Maternal physiological changes in pregnancy are the adaptations that take place during pregnancy that enable the accommodation of the developing embryo and fetus. These are normal physiological adaptations that cause changes in behavior , the functioning of the heart , blood vessels , and blood , metabolism including increases in blood sugar ...
The fetal endocrine system is one of the first systems to develop during prenatal development of a human individual. The endocrine system arises from all three embryonic germ layers. The endocrine glands that produce the steroid hormones, such as the gonads and adrenal cortex, arise from the mesoderm.
Childhood is the age span ranging from birth to adolescence. [7] In developmental psychology, childhood is divided up into the developmental stages of toddlerhood (learning to walk), early childhood (play age), middle childhood (school age), and adolescence (puberty through post-puberty). Various childhood factors could affect a person's ...
The fetal origins hypothesis (differentiated from the Developmental Origins of Health and Disease hypothesis, which emphasizes environmental conditions both before and immediately after birth) proposes that the period of gestation has significant impacts on the developmental health and wellbeing outcomes for an individual ranging from infancy to adulthood.
With the brain, this process happens early in development, again during puberty, and pregnancy probably reflects another wave of cortical refinement.” Increase in brain white matter during pregnancy
The process known as decidualization occurs when the endometrium changes both physiologically and morphologically in order to support and maintain an early pregnancy. [21] The final effect of endometrial cell differentiation and lymphoid cell influx is the formation of a tissue that is functionally distinct.
Prenatal and/or early postnatal exposure to alcohol (ethanol) has been found to have a negative effect on child's neuroendocrine and behavioral factors. [20] Alcohol passes through the placenta on being ingested by the mother during her pregnancy, and makes its way to the baby in utero . [ 20 ]
Prenatal development (from Latin natalis 'relating to birth') involves the development of the embryo and of the fetus during a viviparous animal's gestation.Prenatal development starts with fertilization, in the germinal stage of embryonic development, and continues in fetal development until birth.
