Introduction :-
The notochord is a defining characteristic of the Chordate phylum and is present in various forms throughout the lifespan of chordates, including in their embryonic and larval stages. The notochord acts as a supportive structure, providing rigidity and stability to the developing body. It also acts as a signaling center, influencing the differentiation and development of surrounding tissues, such as the neural crest cells, which give rise to the nervous system
