Question
Differentiate between notochord and nerve cord
Distinguish Between
Solution
| Notochord | Nerve cord |
| All vertebrate embryos have a flexible rod-shaped body called the notochord. | The dorsal nerve cord is a hollow cord that connects the notochord to the body. |
| It is made up of cells produced from the mesoderm and determines the embryo's primitive plane. | It is made up of a rolling section of the ectoderm that forms the hollow tube. |
| In higher vertebrates, the vertebral column is present in place of the notochord. | The central nervous system is developed from the nerve cord. |
