What is a notochord
- Notochord is a mesodermally derived rod-like structure formed on the dorsal side during embryonic development in some animals. Animals with notochord are called chordates and those animals which do not form this structure are called non-chordates.
- Function: The main function of notochord is to support the body. As the embryo grows it becomes a part of the true backbone or vertebral column.
