Definition
| Dorsal axial mesoderm that differentiates as the notochord. |
|
|
Term
|
Definition
| Mesoderm derived from paraxial dorsal mesoderm that is organized into somites and will contribute to the axial skeleton, dorsal dermis, and skeletal muscles of the back and limbs. |
|

|
|
Term
|
Definition
| Mesoderm that lies lateral to the intermediate mesoderm that contributes to heart, blood vessels, blood cells, linings of the coelom, and mesodermal tissues of the limbs except muscles. |
|
|
Term
|
Definition
| Anterior loose mesoderm that contributes to the connective tissues and muscles of the face (along with neural crest cell derivatives). |
|
|
Term
|
Definition
| Thick bands of mesoderm that run longitudinally along each side of the notochord and neural tube and form the somites. |
