What is the primary function of the Rotatores muscle?

• A. Flexion of the lumbar spine
• B. Extension of the cervical spine
• C. Rotation of the vertebral column
• D. Stabilization of the sacroiliac joint

Answer: (C)

The primary function of the Rotatores muscle is indeed the rotation of the vertebral column. The Rotatores are a group of small, deep muscles located between the vertebrae of the spine, primarily in the thoracic region. They attach from the transverse process of one vertebra to the spinous process of the vertebra above it. When these muscles contract, they facilitate rotation of the vertebrae toward the opposite side, thus allowing for complex movements and stabilization of the spine during activities that require trunk rotation. This action is crucial not only for movements such as twisting and turning but also for maintaining postural control and balance of the spine during various physical activities.
