Muscles of the back are an important integral part of the active motor function of the spine. Without them, no movement would be possible. At the same time, they are used by the human body not only for movements, but also play an important static supporting role, supporting and fixing each other as separate elements of the spine - the vertebrae, and the spine in general, setting and supporting its natural curves. Thus, the back muscles never rest in the active wakeful person, who is in an upright position. One can imagine how tedious and difficult their work is.
My name is Vlad Litvinenko and now we will consider 10 facts regarding the functions, anatomy and features, as well as back muscles training for men and women.
1. The main functions of the back muscles
First, let's look at the basic functions of the back muscles, which include:
1. Constant fixation of the vertebrae with each other to provide a fixed support. Without this, no our turns and inclinations, bending and unbending would be possible
2. Maintaining the back and neck vertically
3. Raising arms and shoulders, as well as moving them
4. Providing the motor activity of all vertebral departments
5. Maintaining natural curvature of the back (cervical and lumbar lordosis and thoracic kyphosis) within the required limits
6. as well as amortization of the spine with active movements
2. Consider the back muscles from the anatomical angle
One of the most important, supporting the spine vertically, is the rectifying spine muscle:
It is a powerful muscle located on the surface of the deep, passing along the entire vertebral column and filling all the indentations from the spinous processes to the rib surfaces.
Its functions are:
• support of the vertical position of the trunk
• extension of the spine and its slopes
• turns of the head
• also partially participates in breathing
3. Trapezius muscle:
Two muscle triangles on both sides of the spine, with a base near the vertebral axis and apex near the scapula acromion, form a trapezium shape. Their tendons are short, only on the border of the cervical and thoracic region they are somewhat longer, form a platform in the form of a rhombus.
.
Their functions are:
• Raising hands up
• Movement of the blades - raising, lowering, approaching the blades
• Head inclinations in different directions
4. The widest back muscles
The widest back muscle covers a wide area: from the humerus to the ilium, crossing the oblique back, occupying the entire lower part and forming a lower lumbar triangle.
It is covered at the top in a small area near the spine trapezoid.
The widest back muscle performs the following functions:
1. Provides the movement of the shoulder with the pulling of the arm back to the vertebral axis with pronation (rotation inward)
2. It makes it possible to pull the trunk to the hand while fixing the trunk, and with its powerful development, it becomes possible to brachyce, that is, movement with the help of hands, which monkeys are always willing to use.
