true
True or false: synovial capsules are not covered in a fibrous capsule?
false… they ARE covered in a fibrous capsule
true or false: synovial joints are enclosed by ligaments for stability?
this is TRUE! strength is gained from these ligaments
true or false: synovial joint capsules are not lined by a synovia membrane that secretes synovial fluid for lubrication?
