Your deep intrinsic muscles. One is located on the ventral side of your body at the top of your neck inferior to your occipital bone and it's one of three muscles. The other one is part of the first one, but attaches to the head. One One starts at your sacrum and ilium and goes up on your lumbar vertebrae attaching to spinous processes.
