Interspinous ligaments serve to limit which motion during spinal movements?

Interspinous ligaments play a crucial role in stabilizing the spine during various movements. Their primary function is to limit excessive flexion and rotational movements between adjacent vertebrae. These ligaments are located between the spinous processes of the vertebrae, providing support and preventing excessive separation of these processes during flexion of the spine.

When the spine flexes, the interspinous ligaments become taut, which helps to restrict further flexion and provide a stabilizing effect. Additionally, they also contribute to limiting some degree of rotation, as too much rotation can lead to instability and potential injury to the spine.

The choice indicating both flexion and rotation as the movements limited by the interspinous ligaments encompasses the primary functions of these ligaments effectively, making it the most accurate answer.
