They are called as bursae. They reduce the friction of the muscle tendons.

It is synovial fld that lubricates the joints of bodies.
Synovial fluid is a thick, stringy fluid found in the cavities of synovial joints. With its egg-like consistency (synovial comes from Latin for "egg"), synovial fluid reduces friction between the articular cartilage and other tissues in joints to lubricate and cushion them during movement.
A synovial fluid sac which is actually called a synovial bursa is a fluid-filled sac lined with synovial membrane with an inner layer of slimy fluid. This provides cushion between bones and tendons and/or muscles around joints. They also reduce friction between the bones.
Amount of synovial fluid.
Synovial fluid in the synovial sacs (in bone joints) saves the participating bones in the joints from hurt, injury by acting like pad (buffer) between the articulating bones
Some Synovial joints may have fluid-filled sacs called bursae.
All synovial joints contain a joint cavity. Synovial joints differ from the other joints: Fibrous and cartilaginous joints. Synovial is different because of its structure, and includes several parts including a joint cavity.
Synovial fluid is the fluid found in synovial joints, and is secreted by the synovial membrane. The shoulder, elbow, wrist, hip, knee and ankle are synovial joints, as are metacarpo- and metatarsophalangeal and interphalangeal joints.
Joints may be synovial (with a cavity) or fibrous. Synovial joints are filled with synovial fluid. Fibrous joints lack this. Fibrous joints are found in between the vertebrae. Cartilage in is both joints. This can be hylaine or fibrocartilage. Both regenerate. The synovial fluid is rather slippery and allows easy movement in those joints. If this joint is suddenly and rapidly pulled, the fluid doesn't fill quickly and a "snapping" sound is heard.

The membrane type associated with connective tissue is the synovial membrane. This important membrane type is found in the spaces between bone joints and produces a slippery substance called synovial fluid, which greatly reduces friction when joints move.THERE WILL BE NO MOMENT IF SYNOVIAL FLUID IS ABSENT Synovial fluid lubricates hinge joints (knee, elbow and finger joints) ball-and-socket joints (shoulder, hip) and gliding joints (wrist, ankle). Without it, joints would not move freely and would become arthritic.
All joints have a membrane called the synovial membrane. It contains synovial fluid; therefore, all joints contain a fluid.synovial Joint

Fibrous joints connect bones to minimize movement. The bones of your skull and pelvis are held together by fibrous joints. Cartilaginous joints are joints in which the bones are attached by cartilage. These joints allow for only a little movment, such as in the spine or ribs. Synovial joints allow for much more movement than cartilaginous joints. Cavaties between bones in synovial joints are filled with synovial fluid. This fluid helps lubricate and protect the bones. Bursa sacks contain the synovial fluid.
Synovial cysts are what causes facet fluid in vertebra. Synovial cysts are benign, fluid filled sacs that develop in the facet joints of the lumbar spine as a result of degeneration.
