In biology: a ‘raphe’ is a longitudinal seam that usually indicates some sort of mid-line.

There’s one in the medulla oblongata as well as one running from the anus through the mid-line of human genitalia. (pictured above you can see the perineal raphe.)

It is thought that the biblical account of creation where God removes a rib from Adam to make Eve is actually an errant translation and that the actual meaning was something closer to a reference to the fact that unlike most placental mammals, humans do not have baculum. (The folk wisdom is that since god took the bone from Adam and used it to make eve; the raphe is less seam and more vestigial scar tissue.)
