Labels from top to bottom (matching boxes on image):
- Top Left Box: Lateral condyle
- Top Right Box: Medial condyle
- Middle Box: Tibial tuberosity
- Lower Middle Shaft: Anterior border
- Bottom Box: Medial malleolus
Image 2: Tibia and Fibula – Art-labeling Activity 8
Labels (from top to bottom and left to right):
- Topmost structure between tibia and fibula: Superior tibiofibular joint
- Top of tibia center: Intercondylar eminence
- Top of fibula: Head of fibula
- Left shaft (larger bone): Shaft of tibia
- Right shaft (slimmer bone): Shaft of fibula
- Bottom end of fibula (outer ankle bump): Lateral malleolus
- Bottom end of tibia (inner ankle bump): Medial malleolus
- Lower side of tibia where fibula connects: Inferior tibiofibular joint
- Bottom surface of tibia (joins with talus): Articular surface of the lateral condyle
Explanation
The tibia and fibula are the two bones of the lower leg. The tibia, or shinbone, is the larger, weight-bearing bone located medially. The fibula is thinner and located laterally, providing structural support and muscle attachment rather than weight-bearing function.
The lateral condyle and medial condyle are found at the proximal end of the tibia and articulate with the femur to form part of the knee joint. Between them lies the intercondylar eminence, which provides attachment for cruciate ligaments. Just below the condyles on the anterior side is the tibial tuberosity, a prominent bump where the patellar ligament attaches. Running down the anterior side is the anterior border, a sharp ridge palpable through the skin.
At the distal end of the tibia is the medial malleolus, forming the inner bump of the ankle. The fibula ends distally in the lateral malleolus, which forms the outer ankle. These malleoli help stabilize the ankle joint.
The superior tibiofibular joint connects the head of the fibula with the lateral side of the tibia, while the inferior tibiofibular joint does the same distally. The shaft of the tibia and shaft of the fibula form the long central portions of each bone.
Finally, the articular surface of the lateral condyle refers to the surface on the tibia that interacts with the lateral femoral condyle, allowing smooth knee movement. Understanding these anatomical landmarks is crucial for studying lower limb function, joint mechanics, and injury diagnosis.
