Bursa
A bursa is a small sac that contains a small amount of fluid. Normally they are almost invisible, but that changes when they become inflamed.
Bursae are found in places where friction occurs. For example, bursae are found between the skin and a bone or between a tendon and a bone. The task of a bursa is to ensure that these structures can glide easily over each other.
There are many bursae in the body, such as in the hip, knee, elbow, and shoulder. Examples of bursae that lie directly under the skin can be found at the front of the knee or the back of the elbow. A bursa that separates the tendon from the bone is found under the roof of the shoulder or at the attachment of the Achilles tendon.
Bursitis
When a bursa becomes inflamed, this is called bursitis. The bursa is painful and swells. Bursitis regularly occurs in the knee and the shoulder.
