The third and fourth cranial nerves originate from the midbrain: 1  oculomotor nerve (CN III) 2  trochlear nerve (CN IV)
During embryonic development, the midbrain arises from the second vesicle, also known as the mesencephalon, of the neural tube. Unlike the other two vesicles, the forebrain and hindbrain, the midbrain remains undivided for the remainder of neural development. It does not split into other brain areas. while the forebrain, for example, divides into the telencephalon and the diencephalon.
