White supremacy or white supremacism is a racist ideology centered upon the belief, and promotion of the belief, that white people are superior in certain characteristics, traits, and attributes to people of other racial backgrounds and that therefore white people should politically, economically and socially rule non-white people.
Neural tube defects occur when the bones of the spine do not correctly form, leaving the spinal cord and its nerves and coverings to protrude out through the skin (or lie just beneath it). The use of folate vitamins during pregnancy has decreased the incidence of neural tube defects.
Neural tube defects (NTDs) are birth defects of the brain and spinal cord. They happen in about 3,000 pregnancies each year in the United States. A babyâs neural tube normally develops into the brain and spinal cord. It starts out as a tiny, flat ribbon that turns into a tube by the end of the first month of pregnancy. NTDs happen if the tube doesnât close completely. NTDs can cause serious problems for babies, including death.
