NEET PG DENTAL EXAM

Detailed explanation-1: -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-2: -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-3: -Most people have 5 lumbar levels (L1-L5), although it is not unusual to have 6. Each lumbar spinal level is numbered from top to bottom-L1 through L5, or L6. The low back vertebral bodies are larger, thicker block-like structures of dense bone. From the front (or anterior), the vertebral body appears rounded.

Detailed explanation-4: -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.
