During embryonic development, the chordamesoderm gives rise to the notochord in vertebrates.

Examples

Researchers studied how the chordamesoderm signals to other tissues during early formation.
The chordamesoderm is crucial for the development of the notochord.
In vertebrate embryos, the chordamesoderm forms early in development.

Morphology

chordamesoderm = chorda + mesoderm (semi-transparent) = chorda + mesoderm

The term is a straightforward compound of 'chorda' + 'mesoderm', but both are technical combining forms so the composition is clear in biology but not to general learners.

Etymology

Chordamesoderm comes from parts that tell its job: chorda means 'cord' (like the English word 'cord') and meso- + -derm mean 'middle' and 'skin' or 'layer'. So chordamesoderm is the middle layer in an embryo that becomes the notochord, the early 'back cord' that helps form the spine.
