The muscles of the knee include the quadriceps, hamstrings, and the muscles of the calf. These muscles work in groups to flex, extend and stabilize the knee joint. These motions of the knee allow the body to perform such important movements as walking, running, kicking, and jumping. Extendi...
In our evaluation, the participants were motivated to bring the knee to extension, until myoclonus was observed between the flexor and the extensor muscles. At the end of knee extension, the participant was instructed to move the knee to some degree of flexion to stop the myoclonus. The Cut...
Treatment of these gait abnormalities is challenging because the factors that extend the knee during normal walking, over a range of speeds, are not well understood. This study analyzed a series of three-dimensional, muscle-driven dynamic simulations to determine whether the relative contributions of...
Located on the back of your thighs, the hamstrings are a group of three muscles that are responsible for knee flexion and hip extension. The three hamstring muscles are the semimembranosus, semitendinosus, and biceps femoris. Abductors The abductor muscles lift your legs out and away from the ...
Meanwhile, the medial thigh muscles are located between the anterior and posterior muscles. Mostly, they're conformed by the adductors — although they also contain the gracilis and obturator muscles, which help rotate, extend, and adduct the knee. ...
The quadriceps are a group of muscles in the anterior compartment that are also known as "quads." The muscles are known as vastus lateralis, vastus intermedius, vastus medialis, and rectus femoris muscles. The function of these muscles is to extend the knee and stabilize the knee bone or pa...
They maintain body or limb position, such as holding the arm out or standing erect They control rapid movement, as in shadow boxing without landing a punch or the ability to check the motion of a limb For example, to extend the knee, a group of four muscles called the quadriceps femoris...
This large muscle group consists of three muscles that run from your hip down to your knee. These muscles help you walk, climb stairs and squat down. If you have hip or knee pain, you might want to give a little extra attention to your hamstrings, as they help bend the knee and ...
The quadriceps femoris muscle group straightens the leg at the knee. The hamstrings are antagonists to the quadriceps femoris muscle group, which are used to flex the leg at the knee. The muscles located in the leg that move the ankle and foot are divided into anterior, posterior, and ...
Controls the movement of the patella (kneecap) 2. Hamstrings Location:The hamstrings are found on the back of the thigh from the hip to the knee Action:Their main action is to bend the knee, but they also help to extend the hip
