🦴 What exactly is der Oberkiefer?

Der Oberkiefer (Latin: Maxilla) refers to the upper part of the human (and animal) jawbone. It is firmly attached to the skull (unlike the movable Unterkiefer or lower jaw) and holds the upper teeth.

📜 Poem about the Oberkiefer

Hoch im Gesicht, fest und stark,
sitzt der Oberkiefer, hält die Mark.
Trägt Zähne weiß in Reih und Glied,
ein Teil des Schädels, wie man sieht.
Er ruht ganz still, bewegt sich nicht,
gibt dem Gesicht sein fest Gewicht.

(High in the face, firm and strong,
sits the upper jaw, holds its ground.
Carries white teeth in row and file,
a part of the skull, as you can see.
It rests quite still, doesn't move around,
gives the face its firm foundation.)

❓ Riddle

Ich bin ein Knochen, oben im Gesicht,
fest verwachsen, beweglich bin ich nicht.
Ich trage Zähne, eine ganze Reih',
mein unterer Nachbar ist beweglich und frei.

Wer bin ich?

(I am a bone, high in the face,
firmly attached, I cannot move from my place.
I carry teeth, a whole row,
my lower neighbor is mobile and free to go.

Who am I?)
