The muscle group is called the Quadriceps
gracilis , adductor longus , adductor brevis and upper part of adductor magnus
The primary muscle responsible for extending the thigh is the quadriceps femoris, specifically the rectus femoris. To flex the knee, the primary muscles involved are the hamstrings, particularly the biceps femoris, semitendinosus, and semimembranosus. These muscle actions are important for movements like running and kicking.
The hamstring group consists of three muscles: biceps femoris, semitendinosus, and semimembranosus. These muscles are located at the back of the thigh and function to flex the knee and extend the hip.
The quadriceps femoris is a group of four muscles located on the front of the thigh that work together to extend the knee and flex the hip. These muscles are important for activities like walking, running, and jumping.
Semimembranosus, semitendinosus, and biceps femoris ... The hamstrings
To extend the leg straight at the knee you use the quadriceps. To bend the knee, you need the hamstring.Hamstring muscle groups.
not sure if this is anything of what you are looking for, but the muscles to the front of the thigh are the quadriceps's, the back of the thigh are the... um.. hamstrings. I couldn't find the muscles on the side of the thigh.. :D
The primary muscles responsible for flexing the leg at the knee joint are the hamstrings (biceps femoris, semitendinosus, semimembranosus) and the gracilis. These muscles work together to bend the knee and bring the lower leg towards the thigh.
The Femoral nerve. (The motor branches innervate anterior thigh muscles - quadriceps, which flex the thigh and extend the knee.)
to make it tight
Paralysis of the quadriceps femoris muscle would make an individual unable to flex the thigh. This muscle is responsible for extending the knee and flexing the thigh at the hip joint.
The three thigh muscles that help you you keep astride when riding a horse are the thigh adductor muscles; magnus, longus, and brevis.
