The fibula:
(a) Forms an important part of the knee joint
(b) Articulates with the femur
(c) Helps to bear the weight of the body
(d) Provides lateral stability to the ankle
(e) Does a and b

검증된 단계별 안내

Step 1: Understand the anatomy of the fibula. The fibula is the smaller of the two bones in the lower leg, located lateral to the tibia.

Step 2: Recall the function and articulations of the fibula. The fibula does not form part of the knee joint and does not articulate with the femur; instead, it mainly provides support to the ankle.

Step 3: Consider the weight-bearing role. The fibula bears very little weight compared to the tibia, which is the primary weight-bearing bone of the lower leg.

Step 4: Focus on the fibula's role in ankle stability. The fibula provides lateral stability to the ankle by forming the lateral malleolus, which helps stabilize the ankle joint.

Step 5: Based on these points, evaluate each option to determine which statement about the fibula is correct.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Anatomy and Function of the Fibula

The fibula is the smaller of the two bones in the lower leg, located laterally to the tibia. It primarily serves as a site for muscle attachment and provides lateral stability to the ankle, but it does not bear significant body weight.

Knee Joint Structure and Components

The knee joint mainly involves the femur, tibia, and patella. The fibula does not form a direct part of the knee joint or articulate with the femur, but it connects to the tibia near the knee via the proximal tibiofibular joint.

Role of the Fibula in Weight Bearing and Stability

Unlike the tibia, the fibula does not bear substantial weight from the body. Its main role is to provide lateral stability to the ankle and support muscle attachments, contributing indirectly to leg function and movement.
