bursa

Examples of bursa in the following topics:

• Bursae and Tendon Sheaths

  • Joints are cushioned by small fluid-filled sacs called bursae and stabilized by tough bands of fibrous connective tissue called tendons.
  • A bursa (plural bursae) is a small fluid-filled sac lined by synovial membrane with an inner capillary layer of fluid (synovial fluid) with the consistency of a raw egg white.
  • Bursae occur at sites of shearing in subcutaneous tissue or between deeper tissues such as muscle groups and fascia.
  • Many bursae develop during growth but new or adventitious bursae can occur at sites of occupational friction.
  • Bursae are found around most major joints of the body such as the shoulder and the knee.

• Bursitis

  • Bursitis is the inflammation of one or more bursae (small sacs) of synovial fluid in the body .
  • The bursae rest at the points where muscles and tendons slide across bone.
  • The bursa and the surrounding joint become stiff the next morning.
  • Bursae that are infected require further investigation and antibiotic therapy.
  • In a bursectomy, the bursa is cut out either endoscopically or with open surgery.

• Overview of the Musculoskeletal System

  • Also made of fibrous tissue are bursae.

• The Peritoneum

  • The second is the lesser sac or omental bursa, and is represented in blue in the image.
  • The epiploic foramen, greater sac or general cavity (red) and lesser sac, or omental bursa (blue).

• Pharynx

  • Superior to the pharyngeal tonsil, in the midline, an irregular flask-shaped depression of the mucous membrane sometimes extends upward; it is known as the pharyngeal bursa.

• Impingement Syndrome

  • Inflammation and subsequent thickening of the subacromial bursa may also cause impingement.

• Structure of Synovial Joints

• Pharynx

  • Above the adenoid, in the midline, is an irregular flask-shaped depression of the mucous membrane called the pharyngeal bursa.
