What is the function of the nucleus pulposus in adult? Not Embryo
Answer 1:

The function of the nucleus pulposus (the remnant of the notochord from the embryo) is to distribute hydraulic pressure within each spinal disc under compression - that might sound confusing but really what it means is that the nucleus pulposus helps provide cushioning and lubrication between the bones in the spine. Think about every time you jump off of something on to the ground. That creates a lot of compression on your spinal column and the nucleus pulposus help to redistribute this pressure throughout the disc to prevent breaks.
