In some chordates, the notochord acts as the primary axial support of the body throughout the animal’s lifetime. WebThe notochord will begin the shape changes in MHP cells. These cells will decrease in height and become wedge-shaped. Another type of hinge point occurs dorsal-laterally, referred to as dorsal-lateral hinge point (DLHP). These regions furrow and change shape in the same way as MHP cells do before connecting together to form the neural tube. raw spinefin halibut recipe
