Where does the Multifidus muscle insert?

The Multifidus muscle is a deep spinal muscle that plays a crucial role in stabilizing the vertebral column during movement. Its insertion is specifically into the spinous processes of vertebrae above the level of its origin. This configuration allows the Multifidus to effectively pull the spinous processes together, contributing to spinal extension and rotational stability of the spine.

The muscle originates from several areas, including the sacrum and the transverse processes of the lumbar vertebrae, but it distinctly inserts into the spinous processes of the vertebrae that are situated above its origin. This anatomical positioning is essential for the muscle's function and highlights its importance in maintaining spinal stability and posture.
