Definition (FMA) Transudate contained in the synovial cavity of joints, and in the cavity of tendon sheaths and bursae.
Definition (MSHCZE) Kloubní maz. Viskózní tekutina, která má význam pro vzájemný pohyb kloubních ploch a omezení jejich tření. Je produkována synoviální blankou (membrana synovialis, zkráceně synovialis), která tvoří součást výstelky kloubu (vnitřní vrstva kloubního pouzdra). Její vlastnosti se mění u některých kloubních onemocnění. V některých případech se s. blanka chirurgicky odstraňuje (synovektomie). Ve složení se uplatňují některé mukopolysacharidy, např. hyaluronová kyselina, která se rovněž dodává jako lék. (cit. Velký lékařský slovník online, 2012 http://lekarske.slovniky.cz/ )
