The back of the leg muscles include the following: *1 pointgluteus maximus, gastrocnemius, hamstrings: semimembranosusDeltoid, trapezius, extensor carpi radialisquadriceps: vastus lateralis, tibialis anterior, fibularis longusFrontalis, Masseter, Buccinator

The muscles located at the back of the leg include the gluteus maximus, gastrocnemius, and the hamstrings, specifically the semimembranosus.

1. The gluteus maximus is the largest muscle in the body and is located in the buttocks. It is responsible for movement of the hip and thigh.

2. The gastrocnemius is one of the calf muscles. It flexes the foot at the ankle joint and flexes the leg at the knee joint.

3. The hamstrings are a group of three muscles located at the back of the thigh. These include the semimembranosus, semitendinosus, and biceps femoris. They are responsible for bending the knee and extending the hip.

The other muscles mentioned in the question are not located at the back of the leg. The deltoid, trapezius, and extensor carpi radialis are upper body muscles. The quadriceps, tibialis anterior, and fibularis longus are located at the front of the leg. The frontalis, masseter, and buccinator are facial muscles.
