Answer 2

Vertebrae, along with intervertebral discs, compose the vertebral column, or spine. It extends from the skull to the coccyx and includes the cervical, thoracic, lumbar, and sacral regions. The spine has several major roles in the body that include the protection of the spinal cord and branching spinal nerves, support for thorax and abdomen, and enables flexibility and mobility of the body. The intervertebral discs are responsible for this mobility without sacrificing the supportive strength of the vertebral column. The lumbar region contains five vertebrae, denoted L1-L5. The intervertebral discs, along with the laminae, pedicles, and articular processes of adjacent vertebrae, create a space through which spinal nerves exit. The lumbar vertebrae, as a group, produce a lordotic curve

Lumbar vertebrae provide points of attachment for numerous muscles: erector spinae, interspinales, intertransversarii, latissimus dorsi, rotatores, and serratus posterior inferior.
