Von Kopf bis Fuß — from head to toe. Learn each part of the body with its article: you'll need it the moment something hurts.

Start with the head:

German	English
der Kopf	head
das Auge — die Augen	eye — eyes
das Ohr — die Ohren	ear — ears
die Nase	nose
der Mund	mouth
der Zahn — die Zähne	tooth — teeth
der Hals	throat; neck

Der Hals does double duty: it's both your neck and your throat.
