Vesikulärer

Vesikulärer is an adjective of German origin meaning vesicular in English. It describes something relating to or consisting of vesicles—small sacs or cavities bounded by membranes.

In biology and medicine, vesikulär is used to denote structures or processes involving vesicles. Vesicles are intracellular or extracellular sacs that transport, store, or release substances. The term appears in discussions of vesicular transport, a cellular system that moves proteins and lipids between organelles (such as the endoplasmic reticulum, Golgi apparatus, and plasma membrane) via membrane-bound vesicles. In clinical settings, vesikuläre Läsionen or vesicular lesions refer to small fluid-filled blisters on the skin or mucous membranes. Vesicular diseases, such as vesicular stomatitis in animals, are characterized by the formation of these vesicles and associated symptoms.

In geology and petrology, vesikulär describes igneous rocks that contain vesicles—cavities formed by gas bubbles trapped during solidification. Vesiculated textures are common in volcanic rocks like basalt and andesite and can influence porosity and rock strength.

Etymology and scope: vesicula is Latin for a small vessel, giving rise to vesicle and vesicular in scientific terminology. While the term is most frequently encountered in biology and geology, vesikulär conveys a general sense of vesicle-related structure or function across disciplines.
