Central Nervous System - Secondary Brain Vesicles

These 5 secondary vesicles developed from the initial 3 primary vesicles of the early neural tube, by division of the forebrain and hindbrain regions.

  1. Telencephalon
  2. Diencephalon
  3. Mesencephalon
  4. Metencephalon
  5. Myelencephalon

The more mature brain with five brain vesicles: the horizontal and lateral views correspond to GD 11.5 in rats and 33 ± 1 in humans.
