| mucous connective tissue | A type of connective tissue little differentiated beyond the mesenchymal stage; its ground substance of glycoproteins is abundant and contains fine collagenous fibres and fibroblasts; in its most characteristic form, it appears in the umbilical cord as Wharton's jelly. Synonym: gelatinous tissue. (05 Mar 2000) |
| mucous cyst | A retention cyst resulting from obstruction in the duct of a mucous gland. Synonym: mucocele. (05 Mar 2000) |
