Central Nervous System - Primary Vesicles
These 3 primary brain vesicles develop initially due to the neural plate being broader at the cranial (brain) end that the narrower caudal (spinal cord) end. When the plate fuses to form a tube, these 3 initial expansions (vesicles) result.
- forebrain (prosencephalon)
- midbrain (mesencephalon)
- hindbrain (rhombencephalon)
- Development of the three primary brain vesicles on GD 10.5 in rats and 26 ± 1 in humans.
- Corresponding shading between panels illustrates the earlier origins of different regions from the three original brain vesicles with a horizontal and lateral view, respectively.
- Later they will develop into the 5 secondary vesicles (telencephalon - diencephalon - mesencephalon - metencephalon - myelencephalon)
| Neural Tube | Primary Vesicles | Secondary Vesicles | Adult Structures |
