Synovial bursa
Synovial Bursa
Synovial bursa (pronunciation: /sɪˈnoʊviəl ˈbɜːrsə/) is a small fluid-filled sac lined by synovial membrane with an inner capillary layer of viscous synovial 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 found around most major joints of the body.
Etymology
The term "synovial bursa" is derived from the Greek word synovia meaning "like an egg," and the Latin word bursa meaning "purse." The term is used in anatomy to describe a structure that is similar to a small fluid-filled sac or purse.
