The rotatores are small muscles located in the back, specifically in the spinal column. They are part of the deep layer of the erector spinae muscle group and are situated between the vertebrae. Their primary function is to assist in the rotation and stabilization of the spine, allowing for controlled movement and posture. These muscles are found in the thoracic region of the spine and connect the transverse processes of one vertebra to the spinous process of the vertebra above it. The rotatores play a crucial role in maintaining spinal alignment and facilitating movements such as twisting and bending.
