The word 'Musterung' (patterning / medical examination) is derived from 'das Muster' (the pattern / sample). A 'Muster' can be a design (meaning 1) or a test specimen (a 'sample' human is examined, meaning 2).
Das Muster des Teppichs passt gut zur Musterung der Vorhänge.
The pattern of the carpet goes well with the patterning of the curtains.
The two meanings are very different. If it is about fabric, design, animals, or surfaces, it refers to the pattern. If it is about the military, compulsory service, or doctors, it refers to the fitness examination.
Die Schlange hatte eine auffällige, zickzackförmige Musterung.
The snake had a striking zigzag patterning.
For the design meaning, adjectives that describe the pattern are often used, e.g. 'eine feine Musterung' (a fine patterning), 'eine geometrische Musterung' (a geometric patterning), or 'eine natürliche Musterung' (a natural patterning).
Der Schmetterling hat eine wunderschöne Musterung auf den Flügeln.
