Notes on Meaning

The word "funiculus" is highly specialized. Its meaning is entirely dependent on the scientific context: - In anatomy/zoology, it refers to a small, cord-like bundle of fibers (e.g., nerve fibers). - In botany, it refers specifically to the seed stalk. These two meanings are distinct and not interchangeable within their respective fields.

Noun
