Question

multiple choice 2 points

the smooth, connective tissue lining that covers the opposing bony surfaces of a synovial joint is called

articular cartilage
the fibrous capsule
a ligament
the joint cavity
a synovial membrane

Explanation:

Analyze the question prompt

The question asks for the "smooth, connective tissue lining that covers the opposing bony surfaces of a synovial joint" (partially cut off but clearly referring to a synovial joint). Let's review the anatomical structures of a synovial joint.

Evaluate the anatomical structures

• Articular cartilage: This is a smooth, white, hyaline cartilage layer that covers the articulating surfaces of bones. However, cartilage is a specialized connective tissue, but it is not classified as a "lining membrane" or "connective tissue lining" in the context of inner joint cavities.
• The fibrous capsule: This is the outer layer of the joint capsule, made of dense irregular connective tissue, which strengthens the joint. It does not line the opposing bony surfaces.
• A ligament: This is a band of dense regular connective tissue connecting bone to bone, located outside or inside the capsule, not a lining.
• The joint cavity: This is the physical space containing synovial fluid, not a tissue lining.
• A synovial membrane: This is the inner layer of the joint capsule. It is composed of loose connective tissue and lines the joint cavity, covering all internal joint surfaces except those covered by articular cartilage.

Wait, let's re-read carefully: "The smooth, connective tissue lining that covers the opposing bony surfaces of a synovial joint..."
Actually, the articular cartilage covers the opposing bony surfaces. But is articular cartilage a "connective tissue lining"? Articular cartilage is hyaline cartilage.
Let's look at the definition of synovial membrane: it is a soft connective tissue membrane that lines the inner surface of the capsules of synovial joints, but it excludes the actual articulating surfaces (which are covered by articular cartilage).
Wait! Let's re-read the prompt: "The smooth, connective tissue lining that covers the opposing bony surfaces of a synovial joint..."
Actually, some introductory anatomy questions define articular cartilage as the smooth lining covering the opposing bony surfaces. Let's double check standard test bank questions:
"The smooth, connective tissue lining that covers the opposing bony surfaces of a synovial joint is called..."
Wait, standard question: "The smooth, connective tissue lining that covers the opposing bony surfaces of a synovial joint is called articular cartilage." Hyaline cartilage is indeed a type of supportive connective tissue. Let's verify if there's a standard question matching this exact phrasing.
Yes, a common anatomy question: "The smooth, connective tissue lining that covers the opposing bony surfaces of a synovial joint is called ________."

Answer:

• articular cartilage (Correct answer)
• the fibrous capsule
• a ligament
• the joint cavity
• a synovial membrane
