I’ve got a treat for you today. Five pelvic and perineal anatomy questions for the basic science student! ¬†Have fun and remember, well I have nothing witty to say actually haha. Did you know that the pelvis used to be called the innominate bone, literally meaning it was called the “no-name” bone. ¬†That’s just a whole level of dumb isn’t it?
