Introduction Baby’s take an average of 38-40 weeks to fully develop and prepare for birth. This time period of approximately nine months is broken down into 3 periods in which the baby spends growing from a tiny mass of cells into a functional, healthy, bouncing baby. If all goes smoothly the birth of a baby, including labor time could take between 4-8 hours, sometimes more, sometimes less. There are many factors that can affect the baby’s growth and development, called teratogens, but overall baby will slowly grow and develop until he or she is prepared to enter into the world. From the moment of conception the baby begins to develop for the remaining nine months.
This process will occur in states and can be monitored throughout each week of pregnancy. Through a process called differentiation, the embryo rapidly grows and takes on its main external features. Though some doctors and mothers count the pregnancy by weeks, for this paper it will be grouped into months. Pregnancy consists of a nine month incubation period inside the womb. Each month has their ... ... middle of paper ... ...ywhere from ten minutes to forty-eight hours.
When do the most important parts of the fetus form? The first days and weeks after conception are critical for fetus body formation. The most extensive transformation of life occurs before birth. The fetal period goes through major changes. During the third month male or female sexual organs begin to develop and is visible through ultrasound.
The beginning of the third week after conception marks the start of the embryonic period, a time when the mass of cells becomes a distinct human being. The embryo begins to divide into three layers each of which will become an important body system (Cherry, 2015). Approximately 22 days after conception, the neural tube forms. Cherry (2015) argues that this tube will later develop into the central nervous system including the spinal cord and brain. Around the fourth week, the head starts to form quickly followed by the eyes, nose, ears, and mouth.
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. Typical prenatal development takes around 38-40 weeks. There are three major periods of prenatal development. The stages are the germinal period, the embryonic period, and the fetal period.
More specifically, the zygotes are the first cell organism’s that are produced. The embryo is a cell before it completes fertilization and becomes a fetus. And the fetus is an embryo at a more advanced stage of development. I’ve learned that by 6 month’s it is possible for the baby to survive if born prematurely. During pregnancy it is very important to pay c...
Around this time the ultrasound can pick up what gender the developing fetus will be. During this time the fetus is at risk during this highly critical period for developing masculinization of female genitalia and mental retardation. Around five months the brain increases in size and the heartbeat gets stronger. During the last month there is the most crucial brain development, which leads to the complex make up we contain. Fingernails, eyelashes and toenails tend to start growing.
Introduction This paper is used to gain a better understanding of premature births and the causes of pre-term birth in relation to genetics and environmental effects. Also, it will look into what premature birth means for the growth and development of the effected child throughout his/her life. A normal human gestation period is about 40 weeks from the start of the last menstrual period until childbirth. Any labor that begins before 37 weeks of pregnancy is considered preterm labor. Preterm birth is the leading cause of infant death and long-term difficulties such as neurological damage and disabilities in children.
Thinking about human development the first thing that pops into my mind would have to be fetal development. Not only is it the first stage of life, but it is also the most critical. To understand how critical the development of a fetus is knowing what happens in every stage when the fetus is growing, and what can have an effect on the fetus or what could go wrong. In just 9 short months the fetus is full term and everything as pretty much developed, during the months in between a tremendous amount of growing is done. Of course the first part of this amazing cycle occurs with the zygote .
Then once they learn all of that, they have to learn to get along with their body again, because adolescence starts. They have to mature into a good adult. While still in the womb, a baby develops all the time. The first trimester is a busy time in the life of a child. During the first month the baby gains dark spots for the eyes and is as long a grain of rice.
