What is the name of the muscle on the top front of your leg?

also could you help me with this question too?

What is the name of the muscle on the back of your upper leg?
Answer:
The quadriceps femoris (a.k.a. "quads") is a group of four muscles covering the femur bone of the thigh. The first muscle group of the quad is the vastus lateralis, which is found on the outer part of your upper leg often called the quad sweep. The vastus medialis lies on the inside of you upper leg forming a teardrop just above your knee. The vastus intermedius is found on the top part of the femur and is also located deep into the lateralis and medialis muscle groups. Making up the fourth muscle group of the quad, the rectus femoris runs from the hip bones (the iliac crest) all the way down to the knee (platella). All of these four muscles (vastus and the rectus femoris) are responsible for extending the leg at the knee.

The back of the upper leg is comprised of three hamstring muscles. The muscle we sit on is called the biceps femoris and has both a long head near the hip (ischial bone) and a short head above the back of the knee that connects to a tendon which connects to the fibula. The inside-back of the thighs are comprised of the semitendinosus and semimembranosus muscles. Sound like a mouthful? Well, they both connect between the hip and the tibia bone of the lower leg. Lastly and certainly not the least important, the gluteus maximus ("glutes") is the largest and thickest hip muscle and consists of the thickest and strongest fibers in the body. These muscles pull the thigh and lower leg backward like that of a thigh extension (pulling your heel to your butt).

The front is your quadrisceps I think and the back are your hamstrings. If not, then vice-versa.

The front is the quadriceps and the back is, I have no idea. I hope this helps.
