Tendons and Bursae

By Alexandra Villa-Forte, MD, MPH, Staff Physician, Center for Vasculitis Care and Research, Department of Rheumatic and Immunologic Diseases, Cleveland Clinic

Take our short survey

Tendons are tough bands of connective tissue made up mostly of a rigid protein called collagen. Tendons firmly attach each end of a muscle to a bone. They are often located within sheaths, which are lubricated to allow the tendons to move without friction.

Bursae are small fluid-filled sacs that can lie under a tendon, cushioning the tendon and protecting it from injury. Bursae also provide extra cushioning to adjacent structures that otherwise might rub against each other, causing wear and tear—for example, between a bone and a ligament or a bony prominence and overlying skin (such as in the elbow, kneecap, or shoulder area).
