A&E – the difference between

In British slang, it is commonly said of an ignorant person that he "doesn't know his arse from his elbow".  However, one would expect medically-trained individuals to have a somewhat more accurate grasp of basic human anatomy.  Sadly, an elderly patient in Queen Elizabeth Hospital recently found herself the victim of incompetent radiology staff who don't appear to know the arse from the other nearby orifice. As one medical specialist drily commented, "it should not have happened because there were usually no difficulties locating the vagina and anus" – something most of us learn quite early in life.
