Recommended: Stages of development from conception to birth
Have you ever wondered how humans are developed? Have you ever wondered how our mere existence is developed in a nine month radius? From conception to birth the process that structures the human body is known as Prenatal Development. Prenatal Development is the time a child is conceived to the time it is born. Explaining the three stages of Prenatal Development will help the reader understand the importance of it. There are three stages of Prenatal Development. They include the germinal stage, the embryonic stage, and the fetal stage. The germinal stage is the first and the shortest stage. When the sperm from a man and the egg of a woman collide, they will create a union called the zygote. Over the next 36 hours, fertilization completes and becomes mitosis. This process is how the zygote travels through the fallopian tube toward the uterus. The process itself is longer than fertilization, timing over 3 to 4 days approximately. The zygote is now a blastocyst. This too will float around for about one or two days. The embryonic disk will form when the blastocyst sticks to one side o...
Pam Jenkins is a 36 year-old woman that is 30 weeks into her third pregnancy. Since her pregnancy began, Pam has gained 20 pounds. Although Pam has reduced the amount that she smokes, she continues to smoke 5 cigarettes per day, which may cause some issues with her worry of another preterm birth. Another factor that could also cause complications is her delayed prenatal vitamin use. After logging her dietary intake within a 24 hour period into SuperTracker, I will be making recommendations on how she can alter her diet and lifestyle to ensure that Pam receives the nutrients she needs for herself and for her baby.
The word family cannot be described or translated by one single universal definition. Different people have different views and meanings as to what a family means to them, but however different all families share similar characteristics. The Oxford Dictionary describes a family as a group consisting of parents and children living together in a household of common descent (2014). However, in today's society, families are evolving and changing in the way that is much different than the traditional nuclear family. As noted by NY Times, in today's society a family can be comprised of a single mother or father, gay/lesbian couple, couples that are unmarried and living together with their children, inter-racial marriages and couples, raising kids from behind bars (incarcerated) and even going from friends to caretakers (Angier, 2013). The term family in today's society is so dynamic, and it is the responsibility of all obstetric nurses to understand the changing family dynamic to be able to assess and determine if the proper care can be given to a newborn based on the education level, psychosocial status, welfare and support of the patient so that the newborn can grow up in an optimal environment with their new family.
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.
This gave rise to nonvascular plants like, mosses, liverworts, and hornworts. The second period of plant evolution began 425 million years ago was the diversification of plants with vascular tissue allowing plants to grow much taller and rise above the ground. The next period of plant evolution is the origin of seeds, about 360 million years ago. Seeds are embryos packed along with food in a protective covering. Last is flowering plants about 140 million years ago, which is seeds within protective chambers called ovaries. Animal evolution begins when an animals egg and sperm fuse, producing a zygote. The zygote splits by mitosis and forms an blastula, which usually is a hollow ball of cells. One side of the blastula folds in forming a gastrula, which develops into an embryo with a two-layered wall and an opening on one end. After the gastrula stage animals develop into
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.
From here, the reproductive system leads into the female, with the semen being inserted. It fertilizes the egg and then a baby is born.
The merger of two germinal cells, one being a sperm cell and the other being an egg cell, is complete within twelve hours, at which time the egg is fertilized and becomes a zygote containing forty six chromosomes required to create a new human life. It is during this remarkable process when conception occurs. Conception confirms life and makes that undeveloped human one of a kind (Rorvik & Shettles, 1983, p. 16). Many researchers, as well as scientists, identify the first moments of life as the instant when a sperm cell unites with an ovum, o...
The egg is covered with a hard protein shell that called a zona. No sperm is just strong enough to break this shell, so the sperm has to introduce itself properly first. Once the sperm goes through and completes all of the challenges. The egg and sperm take over and begin developing a baby. The development of a baby goes through three trimesters before the parents get to meet their “Life’s Greatest
Now I will start with the stages of meiosis. The first stage of meiosis is interphase. Just interphase alone is broken up into 3 different stages, G1 phase, S phase, and G2 phase. In G1 phase the cells grow to get ready for the cell division. In S phase the DNA gets synthesized which
Whether it is a mammal, sea creature, or even insects, they all start life as humans do. Directly following conception, there is an unreplaceable genetic code that is unique and made to thrive but is destroyed without ever getting the chance to reach its full potential. 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 Developmental Facts)....
The embryos are usually extras that have been created in IVF (in vitro fertilization) clinics where several eggs are fertilized in a test tube, but only one is implanted into a woman (Crosta, Paragraph 3). The blastocyst consists of an inner cell mass (embryoblast) and an outer cell mass (trophoblast). The outer cell mass becomes part of the placenta, and the inner cell mass is the group of cells that will differentiate to become all the structures of an adult organism(Crosta, Paragraph 4). In a healthy pregnancy, the blastocyst stage continues until implantation of the embryo in the uterus, at which point the embryo is referred to as a fetus. This usually occurs by the end of the 10th week of gestation after all the primary organs of the body have been created (Crosta, Paragraph 5). Human embryonic stem cells are the cells from which all 200+ kinds of tissue in the human body originate. When stem cells are obtained from living human embryos, the harvesting of such cells necessitates the destruction of the
Every choice made during the early development of a child has the potential of affecting the rest of their life. If every parent, educator, or caretaker raised a child with this statement in mind, children would be given the best chance at developing to their fullest potential. Early childhood development has many aspects to it, but the three main developmental areas are physical, cognitive, and socio-emotional. Each developmental stage is just as important as the next and becoming aware of how they work can help parents and caregivers better understand how to raise a child most effectively.
"Embryonic stem cells are derived from a four- or five-day-old human embryo that is in the blastocyst phase of development."(source). Before the embryonic stem is produced, the fertilized egg, a zygote, starts to multiply it's cells. Once the group of cells is set in the uterus, it becomes a blastocyst. The blastocyst consists of an inner and outer mass. The outer mass, the
Developmental Psychology is an area which studies how we as humans change over the period of our life span. The majority of the focus is broken into three categories: cognitive, physical and social change. The creation of who we are today comes down to the everlasting debate of nature versus nurture. This ongoing debate of what makes us who we are and which one is the driving force in development may be so simple that it’s complex. Rather than it being a conflict of nature “versus” nurture, it is very well possible both play an equal part in the development of us as humans. In the beginning, we start off as single cell in the form of a zygote. In that moment, where the DNA begin to form and the first seconds of life take place, the zygote is already experiencing interaction with the womb. In the process of determining why we are who are it is better to look more at the interactions of nature and nurture, analyzing how both have shaped us.
Child Birth can be a beautiful, yet unimaginable experience any mother and family member can encounter. It is a process of emotional and social involvements that make-up a natural human being. The familiarity of childbirth can play an important role in life for every individual, especially the mothers who are in labor or in delivery. Each moment during labor will become memories for the mothers to share with their grown up child in the future. Childbirth is a breath taking experience that can change someone’s life forever. The process of childbirth does not occur in a blink of an eye; in fact, it is more of a procedure that may take a few steps. Some mothers during labor, experience a severe amount of pain that medication can control and some
