The small lumbar vertebrae and coccygeal bone model is a teaching and display tool specifically designed for the anatomy of the lower lumbar region. It has distinct advantages such as clear structure, portability, and strong targeting. Firstly, this model accurately reproduces the morphological features of the human lumbar vertebrae and coccyx, including the vertebrae, intervertebral spaces, and the connection between the sacrum and coccyx, enabling learners to intuitively understand the structural composition and physiological curvature characteristics of the lower part of the spine.

Secondly, the model is small in size and light in weight, making it easy to carry and operate. It is suitable for classroom demonstrations, clinical explanations, and individual learning. Compared to the complete spinal model, it focuses more on key areas, which is helpful for concentrating on explaining common problems of the lumbar spine, such as lumbar disc herniation, lumbar muscle strain, and coccyx injury, thereby improving teaching efficiency.

In addition, most of the models are made of high-quality materials, which are sturdy and durable. Some of the products even come with elastic intervertebral discs or movable structures, enabling them to simulate basic bending and stress conditions, thereby enhancing the intuitiveness and interactivity of the teaching process.
