The notochord also plays a crucial role in the structure of a developing embryo. As it is the precursor to the spine, it can be thought of as a transient spine of the embryo, while the actual spinal cord develops from the neural tube [31]. WebAlso at that time the notochord develops cranially from the primitive node. By day 22 the primitive streak has regressed to between 10 and 20% of the embryo's length, and by day 26 has seemingly disappeared.
