Detailed explanation-1: -Cervical Spine-7 vertebrae. Thoracic Spine-12 vertebrae. Lumbar Spine-5 vertebrae. Sacral Spine-5 fused vertebrae.

Detailed explanation-2: -Your lumbar spine consists of the five bones (vertebra) in your lower back. Your lumbar vertebrae, known as L1 to L5, are the largest of your entire spine. Your lumbar spine is located below your 12 chest (thoracic) vertebra and above the five fused bones that make up your triangular-shaped sacrum bone.

Detailed explanation-3: -The lumbar spine contains 5 vertebrae, labeled L1 to L5, which progressively increase in size going down the lower back. The vertebrae are connected with joints at the back to enable bending and twisting movements of the spine.

Detailed explanation-4: -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-5: -The C5-C6 spinal motion segment includes the following structures: C5 and C6 vertebrae. These vertebrae are each composed of a vertebral body, a vertebral arch, and 2 transverse processes. Together they form paired, synovial facet joints with gliding movements.
