I´se sorry MR. HUNT but this sheath o' yours ain´t no bursa. It be nothin' other than a fascia. Fasciae (divided into superficial fascia and deep fascia) hold muscles together in bundles and on a smaller scale, the deep fascia forms the epimysium, perimysium, and endomysium, respectively, that join at the end of a muscle to form a T-E-N-D-O-N. A bursa is a sheath around a synovial cavity which, in turn, contains synovial fluid. Your description of the "fascia", meaning "bandage", is wrongly intertwined with the "bursa" (meaning "pouch", or in French "bank" "bourse") and intermingling use of these terms can be dangerous e.g. "Intern, remove this bursa"..."What the hell did you do?"..."I removed the bursa"... Don´t mix up your anatomy and leave this to the pre-senile ones! Kristinn Leifsson, Reykjavík, Iceland Bursitis is an inflammation of the bursa, the sheath holding >muscles in bundles. > Newton
