The spinal model is an important teaching tool used in biology education to showcase the structure of the human spine. This model is typically made of durable plastic or resin and displays in detail various parts of the spine, including the cervical, thoracic, lumbar, sacral, and caudal vertebrae. In biology teaching, spinal models can help students intuitively understand the anatomical structure of the spine, learn the characteristics of each part of the vertebrae, the connection methods between vertebrae, and the curvature of the spine. By observing and operating the model, students can master the structure and function of the spine, understand the role of the spine in supporting the body, protecting the spinal cord, and participating in movement.
