Q

bags of synovial fluid that acts as lubricating “ball bearings,” reduces friction where ligaments, muscles, skin, tendons, or bones rub together

Q

What are the factors that influence stability of synovial joints?

A

shape of articular surface (shallow surfaces less stable than ball and socket), ligament number/location (more ligaments –> stronger joints), muscle tone keeps tendons taut as they cross joints (important in shoulder and knee)

largest, most complex joint, consists of 3 joints surround by a single cavity (femoropatellar joint, lateral joint, medial joint)

A

knee

44
Q
