The epiphyses of a long bone are covered by the ______.Multiple choice question.yellow marrowarticular cartilageendosteumcanaliculus

Step 1: Break Down the Problem

We need to determine what covers the epiphyses of a long bone from the given multiple choice options.

Step 2: Relevant Concepts

• Epiphyses: The ends of long bones, which articulate with adjacent bones.
• Articular Cartilage: It is a smooth, white tissue that covers the ends of bones in joints.

Step 3: Analysis and Detail

1. Yellow Marrow: This is found in the medullary cavity of long bones, not covering the epiphyses.
2. Articular Cartilage: This type of cartilage is located at the surface of the epiphyses where joints are formed, providing cushioning and reducing friction.
3. Endosteum: This is the thin membrane lining the medullary cavity, but it does not cover the epiphyseal surfaces.
4. Canaliculus: This refers to small channels in bone through which bone cells communicate, but is not a covering.

Step 4: Verify and Summarize

Among the provided options, the term that best describes what covers the epiphyses of a long bone is articular cartilage.

Final Answer

Articular cartilage.
