Lumbar Vertebra Sacrum Bone with Spinal Nerves is a detailed anatomical model designed to demonstrate the structure of the lower part of the human spine. The model clearly shows the lumbar vertebrae, sacrum and the spinal nerves emerging from the spinal column. It helps students understand the arrangement of the lower spinal bones and the pathway of spinal nerves that connect the spinal cord to different parts of the body. The model provides a clear visual reference for studying the anatomy of the lumbar region and the relationship between vertebrae and spinal nerves. This anatomical model is widely used in medical colleges, nursing institutes, physiotherapy training centers and biology laboratories for teaching spinal anatomy. The detailed structure and durable construction make it suitable for classroom demonstrations and practical learning.
