L5 is the fifth and lowest vertebra in the lumbar region of the spine, possessing specific structural features.
Understanding L5 Vertebra
The L5 vertebra is crucial for supporting the upper body and connecting the spine to the pelvis. It's designed to bear a significant amount of weight and facilitate movement.
According to the reference, L5 is comprised of two main parts:
- Vertebral Body: Located at the front, it's the main weight-bearing component.
- Vertebral Arch: Situated at the back, it features bony protrusions that serve as attachment points for ligaments. These protrusions include:
- Spinous Process: A single, prominent projection in the middle.
- Transverse Processes: Two projections on the sides.
These processes are essential for muscle and ligament attachments, providing stability and enabling spinal movement.
