Anatomical model of the human nasal cavity, oral cavity and throat Visual teaching aid: This model is designed as a clear visual teaching tool for the anatomy of the nasal cavity, oral cavity, and throat. Detailed internal anatomy: It shows the internal structure of the oral cavity under the trigeminal nerve network, displaying the mouth, nose, pharynx, and larynx inside the head, along with the structures of cerebral blood vessels and cranial nerves. Easy to understand: The model provides a detailed display of lesions in various parts of the nasal cavity, oral cavity, pharynx, and larynx, including rhinitis, polyps, and tonsillitis, so students and doctors can intuitively understand the structure and function of these regions. authenticity: Made according to real human body structure with a degree of simulation and realistic details; users can understand the complex anatomical relationships among the nasal cavity, oral cavity, pharynx and larynx and how these parts relate to one another. Wide range of uses: An anatomical model suitable for teaching and scientific research. It is appropriate for medical schools, laboratories, education and training centers, hospitals, and clinics. Use scenarios: Classroom anatomy demonstrations in medical education to illustrate the nasal cavity, oral cavity, pharynx and larynx and their interconnections. Patient or student education in clinical settings to explain conditions such as rhinitis, polyps, and tonsillitis. Research and training in ENT anatomy and pathology, supporting instructional demonstrations in laboratories or teaching centers.
