Fetal programming, also known as prenatal programming, is the theory that environmental cues experienced during fetal development play a seminal role in determining health trajectories across the lifespan. Three main forms of programming that occur due to changes in the maternal environment are:
The thrifty phenotype hypothesis is the idea that if an organism suffers from inadequate nutrition in fetal development it will subsequently be predisposed to certain genetic outcomes as an adult. A study done examining glucose tolerance of individuals born during a famine in the Netherlands in 1944-1945 favors the “thrifty phenotype ...
The Gregorc Style Delineator is a self-scoring written instrument that elicits responses to a set of 40 specific words. [3] Scoring the responses will give values for a model with two axes: a "perceptual space duality," concrete vs. abstract, and an "ordering duality," sequential vs. random [4] The resulting quadrants are the "styles":
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.
Learning styles refer to a range of theories that aim to account for differences in individuals' learning. [1] Although there is ample evidence that individuals express personal preferences on how they prefer to receive information, [2]: 108 few studies have found validity in using learning styles in education.
Maternal fetal stress transfer is a physiological phenomenon in which psychosocial stress experienced by a mother during her pregnancy can be transferred to the fetus. Psychosocial stress describes the brain's physiological response to perceived social threat. Because of a link in blood supply between a mother and fetus, it has been found that ...
The Synactive Theory of Newborn Behavioral Organization and Development [1] [2] (Synaction n., or Synactive adj. [from the Greek syn “together” and the Latin actio “action,” resulting in: “together in action”]) suggests that development of the human fetus, and later newborn, proceeds through the constant balancing of approach and avoidance behaviors, leading to: (1) a continuous ...
Levels rise towards the end of pregnancy just before birth and current theory suggests three roles of CRH in parturition: [27] Increases levels of dehydroepiandrosterone (DHEA) directly by action on the fetal adrenal gland, and indirectly via the mother's pituitary gland. DHEA has a role in preparing for and stimulating cervical contractions.
