Quizplus · Accepted Answer

The neural tube eventually thickens into three bulges that will form the three main regions of the brain: the hindbrain, the midbrain, and the forebrain. The ventricle is a fluid-filled cavity within the brain, the epigenetic structure refers to the way gene expression is influenced by external factors, and the amniotic sac is a membrane that surrounds and protects the developing fetus.
