Beats approximately 100,000 times per day, pumping about 7,500 liters of blood daily. | The most powerful extensor of the knee joint. Essential for standing, walking, climbing stairs, and running. The rectus femoris also flexes the hip. |
| Clinical Significance | Coronary artery disease is the leading cause of death worldwide. Myocardial infarction results from coronary artery occlusion. Heart failure, valvular diseases, arrhythmias, and congenital heart defects are major cardiovascular conditions. | Quadriceps tendon rupture prevents active knee extension. Vastus medialis oblique weakness contributes to patellar maltracking. Quadriceps atrophy commonly follows knee injuries and surgeries. |
