to protect the tendon from wear and tear in physical movement, like when you exercise.
bursae and tendon sheaths he;p to reduce friction during joint movement
Yes, tendon sheaths do act as friction reducing structures within the body. Tendon sheaths generally are found in areas where the tendons are constantly under pressure do to motion.
bursae are flattened fibrous sacs, while tendon sheaths are elongated fibrous sacs.

The membrane type that is in joints, bursae and tendon sheaths is described as synovial. Synovial membrane is also referred to as stratum synoviale.
Synovial membranes.
They act as "ball bearings" to reduce friction between bones. Bursae are flattened fibrous sacs lined with synovial membrane and are commonly found where ligaments, muscles, bones, or tendon rub together. A tendon sheath is essential an elongated Bursae that completely wraps around tendons subjected to friction.
The difference between a bursa and a tendon is that a bursa is a synovial pocket insterted between a tendon and a bony prominance. It is not bound by a deep fascia or retinaculum. So from top to bottom a visual would be (tendon, synovial fluid, bone). A tendon synovial sheath, on the other hand, is bound by a deep facia or retinaculum and the synovial fluid almost completely surrounds the tendon with the exception of a small gap called the mesotendon.
Balls
Yes. tendon connects bone to muscles.
The synovial membrane is found on the cavities of joints, tendon sheaths and bursae. It is a layer of connective tissue that makes the synovial fluid, which is used for lubrication.
No, a tendon attaches a muscle to bone. A ligament attaches a bone to another bone.
