fetal development case study

Fetal Stage of Development. The fetal stage of development begins at 9 weeks of gestation and ends with birth (Figure 10.16). Organs, tissues, and structures of the fetus continue to develop and begin to function. The fetus has its own circulation, and the umbilical cord connects the fetus to the placenta. The skin on the fetal abdomen closes ...

1. Nutrition. Both maternal under- and overnutrition may have consequences for fetal neurodevelopment. The detrimental effects of maternal undernutrition have been characterised in studies of individuals who were exposed to severe undernutrition in utero during the Dutch Hunger Winter. In early 1944, the western part of The Netherlands was under German occupation and endured severe food shortages.

Recent studies have shown that music can help pregnant women to relax. 96-99 Listening to music can also lead to fetal effects such as an increase in fetal movements and a decrease in uterine contractions. 100 101 An increase in fetal movement may be associated with fetal well-being. 41 In sum, music can be highly recommended for prenatal ...

The volume, titled "Studies in Fetal Behavior", reported results of a systematic study of fetal development by investigators of the Fels Institute of Yellow Springs, Ohio. The Monograph, focused exclusively on fetal heart rate as an indicator of behavior, was the first of a series of three reports by the group that year; the latter two were ...

The impact of stress on brain health begins in the womb. Both animal and human studies have found that prenatal maternal stress affects the brain and behavior of the offspring. Stressful life events, exposure to a natural disaster, and symptoms of maternal anxiety and depression increase the risk for the child having a range of emotional ...

Abstract. Background: Stillbirth is strongly related to impaired fetal growth. However, the relationship between fetal growth and stillbirth is difficult to determine because of uncertainty in the timing of death and confounding characteristics affecting normal fetal growth. Methods and findings: We conducted a population-based case-control ...

Normal fetal growth is a critical component for a healthy pregnancy and for ensuring the health and well-being of infants throughout childhood and adolescence. Pivotal to understanding the dynamics of human fetal growth and to defining normal and abnormal fetal growth is the development of standards for fetal anthropometric parameters, measured longitudinally throughout gestation.

Objectives: To assess cerebral growth and the development of fetal cortex using neurosonography in fetuses from pregnancies experiencing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) according to infection timing. Methods: Pregnancies with by SARS-CoV-2 during first and second trimesters were prospectively studied and matched with unaffected controls.

copy of " Case Studies" student handout ... As an extension, have students explore the effects of prenatal maternal smoking or drug use on embryonic and fetal development and growth.

Most drugs of abuse easily cross the placenta and can affect fetal brain development. In utero exposures to drugs thus can have long-lasting implications for brain structure and function. These effects on the developing nervous system, before homeostatic regulatory mechanisms are properly calibrated, often differ from their effects on mature systems.

Case Study | January 01 2001. Case Study: A 36-Year-Old Woman With Type 2 Diabetes and Pregnancy Diane M. Karl, MD. ... Commonly, however, women do not seek medical attention until after this period of early fetal development. Many women do not yet realize they are pregnant during this important period, especially if the pregnancy is not ...

Maternal nutrition plays a critical role in fetal growth and development. Although considerable effort has been directed towards defining nutrient requirements of animals over the past 30 y, suboptimal nutrition during gestation remains a significant problem for many animal species (e.g., cattle, pigs, and sheep) worldwide ().Despite advanced prenatal care for mothers and fetuses, ∼5% of ...

Case Study Dexter and Samantha are the parents of four healthy girls. During all four pregnancies, they had ultrasounds performed during the 20th week of pregnancy to determine the gender of the baby.

Introduction. Research in the Developmental Origins of Health and Disease has highlighted effects of maternal stress during pregnancy on long-term health outcomes among offspring [1-6].This reflects in part the effects of maternal stress hormones such as cortisol, which is important in promoting fetal neurodevelopment but which, at high levels, might have adverse effects that vary by infant ...

The fetal head is still large as the body straightens out. The arms and legs are formed, and can move and bend. • Sex organs are almost fully formed. • Toenail and fingernail growth begins. • The eyes move forward. The ears reach normal position. Now the face is well formed. Embryonic Fetal Development

Case Study. Chapter 10, Fetal Development and Genetics. Lauren has been a pediatric nurse at a children's hospital for the past 7 years. Recently she began a new job as a nurse in a genetics office. One of today's cases involves Emily and Brad Davis. Emily is a young white female who looks to be in her mid-twenties.

Abstract. Objective: To investigate whether maternal obstructive sleep apnea (OSA) is associated with changes in fetal growth trajectory. Study design: Retrospective review of pregnant women who underwent overnight polysomnography. Fetal growth was estimated using sonographic biometric measurements obtained during routine prenatal care.

This case study provides an introduction to fetal alcohol spectrum disorders, diagnostic issues, a detailed description of the individual's history, presenting symptoms, neuropsychological test results, and an integrated summary. We describe a 9-year old girl diagnosed with a fetal alcohol spectrum disorder (FASD): Neurobehavioral Disorder ...

Study with Quizlet and memorize flashcards containing terms like 9. A patient asks the nurse when her infants heart will begin to pump blood. What will the nurse reply? a. By the end of week 3 b. Beginning in week 8 c. At the end of week 16 d. Beginning in week 24 ., 1. What is the total number of chromosomes contained in a mature sperm or ovum? a. 22 b. 23 c. 44 d. 46, 5. The nurse is ...

This study aimed to investigate whether fetal growth trajectories (FGTs) could predict early childhood development, indicate intrauterine metabolic changes, and explore potential optimal and suboptimal FGTs. FGTs were developed by using an unsupervised machine-learning approach. Children's neurodeve …
