Examples of prenatal in the following topics:
-
- Prenatal diagnosis and prenatal screening are methods for testing for diseases or conditions in a fetus or embryo before it is born.
- There are three purposes of prenatal diagnosis:
- The primary method for sex determination is prenatal ultrasound.
- Diagnostic prenatal testing can be done by invasive or noninvasive methods.
- Infer the type of prenatal diagnostic test that should be used in a particular case
-
- 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.
- Exposure to teratogens during the prenatal stage can significantly raise the risk of birth defects.
- Other teratogens that affect prenatal development include radiation, pollution, and infectious disease.
- Discuss the impacts of teratogens and maternal stress on prenatal development
-
- 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).
-
- 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.
-
- 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.
- Analyze the differences between the various stages of human life - prenatal, toddler, early and late childhood, adolescence, early and middle adulthood and old age
-
- 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).
-
- The urinary system develops from the intermediate mesoderm during prenatal development.
-
- Down syndrome can be identified in a baby at birth or by prenatal screening.
- Many standard prenatal screens can discover Down syndrome.
- Genetic counseling along with genetic testing, such as amniocentesis, chorionic villus sampling (CVS), or percutaneous umbilical cord blood sampling can be offered to families who may have an increased chance of having a child with Down syndrome, or where normal prenatal exams indicate possible problems.
-
- 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.
