-flattened, fibrous sacs lined with a synovial membrane containing synovial fluid
-commonly found between bone and skin, muscle, ligaments and tendons; they are common where adjacent structures rub together
-act as cushions in places where friction could develop
-ex. in knee

fat pads:
-localized adipose tissue covered with a synovial membrane
-found superficial to the joint capsule
-provides cushioning and packing around a joint; stabilizes the joint
-ex. in knee

menisci: two wedge shaped pieces of meniscal cartilage act as "shock absorbers" between your femur and tibia. Different from articular cartilage, the meniscus is tough and rubbery (fibrocartilage) to help cushion and stabilize the joint. When people talk about torn cartilage in the knee, they are usually referring to torn meniscus

ligaments: bones connected to other bones by ligaments. Strong, tight ligaments and collagen fibers of the joint capsule unite bones; together these fibers prevent excessive undesirable movements
-4 main ligaments in your knee act like strong ropes to hold the bones together and keep your knee stable

Collateral ligaments: on sides of your knee
-medial (tibial) collateral ligament is on the inside of your knee, and the lateral (fibular) collateral ligament is on the outside. They control the sideways motion of your knee and brace it against unusual movement

-cruciate ligaments; these are found inside your knee joint. They cross each other to form an "X" with the anterior cruciate ligament in front and the posterior cruciate ligament in back. The cruciate ligaments control the back and forth motion of your knee
