Study Notes

Notochord Development

The initial location of the notochord in the developing embryo is between the ectoderm and the endoderm, in the dorsal region.

Notochord Function

The notochord provides a flexible, rod-like structure that gives support and shape to the embryo.
It also serves as an organizing center, inducing the formation of surrounding tissues.

Notochord Migration

After detachment from the underlying endoderm, the notochord comes to lie between the neural tube and the dorsal mesoderm.

Notochord Origin and Formation

The notochord originates from the dorsal, median region of the embryo.
The notochord is formed from the mesodermal germ layer, specifically from the chordamesoderm.
