One day before conception the woman ovulates and produces one mature ovum. During the conception process one sperm out of millions by the man may penetrate the outside layer of the ovum and fertilize it. The start of pregnancy is about 10 days after conception. 14 days after conception it has now developed into the fetus central nervous system. Its heart begins to beat and at this time the woman might have noticed that her menstrual period is late.
CONCEPTION PHYSICAL Conception is the beginning of human development and happens when the sperm meets an egg. In the first month, the first two weeks will be the embryo attaching itself to the uterine wall. After 25 days, the baby’s body will start to develop (only the head, followed by the trunk and arm buds). The heart will also start beating. By 30 days, the baby will be a quarter of an inch long.
It is the physical condition in which a woman’s body is nurturing a developing embryo or foetus. STAGES OF PRENATAL DEVELOPMENT. Germinal stage This stage covers two weeks after fertilization. The zygote undergoes rapid cell division then migrates slowly down the mother’s fallopian tube and is implanted in the uterine wall. The placenta begins to form enabling the developing zygote to attach itself to the mother’s uterine wall.
Physical Development Physical development includes motor skills, co-ordination and the influence of hormones. Infancy ( 0-3) Human development begins after the union of male and female gametes or germ cells during a process known as fertilization (conception). When this happens only half of the fertilised eggs become babies. 3 days after fertilisation the egg is the size of a pin head and becomes embedded in the uterus. Labour begins when a women’s water break, this is the amniotic fluid that protects the baby.
In our world, everyone will be born a baby, a pure and innocent being. However, like everyone else, babies are fated to grow up, no one can escape the inevitability of the human life cycle. Soon, the infant will turn into the meddling, troublesome toddler, from crying at all hours of the day and night, to drawing on the walls with crayon. From toddler he/she will morph into a big kid, in which is almost the same as a toddler, but this time the child will know how to use some things the proper way. This is the age where the child starts to make friends in school.
Rudolfe Schaffer and Peggy Emerson (1964) studied sixty babies at monthly intervals for the first eighteen months of life; and a regular pattern was identified in the development of attachment (Hardy, S. 1995). They discovered that attachment developed in the following sequence:- Birth to six months - this is the indiscriminate attachment phase, the newborn is predisposed to attach to any human; most babies respond equally to any caregiver. After four months - preference for certain people; infants learn to distinguish primary and secondary caregivers, but still except care from anyone. After seven months - special preference for a single attachment figure; the baby looks to particular people for security and comfort; they show fear of strangers and unhappiness when separated from a special person. After nine months – multiple attachment; the baby becomes increasingly independent and forms several attachments.
Embryonic Stem Cell Research A stem cell is a type of cell that can give rise to more cells of its kind, with at least one type of specialized cell. Human bodies possess different kinds of stem cells in different stages of life, and embryonic stem cells exist only in the first few weeks of human life, when humans are embryos. Embryos are fertilized eggs formed when a human egg and sperm fuse together and begin to undergo cell division. After about five days from the first division embryos develop into a hollowed-out ball of fluid that contains around 150 cells called a blastocyst. A part of the blastocyst will become the placenta, which will serve to nurture the growing embryo.
Professional practice Introduction I am currently working in a newly built crèche, at the moment the crèche has 46 children in attendance on a daily basis. But has the capacity to hold 60 children every day. The crèche has specifically been built in sections (Appendix one). There are two rooms on the right for babies under 18 months old which caters for babies aged between 3 months to toddling and a room for babies toddling to 18 months, between these rooms there is a nappy changing area, a milk room for staff to make up bottles and snacks and also 2 cot rooms. On the right hand side we have three rooms for 32 children aged 18 months to 2 years, 2-3 years and 3-5 years.
The period immediate following conception is a critical period in a fetus’ life. This five-week interval is crucial to normal development. During this time the fetus’ organs are forming at different times. Most significant of all is the development of the nervous system, particularly the brain (Obstet, 2008). When an infant presents with an issue that was likely caused by environmental factors, ie; smoking, and pesticides use, it is possible to trace back the time when the baby may have been exposed to the substance (Obstet, 2008).
He further explained that when the brain operates, all other properties essential for being human are already acquired. Therefore, it can be deduced that the main required property of being a human is having a functioning brain. Finally, as there are progressive stages in the physical development and function of the brain, the fetal brain can only support spontaneous motion in the third month after conception. Brody
