Question

multiple cholce question
failure of the inferior neural tube to close completely will result in:
spina bifida
hydrocephalus
anencephaly

Explanation:

Neural tube defects occur when the neural tube fails to close properly during embryonic development. The inferior (lower) part of the neural tube is related to spinal cord development. Spina bifida is a neural tube defect where the spinal cord and/or its protective covering (meninges) protrude through an opening in the spine (vertebral bones) due to incomplete closure of the lower neural tube. Hydrocephalus is an accumulation of cerebro - spinal fluid in the brain ventricles (not directly due to inferior neural tube closure failure). Anencephaly is a severe defect where large parts of the brain and skull are missing, which is due to failure of the superior (upper) neural tube to close.

Answer:

spina bifida
