Dermatomas are specific areas of the body that are inert by a nerve in the spine consisting of 33 vertebrae and 31 pairs of nerves distributed throughout the body in an organized manner.
Each nerve that sells the spine is responsible for giving sensitivity and strength to a certain area of the body, so when there is a compression of the nerve, it is hooked in the area of the body, so it is possible to identify the part of the spinal cord that has been affected by compression, trauma in the herniated disk, when a person expresses a feeling of stress , weakness or inability to move the arm to the side of the cake, for example.
- That’s why there are 31 skin lesions that are divided into sections.
- As if they were changing in the following image:.
To identify the most sensitive eruptions, you have to look at a person standing at all four ends, because this way the “cuts” are more easily identified. These are the main sensitive dermatologists:
The skin map is used by doctors and physical therapists to identify the presence of changes or compression in the marrow because, if changes in sensitivity occur in a certain area of the body, it is easier to identify the area of the spine that is compromised, it is caused. trauma or a herniated disk like what.
In addition, dermatomas can also be used in alternative therapies, such as reflexology in acupuncture, to directly stimulate areas of the bone marrow or other organs that are inert by the corresponding pair of nerves, so the acupuncturist will be able to apply water to the desolate area of the spine to relieve pain and ailments that occur in other areas of the body.
Dermatomas involve the sensitive part of the skin, but myotomas are responsible for the motor inervation of the muscles in this area. In the following table, some examples are modified:
Flexion of the forehead and extension of the wrist
Foot Eversion Muscle Extension Stem Flexion
Stretch out your forearm and flex your hand
Extend the thumb and ulnar movement of this finger
In this way, when the person expresses a feeling of numbness on the side of the cake, chances are there will be a change in the spine, especially in the vertebral area from L5 to S1, as is the area inert by the dermatoma. On the other hand, if there is weakness and difficulty flexing the arm, the affected area is cervical C6 and C7, although this is my fibroid.
