How much do you know about the quadriceps muscle?

• The quadriceps femoris is the largest muscle in the body.
• It is three times stronger than its antagonistic muscle, hamstrings.
• The tendons of the four parts of the quadriceps unite to form a single, strong, broad quadriceps tendon.
• The quadriceps tendon is attached to the tibial tuberosity via the ligamentum patellae.
• The patella is embedded in the quadriceps tendon and is the largest sesamoid bone in the body.
• The medial and lateral vast muscles attach independently to the patella and form aponeuroses.
• The aponeuroses reinforce the joint capsule of the knee joint on each side of the patella.
• The rectus femoris is the only part of the quadriceps that crosses the hip joint and is capable of flexing the hip.
