дефекти на нервните патишта

Defective developments of the brain or spinal cord. By the mid embryonic stage (5 weeks in humans), a neural tube extends from the top of the head to the lower end of the spinal column. Later, this tube becomes the brain and spinal chord. Spina bifida and anencephaly are examples of neural tube defects.
