Flashcards in Leg Bones: Tibia and Fibula (right side, anterior view) Deck (15):
Composed of two long bones
Tibia: larger, medial
Fibula: more delicate, lateral
Synovial hinge joint of the knee
Formed btwn the medial and lateral condyles of the femur
Meeting the medial and lateral condyles of the tibia
Medial and Lateral Menisci
Location: located btwn the condyles of the femur and tibia
Function: c-shaped dense fibrous pads, Assists in rotation of the knee and serves to spread synovial fluid within the joint
Location: btwn the tibial condyles
Function: attaches to the cruciate ligaments to provide stability in the knee joint.
Th weight bearing bone of the leg transmitting force btwn the femur and ankle.
Attaches muscles of the leg, it articulates only with the tibia and does not form a joint with the femur.
Tuberosity of the tibia
Location: below the condyles of the tibia,
Function: prominent roughly triagnular, receives the tendon of the quadriceps femoris muscle via the patella ligament.
Crest of the Tibia
Location: sharp anterior border
Function: subcutaneous (Directly below the skin)
Both on the tibia and fibula
Function: attachment for the interosseous membrane, contains oblique fibers, sloping down from the tibia towards the fibula.
Interosseous membrane (function)
Permits attachment of various muscles found in the anterior leg
Head of the fibula
Above the interosseous membrane,
Function: articulates with the lateral condyle of the tibia, form a gliding joint that is strengthened by surrounding ligaments of the kne joint.
Location: distal end of the tibia is expanded to form the prominent
Function: articulates with the talus bone of the ankle. Forms the major segment of the ankle joint
Location: expanded dista end of the fibula
Function: embrace the ankle joint on either side, thereby preventing undesirable side to side movement,
