A bursa is present on a limb or at specific areas of the body that generally have limited movement but with pressure against a portion of bone, tendon or ligament. A bursa can also be found in areas to facilitate the gliding action of a tendon.

'''True or natural bursae''' are located in a predictable position and examples include: [[Equine Phalages - Anatomy & Physiology#Distal Interphalangeal/Coffin Joint|navicular bursa]], prepatellar bursa, cunean bursa, bicipital bursa, trochanteric bursa and the subtendinous bursa of the common calcaneal tendon.

'''Acquired bursa''' develop subcutaneously in response to pressure and friction. Tearing of the subcutaneous tissue allows fluid to accumulate and become encapsulated by fibrous tissue. These include: olecranon bursa ('''capped elbow'''), subcutaneous calcaneal bursa ('''capped hock''') and carpal hygroma.
