What are the Teaching Applications of Anatomical Models of the Human Nervous System?

The anatomical model of the human nervous system is an anatomical tool used for teaching and training. By simulating the structure and distribution of the real human nervous system, it helps learners intuitively understand the composition and function of the nervous system. Its core value lies in transforming abstract physiological knowledge into observable and manipulable physical models. It is suitable for teaching scenarios in fields such as medicine, biology, and nursing, and is especially suitable for training, assessment, demonstrations, and explanations for students over 18 years of age and professionals.

The nervous system consists of the central nervous system (brain and spinal cord) and peripheral nerves (nerve trunks, ganglia, etc.). Its structure is intricate, especially in the intracranial, spinal canal, and facial regions, where nerves run through bony foramina, fascia, and blood vessels. Accurate spatial understanding is difficult to achieve using only two-dimensional atlases. The neural system model, through high-precision reconstruction of the trigeminal nerve branching pathways within the temporal bone, the entire course of the facial nerve from the brainstem to the facial muscles, and the distribution patterns of spinal nerves within the intervertebral foramina, allows students to "see and touch" key anatomical locations such as the "supraorbital foramen," "stylomastoid foramen," and "intervertebral foramen," thus transforming abstract terminology into three-dimensional coordinates for deeper memorization.

Modern nervous system anatomical models often integrate 3D courseware, virtual simulation, or augmented reality (AR) technology, supporting rotation, scaling, layered disassembly, and dynamic demonstrations. For example, students can simulate the anatomical process using the 3D model, observing how nerve impulses are transmitted along axons to synapses, and understanding the mechanisms of excitatory and inhibitory neurotransmitters. This interactive learning not only enhances interest but also deepens understanding of neural conduction pathways and functional integration through role-playing and group discussions.

Compared to cadaver specimens, nervous system anatomical models are free from ethical controversies, can be mass-produced, and are easy to preserve and maintain, effectively alleviating the shortage of teaching resources. Their structural consistency avoids cognitive biases caused by individual differences, ensuring that every student receives the same learning experience. At the same time, the model can be used with QR codes to link digital resources, enabling online and offline teaching to be integrated, thereby improving the flexibility and coverage of teaching.
