bursae
Fluid-filled pouches
Bursae is the plural of bursa, a small fluid-filled sac that cushions bones, tendons, and muscles near joints.
These anatomical structures reduce friction during movement: The bursae in her knee became inflamed from repetitive kneeling.
When bursae swell or irritate, the condition is called bursitis.
