult to pinpoint the exact day of conception, so the doctor will begin counting the pregnancy from the first day of the mothers last menstrual period. The zygote can then travel toward the uterus, a voyage that can take up seven whole days to finish. Within the next twenty-four to thirty-six hours the cells will begin to divide and grow. The mass of cell

From day twenty-four to day fifty-six the cell mass is called an embryo in this stage and begins to take the form of a human. The embryo is divided into three layers which each will form an integral body systems. At approximately twenty-two days after conception, the neural tube forms giving that will develop into the central nervous system including the spinal cord and brain. Around the fourth week, the head, the eyes, nose, ears, and mouth begin to take shape. The cardiovascular system is where the earliest movement begins as primitive heart starts to pulse. During the fifth week small protrusions form that mark where the extremities will mature. By day fifty-fourth day of the pregnancy, the finger and toes are distinguishable. At the end of this stage near the eight week of development, the embryo will have all of the groundwork and basic organs excluding the of the sex organs. Eyes, knees and toes are all present on the soon to be
By day 22, the child’s heart begins to pump with their own blood. By week 5 the child’s eyes, legs, and hands begin to develop. By weeks 9 and 10 the baby is able to turn its head and frown. This article also shares with us that by the 20th week gestation, the baby can recognize its mother’s voice. And lastly it gives us the last steps before the baby is born; 7 to 9 months gestation is when the baby is using four of the five senses. He knows the difference between waking and sleeping and can relate to the moods of the
Conception is the action of conceiving a child or of a child being conceived. Every human being begins life as a single cell, formed when father's sperm fertilizes mother's egg. Fertilization normally takes place in the mother's Fallopian tube, which connects the uterus (womb) with the ovary. The uterus is the size and shape of a large pear: it is made of muscle and it stretches to allow the baby's growth throughout the months of pregnancy.
In the film, Life’s Greatest Miracle, takes us through the pattern of development. But where does it initially begin? From conception to birth there are many progressions. Initially it begins as two separate components a sperm and an egg. Once the sperm has completed its journey through the fallopian tubes and successfully entered the egg fertilization begins. Once fertilization is completed, the sperm and egg are one, and it is now embryo. During this time the embryo undergoes changes, body structures and internal organs develop. The head is the first develop, the growth starts near the center of the body. “At the beginning of this period, three layers form in the embryo.” These three layers are
After the first month the baby moves onto the second sub-stage which is primary circular reactions,and lasts until the baby is about four months old. During this stage the baby will repeat certain things that bring them pleasure and desired outcomes. Babies will begin to see that a pattern of events is connected and will begin to expect the second event after the first event has happened.
Based on my knowledge about prenatal development and childbirth I expected the women to answer the way they did. Development happens rapidly during the prenatal period, which is the time between conception and birth. Prenatal development is normally divided into three stages: the germinal stage, the embryonic stage, and the fetal stage.
...side begins to grow and develop at six weeks the baby is only five eights of an inch in measurement. As the months go on the baby goes thru many changes as well as the mother and her body. The mother may tend to get ill at times or may be fine during her pregnancy. There are also reports that the father may become ill at times as well along with the mother, this is common in men.
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.
Developmentally appropriate practice provides a framework of promoting quality in early childhood education programs. It Developmentally appropriate practice are used to help create a program that is acceptable for the age and development of young groups of children with also considering the individual need of each child. When programs use developmentally appropriate practice they should help develop the domains of development. These domains are all connected, a child’s development in one domain impacts what takes place in another domain.
The process of human development is very complex. It is a continual process, providing gradual development for the fetus. Some of the most important factors to fetal development such as blood flow, heart beats, muscle development, and brain activity can all be determined within the first seven weeks of pregnancy (Baby Developme...
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
Child development and growth observation can be quite fascinating considering the uniqueness of each child. As children grow, they normally develop and acquire new skills whether complex or not. The abilities experienced by each child progresses differently that is it depends on the nurturing given by the parent or guardian and on the characteristics that they inherit. Proper development and growth of the child occurs when basic needs are provided by the reliable adult guardians, including such things as love, food, encouragement, shelter and warmth. The essay evaluates child development and growth through observation conducted by myself on my nephew. The essay will include physical development, general health, emotional development,
This process is called conception, the female is now officially two weeks pregnant and the fertilized egg is called a zygote. Let’s move on to pregnancy. Pregnancy is a state in which a woman carries a fertilized egg inside her body, it usually lasts up to 40 weeks, and it is divided into three trimesters, each lasting three months. The first month. The embryo is about a third of an inch long. The head, trunk, and the beginnings of the arms and legs have started to develop. By this month, the embryo starts to receive nutrients and releases waste through the umbilical cord and placenta. The heart also starts to beat. The second month. The heart is now pumping and the nervous system, including the brain and the spinal cord begins to develop. The fetus is 1 in 2.5cm now and has developed cartilage skeleton. The arms, legs, facial features and other major organs begin to appear. The third month. The fetus has grown up to 4 in 10cm and weighs a little more than an ounce. The major blood vessels are almost completed and the face starts to show up more. The kidneys and the 4 chambers of the heart are now complete. The fourth month. The fetus is now 4 oz of 112g and can kick and swallow. The
The prenatal period takes place in the first two weeks of conception. Heredity and environmental influences (which are often negative) are also developed during this stage. At this stage the organism is more susceptible to these influences, than during any other period. Infancy is the next stage, various changes start to occur and attachments start to form. Coordination, sensory and motor skills start to develop, as well as the expression of feelings and emotions.
It takes at least 20 weeks for a child to fully develop inside the womb starting the day of conception. A full pregnancy lasts 42 weeks. During the first week
