Durchtrennung

Durchtrennung is a German term meaning the act of cutting completely through a structure, resulting in separation of its parts. Derived from durch (through) and trennen (to separate), it is used mainly in medicine, biology, anatomy, and botany to describe transection or dissection where a structure is severed along its axis or across it.

In medicine and surgery, Durchtrennung denotes intentional cutting through tissue, such as transection of a nerve, a spinal cord, a duct, or a vessel. The procedure is performed for diagnostic, therapeutic, or experimental purposes and is associated with functional impairment depending on the structure involved. In neuroscience, nerve transection is used to study pathways or to treat conditions by disrupting problematic connections, though it carries risks including loss of sensation or motor function. In surgical contexts, transection may be a step in resection, exposure, or bypass procedures.

In biology and botany, Durchtrennung can refer to dissection of specimens to study anatomy or histology, and to transection of plants for grafting or analysis of internal structures. It is distinct from partial incisions or superficial cuts in that the entire structure is cut through. The term is used primarily in German-language texts and often appears alongside the loanword transection in English, sometimes as a direct translation. See also: transection, dissection, resection.
