Group, the structure and function of the muscles of the back and neck

Б.в

A Properly developed back muscles allow good posture and a confident gait of any person. Moreover, straightened his shoulders and straight posture allow the body to consume more oxygen, therefore at the end of the day fatigue will be significantly lower than those who allow the back to slouch. We offer you a closer look at the structure and location of the group of muscles of the back, and even then, what functions endowed with the main ones.

Anatomy back muscles human

muscle Group of back

It is Obvious that the muscles of the back and neck occupy a large area on the human body, starting from the field at the top of the neck and finishing with lumbar Department of the back. The main support for the spinal muscles is the spine, and one of the main functions of the muscular system is to hold your spine in a straight position, in which the lungs receives maximum oxygen.

Typically, major muscle groups can be divided into deep muscles and superficial muscles of the lower back.

deep back muscles "are responsible" for the stability of the spinal column, they are also known under the name of transversospinales muscles. In this group of muscles there are three layers, of which the deepest are considered to be muscles, rotator cuff, then go multifidus and semispinalis muscles closest to the surface in this group. The main function of this group is to ensure precise movements of each of the vertebrae, thus ensuring the stability of the entire back.

Another group of muscles that attaches exclusively to the spine – extensor muscles of the spine. In this group there are three categories of muscles, the names of which are as follows: iliac rib, longissimus and spinalis. As the name implies, these muscles help the spine to make movements forward and backwards, i.e. The back of them has the ability to bend and straighten.

In addition, in the upper back are the trapezius, rhomboids and levator scapulae muscles.
The trapezius muscle, often referred to simply as "trapeze", are located in the back of the neck and look like a triangle, the base facing the vertebral column, and the top is toward the scapula. These two triangles, located on both sides of the spine, and visually they form a geometrical figure on which the name of this muscle group.

The Function of this muscle group is to control the movement of the blades, they are partially involved in the movement of the neck, support head, etc.

This large group of back muscles – superficial muscles. It's quite a large group that includes many different muscles situated in the lower back. The most famous of them is called latissimus. This muscle is the largest in this region and it is located in the area from the humerus to the iliac area, thus crossing the plane of the back. A portion of it is covered by the trapezius muscle. Widest makes possible the movement of the shoulder whereby the hand is drawn back to the spine. In addition, it allows you to tighten the torso to the hand that with the proper development of this muscle enables the movement of the body using the arms. In this way the movement often use primates, but people are still able to do that.

Latissimus dorsi

For side bend meets the square muscle of the loin. with in addition, because of the peculiarities of its structure, it helps to extend the lumbar spine.

The Location of the rhomboid muscles belong to the upper region of the back, is this directly under the trapezius muscle attached to the medial scapular edge. Its function is especially noticeable when a man takes her back down or Vice versa, and compresses them. The rest of the rhomboid muscle fixes the medial border of the scapula, pressing it to the sternum.

You Should specifically say about another muscle, which is called large round, or as it is called – small wings. This name is due to its location and flat elongated shape. This muscle is located under the widest and works in close conjunction with it. However, the big round muscle is responsible for several functions: pulling the arms down and backward, by the rotation of the arm in a direction inward and bringing the hands to the body.

Weakest link

we can't avoid mentioning the weak point of the muscle corset back, which, if you do not pay enough attention to him, under the influence of severe stress can lead to lumbar hernia. This so-called the lumbar triangle, formed with the participation of the obliques. Although not relevant to the back muscles, they play an important role in the formation and strengthening of the muscle corset that supports the spine.

Lumbar triangle is limited behind by the broadest muscle of a back, front external oblique muscle of the abdomen, from below the iliac crest.

Quite often, due to asymmetrical muscle development disorders occur in the posture, which subsequently leads to diseases of the spine or to disease of internal organs. To achieve symmetry in the structure of muscle groups it is possible with the help of various physical exercises, exercise or fitness equipment.

Methods of training

You Can strengthen your back muscles at home without visiting the gym. But before you start doing exercises before you workout a bit to stretch the spine in order to avoid such troubles, pinched nerves, etc.
