Nerve root
Latin: radix nervi) is the initial segment of a nerve leaving the central nervous system . Nerve roots can be classified as:
Cranial nerve rootsCranial nerves originate directly from the brain's surface: two from the ventral) roots, but can emerge from one fusion root instead;[3] of the eleven cranial nerves, four express this concept of fusion. The remaining eight nerve roots only express one of the two types of connections. Five of these are exclusive motor roots, and the remaining three are all sensory.[4]
Spinal nerve rootsSpinal nerve roots are much more uniform than vertebra along the spinal column.
The specific vertebrae classify spinal nerve roots they originate from. These are separated into three sections: cervical, thoracic, lumbar, and sacral. The cervical is separated into eight vertebrae named C1-C8. The thoracic segment consists of T1-T12; the lumbar is L1-L5; and sacral S1-S5.[5] Pain and pathologiesDamage to nerve roots can cause radiculitis and sciatica, are among the most common symptoms caused by damage to the nerve root. Radiculopathy is commonly called the "root". In addition to pain, nerve damage may lead to impaired muscle control. Typically, mechanical dysfunction is caused by pressure on the nerve root or shock, affecting both the lower limbs and arms' roots.
The first sign of disease (sometimes preceding the occurrence of the radicular syndrome by up to a few years) is a sensation of poor posture or ergonomics during work or sleep, or sudden head movement. Team roots are localized mostly within the three lower cervical roots, namely C5, C6, and C7.
Symptoms
C5 radiculopathy
C6 radiculopathy
C7 radiculopathy
TreatmentTreatment should be initiated as early as possible, before any muscle tone increases, which further intensifies the pain. Traction is recommended to decompress compressed roots. Radiculopathy can be caused by herniated nucleus pulposus. Surgery is the last resort when conservative therapy is unsuccessful. Lower limb radiculopathiesThe cause is a lumbago , which usually occurs with periods of remission. The time to develop a full radicular syndrome may take several months or several years. Pain generally increases gradually, but it can also be sudden. Cold causes muscle contraction, which leads to increased previously hidden symptoms.
Symptoms
L4 radiculopathy
L5 radiculopathy
S1 radiculopathy
TreatmentTreatment can vary based on the nature and severity of the disease. A compressed nerve root can cause radicular pain with or without radiculopathy. Most of the time, symptoms from a compressed nerve will start to feel better within 6 to 12 weeks of nonsurgical treatment. To unlock the nerve root in the acute phase, it is recommended to apply traction and isometric muscle relaxation, and should be the first procedure to be performed in cases of severe pain. In cases where manipulation is undesirable or impossible to carry out, the infiltration may be root.[clarification needed] Anti-inflammatory medications may be used to alleviate symptoms. In the acute setting, the main goal is to restore proper mobility by reducing pain. Surgery is used when other methods do not produce results, except when paralysis is observed; in those cases, surgery should be performed as soon as possible to avoid irreversible paralysis of muscles.
