Describe in detail the effects of a deficiency of folate/folic acid
(1/4)
Spina bifida - A neural tube defect which occurs when the base of the spinal fails to close
Causes paralysis of the lower limbs
Anencephaly - A neural tube defects which occurs when the top of the spine fails to close and the brain, skull and scalp do not develop
Baby rarely survives
