Answer
The primary vesicle of the brain are the forebrain or prosebcephalon, the midbrain or mesencephalon, and the hind brain or rhombencephalon. During the 5th week of development the prosencephalon differentiates into telencephalon and diencephalon. The rhombencephalon also forms secondary vesicles, the metencephalon and the myelencephalon.
Work Step by Step
The folllowing are the parts of the brain that develop from these embryonic vesicles:
From Prosencephalon:
telencephalon.> cerebral hemispheres
diencephalon>> thalamus, epithalamus and
hypothalamus
From Mesencephalon midbrain and cerebral aqueduct
From Rombencephaalon
metencephalon>>pons, cerebellum and part of 4th
ventricle
myelencephalon>>medulla oblongata and part of 4th
ventricle
