Straining the spine muscle: functions and strengthening

The straightening spine muscle is the most powerful and longest on the back. It fills the whole space on the sides from the spinous processes to the ribs. And in length it passes all along the spine. It starts from the sacrum and extends to the very base of the skull. She takes part in turning the head and lowering the ribs. But the main function of the muscle that straightens the spine is to hold the body in a straight position. In the process of evolution due to the uprightness, it became the strongest among the muscles of the trunk.

Anatomy of the muscular corset of the spine

The body in the right position is held by many muscles of the back, abdominal and chest. They make up a muscular corset that protects the spine and internal organs. Some of these muscles are more significant, while others perform auxiliary functions. The health of a person depends on the condition of the spinal column, so strong back muscles are very important, since they keep the vertebrae in place. Their significance is great, since they participate in almost all movements.

Muscles, straightening the spine, refer to muscles that lie deep. They perform work to protect and move the spine. They also include the back muscle of the back, which extends from the thoracic to the cervical vertebrae and participates in the turns and inclinations of the head. A number of small muscle bundles form a transverse-spinous muscle of the back.

Above these are superficial ones: trapezoidal, latitudinal, rhomboid, upper and lower jagged muscles.

Structure

Deep back muscles, which are united under the same name "straightening the spine muscle," are located along the entire vertebral column. They are a few small and large bundles of muscle tissue that attach to the bones of the pelvis, the ribs and transverse processes of the vertebrae. It is divided into three parts at the level of the upper lumbar vertebrae.

In the lumbar region, the largest muscle bundles depart from the bones of the pelvis and the sacrum. In this place the extensor function is performed by the muscle, which straightens the spine. Attachment of its lumbar part in the upper part is carried out to the ribs and transverse processes of the vertebrae. Therefore, this part is called the iliac-rib muscle.

The longest muscle of the back joins the transverse processes of the vertebrae. It is often treated as a single entity with the iliac-rib, but it is located medially.

The spinous muscle of the back is attached to the spinous processes of the thoracic and cervical vertebrae.

Functions

It is called the extensor or rectifier of the spine. The degree of development of this muscle depends on the person's posture, gait, and health of the spine. It participates in the torso, corners, and balance. It strains when coughing, moving the diaphragm and during defecation. But in addition to this, the straightening muscle of the spine performs a static function. It supports the body in a straight position and ensures the stability of the spine in all movements. It is these muscles that protect the spine from any damage, keep it in the right position.

Reduction of individual parts of this muscle allows you to tilt back the head, unbend various parts of the spine, lower the ribs. When it is unilaterally reduced, the slopes of the body are drawn to the sides.

The value of the muscle that straightens the spine

It is from her work that the posture and health of the spine depends. If this muscle is weak or affected by the disease, any movement of the person causes pain. It is even problematic to keep the body in a vertical position. If the spine is bent, the volume of the chest and abdominal cavity changes, which leads to various diseases of the internal organs.

The problems that arise in its functioning

The straightening muscle of the spine is often the object of patient complaints. Throughout life, it can withstand a huge load. After all, it should maintain the stability of the spine in any movement. And if there are any problems in its functioning, the spine loses mobility, is affected by various diseases. Usually this happens with increased load, frequent lifting of weights, supercooling. May develop myositis, myalgia, lumbago. Pain also occurs with osteochondrosis, displacement of the vertebrae, intervertebral hernia.

If, due to overwork, the muscle that straightens the spine weakens, stability of the vertebrae is impaired. There may be pain due to her spasm or because of the infringement of the nerve roots. This often occurs in the lumbar spine. Therefore, people who spend a long time in one position or under a loin high load, it is necessary to perform special exercises.

Muscles that straighten the spine: how to train and relax

A feature of these muscles is their slow recovery. Therefore, it is often not recommended to strain them. Training with strength exercises is best done no more than 2 times a week. In the rest of the time, exercises should include exercises to relax and stretch these muscles. This will help relieve their spasm:

• The simplest exercise for relaxation of the muscles of the back is hanging on a horizontal bar. In this position it is recommended to stay for several minutes 2-3 times a day.
• To sit on a chair, legs to spread widely, hands to lower. Slowly exhaling, alternately bend the spine in the cervical, thoracic and lumbar region, drawing in the belly. On inhalation straighten, straightening the back in the reverse order.
• Lie on your back, clasp your knees with bent legs. On inhalation, put your feet on your hands, as if trying to unbend them, exhale - to bring your knees together.

How to strengthen the muscles

The straightening muscle of the spine performs the basic task of keeping the body in a straight position. Therefore, it is very important to strengthen the muscular corset of the spine. Many diseases of the musculoskeletal system appear due to the fact that the muscle that straightens the spine is very weak. Exercises will help to strengthen it:

• You can start with the usual torso of the trunk from the standing position. Then to increase the load add weighting.
• Lie on your stomach on the couch, feet on the weight. On inhaling, raise your legs, tighten your buttocks, stay for 5-8 seconds, on exhalation - lower them below the level of the couch.
• A similar exercise is performed when the upper part of the body is on weight. Hands behind the head or on the belt, lift the body, staying in the upper position for 5-8 seconds.
• Lying on my stomach, hands behind my head. Raise the upper part of the body, flexing consistently cervical, thoracic and lumbar spine. Hold in this position for 5-8 seconds.
• The starting position is the same. Hands stretch forward and inhale at the same time to raise the upper part of the body and legs.

To the back muscles perform their tasks to protect the spine and keep it in the right position, they need to be strengthened. For this, regular exercise, sleep on the orthopedic mattress and frequent breaks with sedentary work are important.
