Question

multiple choice question

synovitis is inflammation of what structure?

a tendon
a joint capsule
synovial fluid

Explanation:

Analyze the medical term

Using the Joint Pathology knowledge point
The term "synovitis" consists of the root word "synovi-" (referring to the synovial membrane or synovium) and the suffix "-itis" (which denotes inflammation).

Identify the affected structure

The synovial membrane is the inner connective tissue layer of the joint capsule that lines the joint cavity and secretes synovial fluid. Therefore, synovitis is specifically the inflammation of this membrane.

Evaluate the given options

• A tendon: Inflammation of a tendon is called tendinitis.
• A joint capsule: While the synovial membrane is part of the joint capsule, synovitis specifically targets the inner synovial membrane lining rather than the entire fibrous capsule. However, in introductory anatomy contexts, the synovial membrane is the primary answer. Let's re-examine the options:
• A tendon
• A joint capsule
• Synovial fluid (fluid itself cannot be inflamed, only tissues can undergo inflammation)
• A synovial membrane (implied correct anatomical target, though cropped or scrollable, "A joint capsule" is the closest structural option if "synovial membrane" is not listed, but let's look at standard anatomical definitions where synovitis is the inflammation of the synovial membrane).

Answer:

• A tendon
• A joint capsule (Correct answer)
• Synovial fluid
