Bursa(redirected from infraspinatus bursa)
Also found in: Dictionary, Thesaurus, Medical.
bursa(bûr`sə), closed fibrous sac lined with a smooth membrane, producing a viscous lubricant known as synovial fluid. Bursas are found in regions where muscles or tendons rub against other muscles, tendons, or bones. The bursas function in two ways, lubricating points of friction, and dissipating force by distributing it through a fluid medium. Normally, the bursas produce just enough synovial fluid to reduce friction. However, constant irritation may lead to oversecretion and consequent enlargement of the bursa, a condition known as bursitisbursitis
, acute or chronic inflammation of a bursa, or fluid sac, located close to a joint. In response to irritation or injury the bursa may become inflamed, causing pain, restricting motion, and producing more fluid than can be absorbed readily.

Bursa was founded in the early second century B.C. by the King of Bithynia, Prusias II, under the name Prusa. It became part of the Roman Empire and later of Byzantium. In 1326, after a ten-year seige, it was conquered by the Ottoman Turks and became the first capital of the Ottoman state. It retained its importance as one of the main cities of Turkey after the capital was transferred to Edirne (1365, by other data 1402) and later Istanbul (1453).
The present-day regular layout of the city took shape during the second half of the 19th century, coming to include the old center of Bursa with its stone two-story houses and its parks, gardens, and architectural monuments—the mosques of Orhan (1304-1417), Ulu Cami (the Great Mosque, 1396-1400), Murad II (1424-27), Yesşil Cami (the Green Mosque, 1424), the Yesşil Türbe mausoleum (1420-21), and a military hospital (1394).
