Q

Ægte led

A

Led med en ledhule med væske. Der er ledbrusk på ledfladerne og en ledkapsel der består af to lag – yderst den fibrøse kapsel og inderst den synoviale membran – der laver ledvæske. Der kan være en bruskskive inde i leddet – der deler ledhueln i to kamre. Bruskskiven hedder en discus articularis – og findes fx i kæbeleddet.
