| anterior tibial bursa | <anatomy> The small bursa between the medial surface of the medial cuneiform bone and the tendon of the tibialis anterior. Synonym: bursa subtendinea musculi tibialis anterioris, anterior tibial bursa. (05 Mar 2000) |
| bicipitoradial bursa | <anatomy> The bursa between the tendon of the biceps brachii muscle and the anterior part of the tuberosity of the radius. Synonym: bursa bicipitoradialis. (05 Mar 2000) |
| Boyer's bursa | <anatomy> A bursa between the posterior surface of the body of the hyoid bone and the thyrohyoid membrane. Synonym: bursa retrohyoidea, Boyer's bursa, bursa of hyoid, subhyoid bursa. (05 Mar 2000) |
| Brodie's bursa | <anatomy> Medial subtendinous bursa of gastrocnemius muscle. Synonym: bursa of semimembranosus. (05 Mar 2000) |
| bursa | <anatomy> A tissue space (fibrous sac) that is lined with synovial membrane (joint tissue) and contains a small quantity of synovial fluid (joint fluid). Bursas are found in between tendon and bone, skin and bone and muscles. They function to facilitate fluid movement. (27 Sep 1997) |
| bursa achillis | An alternate term for bursa of tendo calcaneus. (05 Mar 2000) |
| bursa anserina | <anatomy> The bursa between the tibial collateral ligament of the knee joint and the tendons of the sartorius, gracilis, and semitendinosus muscles. Synonym: bursa anserina, tibial intertendinous bursa. (05 Mar 2000) |
