Lamellenartig

Lamellenartig is an adjective used to describe structures that are composed of or arranged in thin plate-like elements called lamellae. The term derives from Lamelle in German, which itself goes back to French lamelle and Latin lamella. It is a descriptive, cross-disciplinary term and does not denote a specific process or category on its own.

In biology the expression is used for tissue or structural organization that shows layered, plate-like geometry. A classic example is lamellar bone, in which collagen fibers and mineral deposits form a regular series of concentric or parallel layers. This contrasts with woven bone, where fibers are more randomly oriented. Lamellar patterns can also be observed in dentin and other tissues where a similar layered arrangement exists.

In geology and materials science lamellenartige textures arise when thin layers are deposited or arranged parallel to one another. Such lamellar structures contribute to anisotropic mechanical properties and can improve toughness in laminated rocks or in engineered composites. Biomimetic approaches frequently aim to reproduce lamellar architectures, as in nacre-like ceramics or metal–ceramic laminates, to combine lightness with strength and damage tolerance.

In microscopy and anatomy the term is used to describe appearances where surfaces or cross-sections reveal plate-like divisions rather than fibrous or granular textures. Lamellenartig emphasizes the presence of layering and plate-like organization across scales, from cellular to macroscopic.

Overall, lamellenartig is a qualitative descriptor that signals a plate-like, layered arrangement of components, rather than a defined structural category.
