gluteal muscle goup
This muscle is also used to flex the thigh. The rectus femoris is the only muscle that can flex the hip. Injury to the rectus femoris muscle may result from overuse, as seen with kicking- or sprinting-related injuries. Inflammation of the muscle causes pain in the groin during physical exercises that use this muscle.
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.
Extension. Extension increases an angle, as in straightening a joint. During extension, the knee or elbow are straightened.
The triceps brachii muscle does not flex the elbow; it is responsible for extending the elbow joint when it contracts.
The flex
To extend the leg straight at the knee you use the quadriceps. To bend the knee, you need the hamstring.Hamstring muscle groups.
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.
Biceps Femoris, Semimembranosus, and Semitendinosus
Much of the semimembranosus lies deep to the semitendinosus.
The Femoral nerve. (The motor branches innervate anterior thigh muscles - quadriceps, which flex the thigh and extend the knee.)
Quadriceps contracts to extend the knee joint. Rectus femoris, the part of quadriceps flex the hip joint on the thigh.
Semimembranosus, semitendinosus, and biceps femoris ... The hamstrings
The psoas is one of the flexors of the hip.
The muscle of the thigh are classified into three groups, anterior group, posterior group, and interior or adductors group. There are four muscle on the anterior group - quadriceps femoris- and their function is to extend the knee or extend the thigh depend on what part of the muscle don't move. Those muscle are the rectus femorarlis, vastu intermedius, vastu medialis, and vastus lateralis. The muscle that flex the knee are located on the back of the thigh and form the posterior group. They are the biceps femoris, semitendinousus, and the semimembranosus, better known as Hamstring.
The location of the quadriceps is in the upper thigh area kind of by the hip abductors and the anatomical position of the quadriceps is flex-ion. It is located in the front of he upper thigh above the knee.The quadriceps are anterior to the hamstrings.Anterior: In front of
