The back sirve, báphysically to support the body and allow its movement, además of to help keep the center of gravity stable, both at rest and when in motion. Además of these functions, spaghettién is in charge of protecting the médula spinar when found wrapped in bone.
To be able to support the weight of the body, the back has to be sólida; and for this reason it is made up of very resistant bones and múpowerful dogs.
To allow movement, the spine must be flexible, for which it is not composed of a single bone ríguide, but it is made up of a total of 33 véseparate vertebrae. These are arranged one above the other and isán supported at the same time by a system of múmuscles and ligaments.
To help keep the center of gravity stable, the contractionón of back muscles actúa in the form of a counterweight that compensates for the movements of the rest of the body. In order to be able to actí, the muscles have to be powerful.
in addition, It must be taken into account that for the protectionón of the méspinal game, the Vévertebrae have a special shape, since it has a hole in its center through which the médrama.

Spinal column
The spine of the human being is made up of a total of 33 vévertebrae, of which are 7 cervical, 12 dorsal, and 5 lumbar, which are separated from each other by a total of 23 intervertebral discs. The five sacra are made, just like the 4 coxígeas, forming the sacrum and coccyx bones.
If you look at them from the front, the Vévertebrae are perfectly aligned with each other and form a vertical. Nevertheless, Profile, shape curves. the top, in the cervical area, which have the function of protecting the vital organs, in the lower back, his Códig backás and receive the name of lordosis-cervical y lumbar, respectively. The mean curve is códigs forward and is called thoracic kyphosis.
It is availableón makes the column very resistant to the load that is applied in the opposite direction.ón vertical, since its curvatures give it flexibility. In case the load is very important, curvatures may increase temporarily, in charge of cushioning the pressureón who suffer their own vévertebrae.
Whaté is lower back pain
Once the information is knownóprevious n about the bones of the back at the anat levelómonkey, It's time to analyze the lumbar pain, and it is that one of the pathologiesías más frequent takes place on the back of the body.
The pain of the regionón lumbar or low back pain is a pain that is located in the lower part of the back. The origin of this has to do with the structure músculo-esqueléspinal cord.
The pain, in the back, It usually occurs in the lower back and is caused by a neurological mechanism.ólogical that implies that the nerves that transmit pain are activated and the triggering of muscular contracture and inflammationón.
On other occasions, the pain is generated due to compressionón of a raíz nervous, as it happens in the case that an intervertebral disc suffers a lot of wear and does not cushion enough, it is possible that some ra is compressedíz due to concussionónot in this area.
The process that is followed in this case involves starting to activate specific receptors related to pain, known as nociceptors. Its activationóIt causes pain and causes an inflammation mechanism to take place.ón and a muscle contracture.
The inflammationón and contracture keep pain receptors active and that makes it a círculo, with a pain that causes inflammationón and this inflammationódoes not cause pain. In this situationón, the pain is maintained despite the fact that the cause that caused it may disappearó triggering it at the beginning.
This mechanism may be caused by a lesionón structural but alsoén can occur without it occurring, being in fact the case más común, when this mechanism is triggered without the existence of a lesionóstructural no. This happens, for instance, when an incorrect posture is maintained that gives rise to muscular overload; and in turn that leads to a contracture.
Cóhow to know if you have a back problem
If a subject has dysmetríin the lower limbs, muscle imbalances in lower extremities or múscules on the back, Back pain, hip or leg injuryónot or without her, the hypotoníto in the core, occurs for example by maintaining an incorrect posture
occurs for example by maintaining an incorrect posture, quizás in childhood has not been detected, but that very probably with the passing of the yearsños, but that most likely over the years, but that most likely over the years.
Currently, it is known that there is a relationshipósignificant n between back pain and lack of prásports practice and with the time spent in front of the computer or televisionón
Thus, but that most likely over the years, móvil o televisión, but that most likely over the years.
The main cause of back problems or muscular alterations and decompensations is the adoption ofóNo inappropriate postures in daily life .
The alterations más frequent are the following:
- Scoliosis. deviationón lateral of the vertebral column, being the causes in meás of the 85% of unknown cases.
- hyperkyphosis. It consists of the increase of the anterior concavity of the dorsal column, which is usually due to prolongedóNo inappropriate postures or lack of strengthening of the paravertebral musculature.
- the increase in curvature is perceived. It is the increase in the posterior concavity of the vertebral column., región lumbar. In many cases, the cause is unknown., but the shortening of the hamstring musculature can facilitate the adoption ofón of incorrect postures, and these can cause it to dé an alterationón in this concavity.
For this reason it is very important to maintain a work and strengthening of the back.
