In medicine, death or decay of the tip or extremity of a body part, especially the nose or fingers.
From Greek 'akron' (tip/extremity) + 'sphakelus' (gangrene), describing tissue death at the extremes of the body.
This gruesome-sounding medical term describes gangrenous necrosis, but it was important to identify which parts of the body were dying first—extremities like fingers lose blood supply most easily, making this observation crucial to survival!
