[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":
There are three stages of fetal development. The first stage is the germinal stage begins at conception and is the shortest stage. The second stage is the embryonic stage which begins around the third week of pregnancy and ends at the eighth week. The final stage is the fetal stage which begins at the ninth week of pregnancy and lasts until birth.
The fetal adrenal cortex can be identified within four weeks of pregnancy. [2] The adrenal cortex originates from the thickening of the intermediate mesoderm . [ 3 ] At five to six weeks of gestation, the mesonephros differentiates into a tissue known as the gonadal ridge.
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.
