Quadriceps
Tibia - what are the condyles? Together?
Medial and lateral condyles - tibial plateau
Tibia - what is the eminence?
Intercondylar eminence
Tibia - what are the borders?
Anterior, sharp front - medial - interosseous membrane
What are the notches?
Trochlea notch, part of ankle joint socket
Fibular notch, where fibula sits
Tibia - what is the malleolus?
Medial malleolus
Tibia - what is the line?
What is the surface?
How does it articulate?
Soleal line
Popliteal surface
Superiorly with femur, distally with talus, laterally with fibular
Fibula - position to tibia?
Lateral to tib at bottom, posterolateral at top
Fibula - what are the parts?
Head, neck, shaft, interosseous border, lateral malleolus, superior and inferior tibiofibular joints
Purpose of the fibula?
Increase surface area for muscle attachment - not weight bearing
