Lamel (yüzey anatomisi)

Yüzey anatomisinde lamel, ince levha benzeri yapılardır. Genellikle lameller birbirine çok yakındır ve aralarında boşluk vardır. Solunum organı olmalarının yanı sıra, gekoların yüzeydeki besinleri süzerek beslenmesini sağlarlar.^[1]

The gecko’s adhesive structures are made from ß-keratin (modulus of elasticity [approx.] 2 GPa). Such a stiff material is not inherently sticky; however, because of the gecko adhesive’s hierarchical nature and extremely small distal features (spatulae are [approx.] 200 nm in size), the gecko’s foot is able to intimately conform to the surface and generate significant attraction using van der Waals forces.
