What is the Quadriceps Femoris?
The quadriceps femoris is a group of four muscles on the front of your thigh. People often call it “the quads.” It starts from your pelvis and the upper part of your thigh bone, then runs down to your knee and attaches through the quadriceps tendon to your kneecap, and from there through the patellar tendon to the top of your shin bone. Because of that setup, it’s one of the main muscle groups that straightens your knee and helps control your knee when you bend it.
