Bursa mucosa is a medical term that refers to the synovial fluid-filled sac that cushions and lubricates joints. Its correct spelling can be explained using International Phonetic Alphabet transcription as /ˈbɜːsə mjuːˈkoʊsə/. The first part of the word, "bursa", is pronounced with a short "e" sound, followed by an "s" and "a" pronounced separately. "Mucosa" begins with a "m" sound, followed by the long "u" sound and ending with "ko-sa". Proper spelling of medical terms is crucial to avoid confusion and ensure precise communication among healthcare professionals.
The term "bursa mucosa" refers to an anatomical structure present in the body, specifically in certain joints. A bursa mucosa, also known as a synovial bursa, is an elongated sac-like structure lined with a mucous membrane, commonly found near synovial joints such as the knee, elbow, shoulder, or hip. The primary function of a bursa mucosa is to reduce friction and facilitate smooth movement between a bone and a tendon, muscle, or skin.
The inner lining of a bursa mucosa secretes synovial fluid, a viscous fluid that lubricates the joint, enhancing its mobility and reducing wear on the bones and tissues. This fluid helps to minimize the effects of friction and absorb shock during movement, protecting the joint from excessive stress and damage.
Bursae mucosae usually contain a minimal amount of synovial fluid when a joint is at rest. However, during joint movement, the bursa mucosa expands, permitting synovial fluid to flow into its cavity, thereby increasing lubrication and reducing pressure on the joint structures.
Inflammation of a bursa mucosa, known as bursitis, can occur due to trauma, repetitive motion, or underlying medical conditions. Bursitis can cause pain, swelling, and restricted movement in the affected joint.
Overall, the bursa mucosa plays a vital role in maintaining joint health and facilitating smooth movement by reducing friction and providing lubrication between structures within synovial joints.
B. Synovialis, a pouch, containing a viscid fluid, covering and protecting exposed bony surfaces, or interposed between a tendon and a bone over which it plays; many of these are permanent structures and receive various names, gluteal, plantar, prepatellar, etc., to indicate their location.

The word "bursa" in Latin means "purse" or "bag". It originally referred to a small bag that was used to carry money or personal belongings. In medical terminology, the word "bursa" is used to describe a small sac in the body that is filled with synovial fluid and serves as a cushion between bones, tendons, and muscles to reduce friction.
The term "mucosa" refers to the moist lining of some organs and body cavities that secrete mucus. It comes from the Latin word "mucosus", meaning "full of mucus".
Therefore, the term "bursa mucosa" combines the words "bursa" and "mucosa" and is used to describe a bursa sac that is lined with a mucous membrane.
