True about synol membrane of knee joint is: (A) Invaginated posteriorly by cruciate ligament, (B) Extension into prepatellar bursa, (C) Covers inferior surface of both menisci, (D) Extension into infrapatellar bursa
Answer is A. A. i.e. Invaginated posteriorly by cruciate ligament Synol membrane reflects from posterior aspect of joint on to the cruciate ligaments (ant. & post.) making them extrasynol structuresQFour bursae communicate with the synol cavity of knee joint - suprapatellar bursa, popliteal bursa, anserine (semimembranosus) bursa & gastrocnemius bursa.QCruciate ligaments are intraicular (or intracapsular) but extra synolQ structures.Menisci are intraicular (capsular) & intrasynol structures but its surface has no synol coveringQ. It's upper surface are in contact with femoral condyle & lower surface with tibial condyle.
