[0002] The neural conduction pathway is the pathway that conducts a certain information in the nervous system. This series of knowledge is not only the focus of teaching, but also can be considered a difficult point. Because this part of the knowledge is too abstract, it is often difficult for students to accurately understand and grasp the key points when the teacher explains it, so teachers generally use models to assist in teaching. However, the existing models cannot intuitively display the overall picture of the corticospinal tract, spinothalamic tract, thin fasciculus and cuneate fasciculus and lateral lemniscus conduction pathway, and cannot clearly show the relative positions of the cranial nerve nuclei and non-cranial nerve nuclei in different sections of the spinal cord, medulla oblongata, pons, and midbrain, as well as the arrangement and order of the ascending and descending fiber bundles.
