Ans;C. Paraxial mesoderm
The structure labelled as ‘G’ in the picture above represents Somites.
Somites develop from Paraxial mesoderm.
- Paraxial mesoderm form somitomeres which give rise to Somites (metamers or primitive segments).
- Intra-embryonic mesoderm is formed by proliferation of cells in primitive streak & it separates ectoderm & endoderm except in these region – Prochondral plate-Cloacal membrane
- Caudal to prochordal plate in midline as this place is occupied by notochord.
