In the first month of pregnancy head and trunk appear and tiny arm buds begin to form, followed by leg buds. The early embryo seems to have a "tail", but this is really a protective covering for the spinal cord because the central nervous system (brain, spine and spinal cord) is so important. At this point of development the structures that eventually form the face and neck are becoming
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
To commence with, during development a human being grows at an astonishingly rapid pace. According to Guttmacher Institute, “89% of all abortions in the United States are performed in the first trimester of pregnancy.” (2005). In the first trimester (16 weeks), the baby’s eyes and eyelids, nose, mouth, and tongue have formed, and the baby's reproductive organs also develop. The cardiovascular system is the first system that begins to function. The baby’s heart begins to circulate their own blood, similar to his mother’s heart, twenty-two days after conception. Electrical brain activity can be detected at six or seven
Biological development of a fetus is vary rapid and complex over the nine-month period in the womb. When both the male spermatozoon and the female ovum combine it forms what is called a zygote which holds the twenty-three pairs of chromosomes. The zygote or the embryo undergoes cell division and makes its way to the uterine wall to implant itself, this process is completed about ten days after conception. By the end of the eighth week the organ systems have formed and human characteristics can start to be noticed. From the eighth week until birth the embryo is now labeled a fetus. Quickening can occur from the sixteenth week until birth, this is where the mother can feel the fetus moving. Around the twenty-second week viability can take place, this is where the fetus can survive outside the womb. The nine-month period of being pregnant is split into different trimesters. With the different trimesters there are different abortion procedures can be used to remove the fetus.
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.
Ultrasounds should be performed on expecting mothers to ensure the health of the fetus during the pregnancy. The ultrasounds can be used to make sure that the fetus is meeting the expected growth requirements per trimester. There are 3 trimesters during a normal pregnancy and each trimester has its own growth requirements to ensure that by the time the pregnancy is expected to be over the fetus should be fully developed. The First Trimester is weeks 1-12 of the pregnancy.(10-1) At the end of the first month, the embryo has a heartbeat, a two-lobed brain, and a spinal cord. By the end of the second month, the embryo is recognizable as a human and is called a fetus. After two months, the embryo has started to from arm and legs as well as fingers, ears, and toes. The fetus can be visibly identified as a male or female. By the end of the first trimester, the heart has 4 chambers (1-8). The Second Trimester is weeks 13-28 of your pregnancy.(10-2) By the
The brain continues to grow and rapidly develops in three stages known as Neurogenesis, Synaptogensis, and synaptic pruning. Neurogenesis describes the process of rapid division within the nervous system to create functional regions of the brain where most of the process is complete before birth while some regions continue to form after birth such as hippocampal cells. Synaptogensis forms new connections between neurons as over time connections increase in density where some only form one synapse and others form hundreds of thousands. Synaptic pruning removes synapses due to the fact some are only needed temporarily, some are damaged or become dysfunctional, or that some are not used often enough so they are removed for specialization. The newly formed fetus from weeks 9 to 12 shows signs of simple movement with reflexes in arms and legs while sex organs begin to differentiate. Fingers, fingerprints, and toes are fully formed around week 16 and around week 24 the fetus develops response to sound. More remarkably the brain doubles in size between week 16 and 28, while developing basic behavior. The fetus gains greater coordination skills as the cerebral cortex grows larger and personality also develops. Around the 28th week the fetus can mediate sensory input as thalamic brain connections form, such as responding to bright light from within the dark womb. Growth slows down around the 30th or 32nd week but the fetus continues to gain weight and by week 37 has developed all organ systems necessary to survive outside the uterus. Prenatal development ends with the birth of the fetus around 38 to 40 weeks
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.
Page 1 Child Growth and Development: "Life's Greatest Miracle" Paragraph In the video Life's Greatest Miracle, I was informed about how children are conceived, how they develop in the mothers body, and how amazing child birth can be. In the beginning it takes you through the steps of how sperm travels as for looking for an egg to fertilize. Although, in just one teaspoon of sperm there can be over 300 million sperm cells, only around 40% of them are usable. The other 60% can be deformed such as having two tales. The sperm can reach the Fallopian tube within 30 minutes, but it can be a 2 day swim just for sperm to reach an accepting egg. After the sperm that was strong enough to make it through the rough travel have met up with an egg, they
The concept fetus is used to denote the unborn human from the end of the eighth week after conception to the moment of birth, as distinguished from the earlier embryo (the product of conception from implantation in the uterus through the eighth week of development). A fetus contains all the organs and has the basic human form. (Rand)
First trimester: By 12 weeks of pregnancy the foetus will be fully formed. The ovum grows and develops certain important parts of the baby’s body such as spinal cord, nervous system, gastrointestinal system, heart and lungs in the first four weeks from conception. The heart starts beating and brain and other organs forms by eight weeks. At this stage, the face is formed and arms and legs start to move. The baby grows to 3 inches long and
Alexandra Tsiaras came up with a phenomenal way of describing conception to birth in his interview he did for Ted Talk. There were several things and little details that I truthfully did not know happened so fast during a woman’s pregnancy. It amazes me how people can go through with abortion after watching a video like Conception to Birth. Alexandra Tsiara’s visuals on conception to birth show a whole new outline of how fast a baby becomes a human, and that makes it that much more precious.
