Material Size: Made of environmentally friendly PVC material, beautifully handpainted, odor, corrosionresistant, lightweight, and strength. Size: 12 x 12 x 23 cm (1:1 adult size). 3. Efficient teaching aid: Features a variety of textures, is resistant to bending, and has an irregular skin texture on the surface. intuitive, ideal for teachers to explain concepts to students, making technical knowledge easier to understand and more engaging. Helps capture students' attention and lays a solid foundation for future learning. 4. Detailed display: The posterior pharyngeal cutout highlights the most common site for nasopharyngeal . The oropharynx is located between the soft palate and the upper edge of the epiglottis and connects to the oral cavity through the pharyngeal isthmus in the front. The side wall accommodates the palatine tonsils.
