Definition
  1. Noun (plural of ):
    • Thin layers or plates: "lamellae" are thin, flat, scale-like structures or layers, often found in biological, geological, or material contexts. They are typically arranged in parallel or overlapping patterns.
    • Botanical structure: In plants, "lamellae" refer to the thin layers of tissue within a leaf or other organ, such as the middle lamella that cements plant cells together.
    • Zoological structure: In animals, "lamellae" are thin, plate-like structures, such as the gill lamellae in fish or the lamellae in the inner ear (e.g., the lamellae of the cochlea).
    • Mineralogical sense: In geology, "lamellae" are thin, flat layers within minerals or rocks, such as those seen in the cleavage of mica.
Usage Examples
  • (Thin, plate-like structures in gills.)
  • (Thin layers of plant tissue.)
  • (Flat layers in a mineral.)
Advanced Usage

  • "Basal lamellae": In biology, a specialized layer of extracellular matrix that supports epithelial cells.

    • The basal lamellae separate the epithelium from underlying connective tissue. (Structural support layers.)

  • "Cement lamellae": In dentistry, thin layers of cementum that cover the roots of teeth.

    • The cement lamellae help anchor the tooth to the jawbone. (Protective dental layers.)

    • Each lamella is only a few micrometers thick. (One individual layer.)

  • Lamellar (adj): relating to or consisting of lamellae.

Synonyms
  • Plates: flat, thin pieces of material.
  • Layers: sheets or strata that are stacked.
  • Scales: thin, overlapping pieces (often used for fish or reptiles).
  • Folia: plural of , meaning thin, leaf-like layers (used in biology and geology).
