Detailed explanation-1: -Cervical Spine-7 vertebrae. Thoracic Spine-12 vertebrae. Lumbar Spine-5 vertebrae. Sacral Spine-5 fused vertebrae.
Detailed explanation-2: -Vertebrae. As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx.
Detailed explanation-3: -Five (or in some cases, six) vertebrae make up the lumbar spine, which provides support for much of the upper body and is rather flexible. Lumbar vertebrae are larger than the thoracic or cervical vertebrae, as they have to bear the weight of the spine and the head.
Detailed explanation-4: -The L4 and L5 are the two lowest vertebrae of the lumbar spine. Together with the intervertebral disc, joints, nerves, and soft tissues, the L4-L5 spinal motion segment provides a variety of functions, including supporting the upper body and allowing trunk motion in multiple directions.
