The significance of the normal lumbar spine combination model

The significance of the normal lumbar spine combination model lies in helping learners systematically understand the normal anatomical structure and physiological functions of the lumbar spine. It is an important auxiliary tool for medical teaching, rehabilitation training and research on spinal diseases. This model is made in accordance with the real scale of the human lumbar vertebrae, fully presenting key structures such as the vertebral body, intervertebral discs, foramina, transverse processes, spinous processes and articular processes. Some parts are also equipped with spinal cord, nerve roots and intervertebral disc tissues, visually presenting the mechanical relationships and neural pathways of the lumbar vertebrae. Through observation and operation, learners can clearly understand the structural characteristics, movement patterns of the lumbar vertebrae and their role in supporting and protecting the spinal cord.

In addition, this model can be used to teach and demonstrate the principles of flexion, extension, rotation and other movements of the lumbar vertebrae, helping students understand the stability and force changes of the spine. In the clinical and rehabilitation fields, it can also be used to explain the occurrence mechanisms of common diseases such as lumbar spine disorders and intervertebral disc protrusion. The model structure is intuitive and detachable, which is convenient for teaching demonstration and practical training. Overall, the normal lumbar spine combination model has significant educational and practical value in promoting anatomical teaching, guiding clinical diagnosis and treatment, and enhancing learning outcomes.
