What is the etymology of medical term polyp?

The term "polyp" is derived from the Greek word "polypus," which means "many feet" or "octopus." This term was originally used to describe the fleshy growths that occur in the nasal passages, which resemble the tentacles of an octopus. Over time, the term "polyp" came to be used more generally to refer to any type of fleshy growth that projects from a mucous membrane.
