A. Human pelvic bone model: An anatomically correct, life-size female pelvic model that shows the precise anatomical features of the human female pelvis, including the left and right innominate bones (hip bones), pelvic bones (ischium, ilium, and pubis), sacrum, coccyx, pubic symphysis, acetabulum, and obturator foramen. The pubic symphysis has a "cartilage" for a highly detailed and realistic appearance. B. Teaching demonstration: It presents the female pelvis in a three - dimensional form for intuitive viewing. It can be used for teaching demonstrations by clinicians and physical therapists specializing in women's health issues. It is helpful for patient education and is a tool for comparing the skeletal anatomy of males and females. C. Knowledge is power: It can be used in the classroom to show the birth canal through which a fetus passes (the canal diameter is approximately 4 inches/10.2 cm; it is fixed and non - elastic). Students can use the model for study at home without having to go to the library late at night. D. Close - up observation: The model can be carefully observed from all angles. The overall size of this human skeletal model is life - sized. The model is pre - assembled, and disassembly is not recommended. The flexibility of the pelvis can be adjusted by loosening or tightening the screws (removing the screws is not recommended). E. Durable: The model bones are made of polyvinyl chloride (PVC). The pubic symphysis cartilage is made of rubber for realistic demonstrations. The joints are fixed with screws and are immovable. F. Color: As shown in the picture. G. Material: Polyvinyl chloride (PVC). H. Dimensions: 24.5×17×17 cm. I. Package contents: 1 pelvic model. The package only includes the above - mentioned contents and does not include other products. Note: Lighting and different displays may cause slight differences between the color of the items in the picture and the actual product. A measurement error of ±1 - 3 cm is allowed.
