The neck or a neck-like part of an organism, especially in anatomical or botanical contexts.
From Latin 'collum' (neck), related to the root found in 'collar.' This anatomical term was borrowed directly from Latin and has remained relatively unchanged in scientific nomenclature for centuries.
In botany, the 'collum' is the narrow part where a plant's stem meets the root, and in zoology it describes narrow connecting regions—it's one of those Latin terms that scientists love because it's both precise and elegantly brief.
