What is rectus femoris?
rectus femoris is one of the four muscles that form a group of quadrilateral muscle. Its primary function is to bend the hip and extend the knee, making it important muscles for a number of activities that require the movement of the lower body. The muscle is placed in the middle of the thigh and leads from the bottom of the spine down to the knee chamber. Only the Sartorius muscles are also included in the group of the quadrilateral muscle and is connected to the hip and knees.
rectus femoris has two origin. The first is the front origin and occurs at the bottom of the spine. There is also a rear origin in the acetabul. Both of them begin with tendons and meet before they run to the thigh, where muscle fibers begin. The insertion of the muscle is through the tendon known as a quadriceps tendon that connects with the patella.
The knee extension is one of the main tasks of Rectus Femoris. However, this muscle becomes weaker in relation to the hip when the knee is prolonged because it shortens, which means it cannot work too. For this reason when rectus femoris is shortenedENA, other muscles are more involved in the hip flexion.
In a similar way, the muscle is also weaker in the elongation of the knee when the hip flexion. Again, this is because the muscle is placed in a short state and cannot provide the same level of strength. In this situation, the elongation of the knee is achieved by other muscles in the groups of four -headed people.
Three other main muscles in the group of muscle muscle quadrices are huge lateralis, huge intermediate and huge medialis. All these muscles help maintain the patella stable while extending the knee. For this reason, they are all necessary for basic activities such as walking or running. Rectus femoris is the most important of the muscles and is named the appropriate way in which it reaches the front part of the thigh.
If this muscle tears, it becomes serious and painful injuries. Ruptura tendon rectus femoris often occurs repeated onTymeous use of muscle during events such as kicking or sprinting. Symptoms include sharp pain in the hip or weakness along with bruises and sometimes swelling. The area will also be usually painful.
