'''Chordamesoderm''', also known as '''axial mesoderm''', is a type of [[mesoderm]] that lies along the central axis, under the [[neural tube]].
* will give rise to notochord
* starts as the notochordal process, whose formation finishes at day 20.
* important not only in forming the notochord itself but also in inducing development of the overlying ectoderm into the neural tube
* will eventually induce the formation of vertebral bodies.
* ventral floor of the notochordal process fuses with endoderm.
* The notochord will form the [[nucleus pulposus]] of interverterbral discs. There is some discussion as to whether these cells contributed from the notochord are replaced by others from the adjacent mesoderm.
It gives rise to the [[notochordal process]] which later becomes the [[notochord]]
