Best Answer

A bursa is a sac filled with fluid to protect the tendons (plural bursae).

A bursa is an expansion of synovial membrane that is found at sites of potential friction, ie. between your Achilles tendon and your calcaneus (heel bone).

Bursae are lubricated on their inner walls by synovial fluid. By rolling between two structures, bursae keep friction to a minimum and prevent damage.
