According to spinal anatomy, how many bones are found in the lumbar region?

The lumbar region of the spine consists of five vertebrae, which are labeled L1 through L5. This section is located between the thoracic vertebrae above it and the sacral vertebrae below it. The lumbar vertebrae are larger and stronger than the thoracic vertebrae due to their role in bearing weight and providing support for the upper body, as well as allowing for flexibility and movement in the lower back. Understanding the structure of the lumbar region is crucial for comprehending various conditions related to the spine, such as herniated discs and lower back pain, as well as for professions that involve physical activity or spinal health management.
