The term SPINE PART can be solved by two crossword solutions: DISC and DISK. The spine is an important part of the human body, as it is the central structure that supports the body and allows for movement. The spine is made up of vertebrae, which are separated by discs or disks. The discs are made up of a tough outer layer and a soft inner layer, and they act as shock absorbers for the spine. The disks are similar to discs, but they are more flexible and provide more cushioning for the spine. Both discs and disks are important components of the spine, and they help to keep the spine healthy and functioning properly.
