Anencephaly occurs when the head end of the neural tube fails to close, resulting in the absence of major parts of the brain, skull, and scalp. Megalencephaly is an enlargement of the brain, Rachischisis is an incomplete closure of the spinal cord, and Spina bifida is a neural tube defect where the spinal cord, vertebral column, and surrounding structures do not form properly.
