The skull attachment suture model (with digital identification) is a biological teaching tool used to display the suture structure and name of adult skulls. This model simulates the shape of a real skull and clearly identifies the main skull sutures on the model, such as coronal sutures, sagittal sutures, and herringbone sutures. In biology teaching, this model can help students intuitively understand the connection methods between different parts of the skull, and learn the names and positions of different sutures. By observing the model, students can master the anatomical knowledge of the skull and understand the complexity and accuracy of the skull structure. The digital identification function enables students to more easily identify and remember various sutures, improving learning efficiency.
