Examples of Prenatal development in the following topics:
-
- Prenatal development is highly influenced by the inheritance, expression, and regulation of genes.
- Prenatal development is the process that occurs during the 40 weeks prior to the birth of a child, and is heavily influenced by genetics.
- There are three stages of prenatal development—germinal, embryonic, and fetal.
- Prenatal development is also organized into trimesters: the first trimester ends with the end of the embryonic stage, the second trimester ends at week 20, and the third trimester ends at birth.
- For this reason, genetics play a particularly important role in prenatal development.
-
- Prenatal development is the process of rapid change and growth that occurs in the 40 weeks prior to the birth of a child.
- Prenatal development is the process that occurs during the 40 weeks prior to the birth of a child.
- There are three stages of prenatal development: germinal, embryonic, and fetal.
- Prenatal development is also organized into three equal trimesters, which do not correspond with the three stages.
- The remainder of prenatal development occurs during the fetal stage, which lasts from week 9 until birth (usually between 38 and 40 weeks).
-
- They are characterized by prenatal development, toddler, early childhood, late childhood, adolescence, early adulthood, middle adulthood, and old age.
- Prenatal development is the process during which a human embryo gestates during pregnancy, from fertilization until birth.
- The terms prenatal development, fetal development, and embryology are often used interchangeably.
- The development of this skill relies on the resolution of other stages.
- Analyze the differences between the various stages of human life - prenatal, toddler, early and late childhood, adolescence, early and middle adulthood and old age
-
- Prenatal development is the process that occurs during the 40 weeks prior to the birth of a child.
- During each prenatal stage, environmental factors affect the development of the fetus.
- Other teratogens that affect prenatal development include radiation, pollution, and infectious disease.
- Any form of prenatal stress felt by the mother can have negative effects on various aspects of fetal development, and can cause harm to both mother and child.
- Discuss the impacts of teratogens and maternal stress on prenatal development
-
- The urinary system develops from the intermediate mesoderm during prenatal development.
- Three sets of kidneys develop sequentially in the embryo: The pronephros is rudimentary and nonfunctional, and regresses completely.
- The kidneys develop in the pelvis and ascend during development to their adult anatomical location at T12-L3.
- The urinary bladder develops from the upper end of the urogenital sinus, which is continuous with the allantois.
- It develops into the part of the urogenital system (kidneys and gonads), as well as the reproductive system.
-
- Pregnancy is the state of fertilization and development of one or more offspring within a woman's uterus.
- The prenatal offspring or conceptus is referred to as an embryo or fetus.
- In many societies' medical or legal definitions, human pregnancy is somewhat arbitrarily divided into three trimester periods as a means to simplify reference to the different stages of prenatal development.
- During the second trimester, the development of the fetus can be more easily monitored.
- This system bases stages on the development of structures
instead of days of development or size of the conceptus.
-
- But today, the concept of nurture has expanded to refer to any environmental factor - which may arise from prenatal, parental, extended family, or peer experiences, or even from media, marketing, and socioeconomic status.
- Environmental factors could begin to influence development even before it begins: a substantial amount of individual variation might be traced back to environmental influences that affect prenatal development.
-
- In post-traumatic stress disorder there appears to be lower-than-normal cortisol release, and it is thought that a blunted hormonal response to stress may predispose a person to develop PTSD.
- There is growing evidence that prenatal stress can affect HPA regulation in humans.
- Children who were stressed prenatally may show altered cortisol rhythms.
- Prenatal stress has also been implicated in a tendency toward depression and short attention span in childhood.
- However, there is no clear indication that HPA disregulation caused by prenatal stress can alter adult behavior.
-
- Behavior can have an impact on genetic makeup, even as early as the prenatal period.
- Prenatal exposure to certain substances, particularly drugs and alcohol, has detrimental effects on a growing fetus.
- The most serious consequences of prenatal drug or alcohol exposure involve newborn addiction and fetal alcohol syndrome (FAS).
- Fetal alcohol syndrome affects both physical and mental development, damaging neurons within the brain and often leading to cognitive impairment and below-average weight.
-
- Prenatal diagnosis is a way to screen a fetus for diseases and/or conditions that may increase morbidity and/or mortality.
- Prenatal diagnosis and prenatal screening are methods for testing for diseases or conditions in a fetus or embryo before it is born.
- The primary method for sex determination is prenatal ultrasound.
- Diagnostic prenatal testing can be by invasive or noninvasive methods.
- Infer the type of prenatal diagnostic test that should be used in a particular case
