- Mesodermal and Endodermal
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
During gastrulation, the three primary germ layers form, each giving rise to specific tissues.
Step 2: Meaning
The notochord is a flexible rod-like structure forming the primary axial support in all chordate embryos.
Step 3: Analysis
The notochord develops from the chordamesoderm, a specialized region of the mesoderm along the embryo's midline. Its cellular origin is strictly mesodermal.
Step 4: Conclusion
The origin of the notochord is mesodermal.
Final Answer: (B)
