The Cranial model is an important teaching tool used in biology education to showcase and learn the structure of human skulls. This model simulates various parts of the real skull, including the frontal bone, parietal bone, temporal bone, occipital bone, ethmoid bone, plow bone, and mandible. In biology teaching, skull models can help students intuitively understand the anatomical structure and function of the skull, learn the names, positions, and connections between different parts of the skull. By observing and operating the model, students can master the protective function of the skull, understand the relationship between the brain, sensory organs, and the skull, as well as the importance of the skull in facial morphology and function.
