What muscle is located on the lateral side of the thigh?
The vastus lateralis muscle is located on the lateral side of the thigh. This muscle is the largest of the quadriceps which includes: rectus femoris, vastus intermedius, and vastus medialis. Together, the quadriceps act on the knee and hip to promote movement as well as strength and stability.
Which muscle group is used to stand up from sitting?
In everyday life, the quadriceps muscle group as a whole allows a person to stand up from sitting, walk up or down stairs along with basic walking and running. These muscles are not active while standing with knees fully extending, but become active during the heel-strike and toe-off phases of gait.
Where does the vastus lateralis muscle come from?
The vastus lateralis muscle arises from several areas of the femur, including the upper part of the intertrochanteric line; the lower, anterior borders of the greater trochanter, to the outer border of the gluteal tuberosity, and the upper half of the outer border of the linea aspera.
What is the largest muscle in the thigh?
Vastus lateralis muscle. The vastus lateralis ( / ˈvæstəs ˌlætəˈreɪlɪs, ˈræ -/ ), also called the ''vastus externus'' is the largest and most powerful part of the quadriceps femoris, a muscle in the thigh.
Where does the tibia connect to the quadriceps?
It ultimately joins with the other muscles that make up the quadriceps in the quadriceps tendon, which travels over the knee to connect to the tibia.
What muscle extends the knee?
Collectively, the quadriceps muscle is the largest in the human body and its purpose is to extend the knee.
What are the muscles of the legs?
Taken together, the muscles of the legs allow strength and stability. They provide power for and absorb the impact of daily activities such as walking, running, and jumping. Common injuries to the vastus lateralis muscle include strains and contusions.
Which muscle is the largest in the human body?
Collectively, the quadriceps muscle is the largest in the human body and its purpose is to extend the knee. The specific task of the vastus lateralis muscle is to extend the lower leg and allow the body to rise up from a squatting position. On the upper end, the muscle attaches to the femur; on the lower end it attaches to the patella, or kneecap.
What is a strain in a muscle?
A strain is actually a tear in the muscle and can result from an improper warm up before physical activity. A contusion is when the muscle is crushed against the bone, and is usually the result of an impact such as a bruising injury. Last medically reviewed on January 20, 2018.
What is the Vastus lateralis?
Vastus lateralis. Superior portion of intertrochanteric line, anterior and inferior borders of greater trochanter, superior portion of lateral lip of linea aspera, and lateral portion of gluteal tuberosity of femur. Vastus lateralis is supplied by the muscular branches of the femoral nerve.
Which nerve supplies the Vastus lateralis?
Vastus lateralis is supplied by the muscular branches of the femoral nerve. Primary nerves of the anterior thigh. obturator nerve. femoral nerve. origin. L2-4 of lumbar plexus. motor. extensors of the knee. recuts femoris.
Importance of Muscle
Vastus lateralis muscle with other quadriceps muscle group as a whole work together helps you to stand up from sitting, stair climbing, running, squating and walking activity.
Vastus lateralis muscle exercise
Vastus lateralis muscle exercise are mainly 2 type – Stretching exercise and strengthening exercise.
What muscle is used to extend the knee?
The vastus lateralis is one of four muscles that make up the quadriceps. These muscles work together to extend the knee. The vastus lateralis is located above the knee joint, toward the outer edge of the leg. It lies beneath the iliotibial tract, which is a band of fascia that runs vertically along the outer thigh. The vastus lateralis is susceptible to muscle fiber tearing -- which is called a muscle strain -- through knee extension in sports and everyday activities.
How to treat a largeus lateralis strain?
Immediately apply crushed ice to the outer thigh area, gently compress the ice with a tensor bandage and elevate the thigh above the heart to reduce swelling. Prior to any other treatment, consult a physician for optimal recovery.
