The term "synovial tuft" refers to a small, finger-like projection found in the synovial membrane that lines certain joints. The phonetic transcription of this word is /sɪˈnəʊviəl tʌft/. The "s" sound at the beginning is followed by a short "i" and "o" sound, with the stress on the second syllable. The "v" sound in "synovial" is pronounced as a "w" sound, and the "t" at the end of "tuft" is pronounced clearly. Paying attention to proper spelling and pronunciation of medical terms is crucial for effective communication in the healthcare profession.
A synovial tuft refers to a small protrusion or mound-like structure found within the synovial membrane of certain joints in the human body. This encapsulated structure consists of a dense cluster of specialized connective tissue, blood vessels, and nerve endings. Synovial tufts are typically located in close proximity to the articular capsule, where they project into the joint cavity.
The main function of synovial tufts is to support and maintain the integrity of the synovial membrane. This structure plays a crucial role in the production, secretion, and distribution of synovial fluid, the lubricating substance that allows for smooth joint movement. Synovial fluid contributes to joint nutrition, shock absorption, and reducing friction between the articulating surfaces of bones.
Moreover, synovial tufts have a rich blood supply, ensuring proper oxygen and nutrient delivery to the synovial membrane and surrounding tissues. Additionally, they house various sensory nerve endings, which provide proprioceptive feedback and contribute to joint sensation.
Synovial tufts can be especially prominent in certain joints, such as the metacarpophalangeal joint of the thumb or the metatarsophalangeal joint of the big toe. They are frequently associated with joint stability, assisting in the prevention of excessive movement and potential joint dislocation.
In conclusion, synovial tufts are small specialized structures within the synovial membrane that contribute to the production and distribution of synovial fluid, joint stability, and sensory feedback.

The term "synovial tuft" is composed of two words: "synovial" and "tuft".
1. Synovial: The word "synovial" is derived from the Greek word "synoviōn", which means "synovial fluid". It is composed of two parts: "syn-", meaning "together" or "with", and "oviōn", meaning "egg" or "egg yolk". This is because synovial fluid resembles the consistency of egg yolk, providing lubrication to joints.
2. Tuft: The word "tuft" comes from the Old French word "toffe", meaning "tuft of feathers or wool". It originally referred to a clump or cluster of something, usually hair. It is linked to the Latin word "tufa", meaning "a bunch or cluster of hair".
