Quadriceps
The quadriceps femoris muscle, also called the quadriceps extensor, quadriceps or quads is a large muscle group that includes four large muscles on the front of the thigh. These are the only muscles in the human body that can extend the knee.
Structure
[change | change source]Parts
[change | change source]The Quadriceps are divided into four different muscles, also called the 'heads'[1][2]
- The rectus femoris muscle is located in the middle of the thigh, covering most of the other three quadriceps muscles.[1] It originates from the hip bone. It is named for its straight course.
- The vastus lateralis muscle is on the outer side of the thigh.[1]
- The vastus medialis muscle is on the inner part of the thigh.[1]
- The vastus intermedius muscle lies between vastus lateralis and vastus medialis on the front of the femur, but deeper than the rectus femoris muscle.[1]
