What does the tibial plateau articulate with? | femur |
Rough-textured prominence located on the midanterior surface of the proximal tibia | tibial tuberosity |
Sharp ridge along the anterior surface of the tibia | anterior crest or border (shin) |
Short pyramid process on the distal end of the tibia | medial malleolus |
The lateral aspect of the tibia forms a flattened, triangular shaped structure called... | fibular notch |
What bones does the fibula articulate? | the tibia proximally and the tibia and talus distally |
The head of the fibula is distal or proximal | proximal |
