Mucose is a term generally used in medical parlance to describe the presence of mucus in the body or on the surface of an organ. It is a sticky, viscous fluid secreted by mucous membranes in the body and aids in the defense against harmful bacteria and viruses. There are several alternate words that can be used to denote mucose. These include mucoid, mucinoid, muciniform, viscid, gluelike, and slimy. While these synonyms aren't necessarily used interchangeably, they all denote properties similar to mucose and are aptly used to describe disorders related to mucus production in diverse medical disciplines.
