Muscle Straight (Rectus)

Muscle Straight (Rectus): anatomy and functions

Muscles play a key role in the functioning of the human body, providing motor activity and maintaining posture. One of the most famous and important muscles is the Rectus muscle, which is located in different parts of the body and performs different functions.

The rectus abdominis muscle (Rectus abdominis) is a long, ribbon-shaped, flat muscle that runs on both sides of the anterior wall of the abdomen. This muscle consists of two parallel bundles that are separated by the line alba (linea alba). With bilateral contraction, the rectus muscles tilt the torso forward and reduce the size of the abdominal cavity; acting separately, they tilt the body in their direction.

The rectus femoris muscle is part of the quadriceps muscle, which is located in the front of the thigh. This muscle starts from the femur and goes down, ending at the kneecap. It plays an important role in hip movement, especially in leg lifting and knee flexion.

In addition, the rectus muscle is found in other parts of the body. For example, the four rectus muscles of the orbit carry out its movements. They start from the bones of the orbit and end on the sclera of the eye.

Due to its location, the Rectus muscle can become a source of pain and discomfort if its use is associated with overuse or injury. However, regular exercises of the rectus abdominis and rectus femoris muscles can strengthen them, improve posture and reduce the risk of injury.

In conclusion, the Rectus muscle is an important muscle in the human body that performs various functions in different parts of the body. Regular exercise can improve fitness and reduce the risk of muscle overuse injuries.

Muscle Straight (Rectus): Anatomy and Functions

Muscles play an important role in the movement of the human body. One of the most well-known types of muscles is the rectus muscles, which have a smooth, straight shape and are located along the axis of the body. One example of a rectus muscle is the Rectus muscle, which is found in various parts of the human body.

The rectus muscles of the eyeball, or Rectus muscles of the orbit, consist of four muscles, each of which is responsible for a specific direction of eye movement. Muscles The straight orbits start from the orbital bones and end on the sclera of the eye. They control the movement of the eye, allowing it to rise, fall, rotate and tilt.

The rectus abdominis muscle (Rectus abdominis) is a long, ribbon-shaped, flat muscle that runs on both sides of the anterior wall of the abdomen. It is one of the main abdominal muscles and is involved in many body movements. With bilateral contraction, the rectus abdominis muscles tilt the torso forward and reduce the size of the abdominal cavity; acting separately, they tilt the body in their direction.

The rectus femoris muscle is part of the quadriceps femoris muscle. This muscle starts from the femur and ends at the tibia. The rectus femoris muscle controls hip flexion and is involved in lifting the leg.

In general, the Rectus muscle plays an important role in the movement of the human body and controls different directions of movement, depending on its location in the body. It is a key muscle in many physical and muscle strengthening exercises. However, before starting any exercise, it is necessary to consult a specialist to avoid injury and improper stress on the muscles.

Muscles. Despite the fact that they are part of the musculoskeletal system, in our minds they are usually associated not with movements, but with body qualities. For example, someone with six-pack abs clearly means that the person has strong abs and has powerful, developed abdominal muscles - the rectus abdominis, external oblique and internal oblique; The expression “loose belly” is usually attached to something weak and flabby, as if from poor nutrition or poor sleep. Elastic, pumped up legs are perceived in the same way - some people take pictures of them and boast about it, while others find them unpleasant and even repulsive.
