Antenatal instruction of Foundation

The nutrition of pregnant women: study of modern neuroanatomy and neurophysiology, fertilized eggs give birth to a neural tube in the 4th week, to respond to a stimulus; 8th week of the cerebral cortex has a rough Division, parent information more sensitive; 23rd week, structure formation in the cerebral cortex of the fetus; to prenatal brain development is basic training. Therefore, adequate nutrients in the blood of pregnant women, can improve brain development, intelligent. From the nutritional point of view, the brain is a finicky optional drinks \"gourmets\", a distinct likes and dislikes about the uptake of nutrition. To produce a good mind, must be in the brain \"architecture\" during the most vigorous, continuous replenishment \"construction materials\". This is the material basis of fetal receive antenatal instruction. In the nutrition of pregnant women should be aware of the following two points: one is comprehensive and reasonable to uptake nutrients to support development of fetal head; the second is to avoid external physical and chemical nature of hazardous materials such as damage to the fetal brain, because the brain to harmful substances during the development process more sensitive than other organs.

Pregnant women\'s emotions: medical study found that because of fetal life in the matrix, in this ever-changing specific environment, the behaviour of pregnant women, especially the emotional changes, through the chemical composition of maternal blood and hormone secretion changes affect fetal development. For example, when pregnant women fear, nervous, vascular contraction of in vivo, on the amount of fetal blood supply are reduced, if this situation persists, can cause effects on fetal brain development: pregnant woman too nervous, secreted by the adrenal gland is excessive will also impede the development of the fetus; excessive fluctuation of mood in pregnant women, may lead to abortion.

From this, provide nutrition for fetal brain development, avoid the effects of various harmful substances while pregnant women ease, emotional stability, rule of life, which is the basis for antenatal instruction.
