retikkel

Retikkel is a Norwegian term used to denote a net-like or grid-like structure across several disciplines. It derives from Latin reticulum, meaning a small net, and is applied in contexts where a mesh, lattice, or branching network is involved.

In biology and anatomy, retikkel commonly refers to reticulum, a membranous network within cells such as the endoplasmic reticulum (ER). The ER forms a continuous system of tubules and sacs involved in protein and lipid synthesis and transport. In tissue anatomy, reticular tissue (retikulært vev) is a loose connective tissue that provides a supportive mesh for organs like the spleen, lymph nodes, and bone marrow. This framework is made largely of reticular fibers, which are thin type III collagen fibers produced by reticular cells.

In immunology and histology, reticular networks organize and support immune cells, forming the scaffolding that facilitates filtration and cell interactions in lymphoid organs.

In optics and measurement, retikkel refers to the reticle—the grid or crosshair in sighting devices, scopes, or microscopes used for aiming, alignment, or precise measurement.

In botany and zoology, the term appears in descriptions of net-like patterns, such as reticulate venation in leaves or other netted morphological patterns.

Overall, retikkel denotes a networked or mesh-like arrangement that imparts structure, organization, or alignment in its respective field. The term is used across disciplines to emphasize the interconnected, net-like nature of a component or system.
