What are the two smooth, rounded joint surfaces at the distal end of the femur called?Multiple choice question.condylessupracondylar linesepicondyles

Break Down the Problem

1. Identify the key terms related to the anatomy of the femur.
2. Differentiate between the provided options based on anatomical knowledge.

Relevant Concepts

• The femur has specific features at its distal end that articulate with the knee joint, which include particular surfaces and processes.

Analysis and Detail

1. Condyles: The term "condyles" refers to the smooth, rounded ends of the femur that articulate with the tibia. They are crucial for the knee joint's movement.
2. Supracondylar Line: This refers to the lines found above the condyles and does not refer to smooth joint surfaces.
3. Epicondyles: These are bony protrusions above the condyles and are not smooth joint surfaces.

Verify and Summarize

Given the descriptions:

• Condyles are the only option that describes the smooth, rounded joint surfaces.

Final Answer

The correct answer is condyles.
