👉 Spinalis is a muscle group that runs from the head of the spine to the lower back. It consists of three main groups, or segments, of muscles: the anterior, middle and posterior lumbar muscles. These muscles are responsible for supporting the vertebrae (bones) in the spine and moving them up and down within the body's spinal column. The term "spinalis" is derived from Latin and refers to a group of muscles that work together to support the back and neck
