front of the thigh and a portion of the lateral surface takes quadriceps muscle, head which starts separately.And they are united in the knee tendon attaches to the tuberosity, located on the tibia and the patella covering.
quadriceps - a set of four heads, and the longest one is the rectus abdominis, which completely covers the front surface of the thigh.It begins in nadvertluzhnoy groove, moving from the front axle lower down, moving in a narrow tendon, which is part of the tendon.
Wide medial muscle located in the lower half of the hip and takes it forward medial surface.It originates from a rough line, and from its medial lip goes down, transformed into a broad tendon partially intertwined with the rectus muscle and is attached to the edge of the patella, forming its supporting ligament.
Another head occupies the front lateral surface and is called the vastus lateralis muscle of the thigh.It's a little closed and rectus muscles that strain the fascia lata.It starts from the general line of hip, in an area where the greater trochanter, intertrochanteric line and lateral lip.Lower down it goes into wide tendon is part of the tendon and is involved in the formation of the supporting lateral patellar tendon.
fourth head - a broad intermediate muscle, which is located between the medial and lateral muscles.It is under the rectus femoris is the weakest of the head.Taking its origin in the plane of the front of the femur, an intermediate half the length of a muscle goes into a broad tendon which, in turn, is attached to the tendon and the rectus muscle goes into a common tendon.
quadriceps as triceps thigh, solve the basic problem, which is the extension legs at the knee, and rectus also helps to flex the hip.She is very strong and large, because it helps the knee joint to withstand weight.Quadriceps femoris has two functions, it is a dynamic, consisting in straightening maple in motion and static, which prevents podgibaniem knees when standing still.
All muscles requires a certain load.To quadriceps successfully fulfilled its main function, it is necessary to constantly maintain in good shape.For this good exercises such as the classic sit-ups, squats with a barbell or dumbbells, leg presses, lunges with dumbbells.
Bruising of muscles can occur when hitting the front or side.It is accompanied by pain and swelling, range of motion in the knee and hip joint is reduced.The intensity of these symptoms depends on the force of impact.A little later, you may receive a bruise or hematoma eventually increase in size and come down.There are times when it goes to the lower leg or foot.The diagnosis of quadriceps contusion Becoming a doctor as to exclude other possible damage.To check for a fracture, radiography, and with ultrasound measures the size of the hematoma and muscle defect.
In some cases, these complications can occur in the muscle as subfascial hypertensive syndrome, ie the infringement and myositis ossificans, characterized by the deposition of calcium salts.Quadriceps injury after treated painkillers, retained its strength and mobility of the knee, performed the prevention of myositis using NSAIDs.
