Cooper Krone Exam 1 Practice

The key idea is how these intrinsic back muscles connect between adjacent vertebrae to control small movements and stabilize the spine. Rotatores are short (breves) or long (longi) muscles that span from the transverse process of one vertebra up to the spinous process of a higher vertebra. Specifically, Rotatores Breves attach from the transverse process of a vertebra to the base of the spinous process of the vertebra immediately above (one level up). Rotatores Longi go up two levels to the spinous process above. Interspinales, by contrast, run between adjacent spinous processes, and Intertransversarii run between adjacent transverse processes. So the described path—from a spinous process above to a transverse process below—doesn’t match those patterns, whereas Rotatores Breves represent the closest cross-level connection among the options. That’s why Rotatores Breves is the best choice here.
