||The '''prosencephalon''' and '''rhombencephalon''' are primary brain vesicles. The others are distractors using your lack of understanding of what the terms mean.
||The '''oocyte''' is present before fertilization, the '''conceptus''' refers to all the products of fertilization and is not a developmental stage, '''polar bodies''' are small exclusion bodies enclosing the excess DNA from oocyte meiosis. I did not discuss in detail '''blastomeres'''  a term often used to describe the first cells formed from zygote mitosis.
