Question

Differentiate between notochord and nerve cord

Answer 1

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.
