A bursa (plural bursae) is a small fluid-filled sac lined by synovial membrane with an inner capillary layer of slimy fluid (similar in consistency to that of a raw egg white). It provides a cushion between bones and tendons and/or muscles around a joint. This helps to reduce friction between the bones and allows free movement. Bursae are filled with synovial fluid and are found around most major joints of the body.
Bursa is Latin for purse, due to its resemblance to a purse. There are different types of bursa. Bursae is its plural form.
There are four types of Bursa namely adventitious, subcutaneous, synovial, and Sub muscular. Among these, only Adventitious is non-native. When any surface of the body is subjected to repeated stress, an adventitious bursa develops under it. Example: Students elbow, bunion.
Infection or irritation of a bursa leads to bursitis (inflammation of a bursa). The general term for disease of bursae is "bursopathy". Current medical studies have no specific knowledge of the entire bursae system.
Bursa (Turkish pronunciation: [ˈbuɾsa]) is a city in northwestern Turkey and the seat of Bursa Province. The metropolitan area in the entire Bursa province had a population of 2.6 million as of 2010, making the city the fourth most populous in Turkey. The city is equally one of the most industrialized metropolitan centers in the country.
Bursa was the capital of the Ottoman State between 1326 and 1365. The city was referred to as "Hüdavendigar" (meaning "God's Gift") during the Ottoman period, while a more recent nickname is "Yeşil Bursa" (meaning "Green Bursa") in reference to the parks and gardens located across its urban tissue, as well as to the vast forests in rich variety that extend in the surrounding region. The city is synonymous with Mount Uludağ which towers behind its core and which is also a famous ski resort. The mausoleums of the early Ottoman sultans are located in Bursa and the numerous edifices built throughout the Ottoman period constitute the city's main landmarks. The surrounding fertile plain, its thermal baths, several interesting museums, notably a rich museum of archaeology, and a rather orderly urban growth are further principal elements that complete Bursa's overall picture.
