Female Pelvic Skeleton with genitalia, 3 parts. This natural casting of the female bony pelvis, complete with the 4th and 5th lumbar vertebrae, sacrum and coccyx, has been fitted with external and internal genitalia, perineum, rectum, anus and bladder to illustrate their relationship to the underlying bony framework. All soft tissue structures have been molded of resilient soft vinyl. For complete visibility, the bladder and a portion of the uterus with one fallopian tube and ovary can be detached. Mounted on a rectangular base, the three-part model measures 13×10×7 inches (33×26×18cm).
