Spina bifida (SB) is a neural tube defect (NTD) that has an increased risk of fatal and disabling effects if not repaired early, i.e. within the first 24 to 48 hours of life. (bvsalud.org)

The neural tube is a flat piece of tissue that grows into a tube shape. (clevelandclinic.org)
The brain development in the embryo (developing baby) begins with forming a neural plate (a layer of tissue with special cells) at around two weeks after conception. (momjunction.com)
