The vertebrae support the body and protect the spinal cord. They consist of: cervical vertebrae in the neck, thoracic vertebrae in the chest region which articulate with the ribs, lumbar vertebrae in the loin region, sacral vertebrae fused to the pelvis to form the sacrum and tail or coccygeal vertebrae.

The lateral collateral ligament is on the lateral side of the knee and spans from the lateral side of the femur to the head of the fibula. Acting via the patella and patellar ligament, the quadriceps is a powerful muscle that extends the leg at the knee and provides support and stabilization for the knee joint.
