Bursa, city, Turkey

Bursa (brsä`), city (1990 pop. 838,323), capital of Bursa prov., NW Turkey. The market center of a rich agricultural region, on the ancient Silk Road S of Constantinople, Bursa was long noted for its silks, but is now a producer of automobiles, other textiles and apparel, and metals. Founded at the end of the 3d cent. B.C. by the king of Bithynia, Prusias I, it was called Prusia ad Olympium or Prusa. It was captured by the Seljuk Turks in 1075, taken by the Crusaders in 1096, and in 1204 passed to the Byzantines. Captured in 1326 by the Ottoman Turks, it became the Ottoman capital. It was sacked by Timur in 1402; afterward Adrianople (now Edirne) became (1413) the new Ottoman capital. Among the city's sites, the Green Mosque (1421) and mosque of Beyazid I (1399) are especially noted. The town is sometimes called Brusa.

bursa, in anatomy

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 bursitis. In the hand and foot, the bursa assumes a tubular form. Called the synovial sheath, the structure encloses the tendons along their entire length.

Bursa

 formerly Brusa ancient Prusa

City (pop., 1997: 1,066,559), northwestern Turkey. It was founded in the 3rd century BC, at the foot of the Mysian Mount Olympus near the southeastern shore of the Sea of Marmara, as the seat of the kings of Bithynia. It flourished under the Romans (see Roman Republic and Empire) and later under the Byzantine Empire. After Crusaders conquered Constantinople (modern Istanbul) in 1204, it was a seat of Byzantine resistance. The Ottoman Empire took it in the early 14th century and made it their first great capital. Conquered by Timur in the early 15th century, it was later recovered by the Ottomans. Though the Ottoman capital was later moved to Constantinople, Bursa continued to prosper. Under the Republic of Turkey, it is a centre for agriculture and is noted for its carpets and many 15th-century mosques.
