What is a lower lesion of a motor neuron?

generally concerns the "lesion" of the medical term for any kind of damage or damage in the body. It can also refer to any physical changes that can occur due to a disease that creates problems in the way the body or part of the body works. Lower lesions of motor neurons indicate damage affecting neurons associated with muscles. Motor neurons translate these roads directly or indirectly affecting muscles. Neurons are generally divided into two categories: upper motor neurons and lower motor neurons. Upper motor neurons send signals to a specific area, while lower motor neurons innervate or pass muscles. Lower lesion of motor neuron affects the body's ability to move by interrupting signals from the brain and spinal cord, which are sent to these muscles.

Although the two types of nerves include muscles and affects their ability to move properly, the difference between the upper motor neuron and the lower lesion of the motor neurontaci. Although the upper motor neuron also affects the muscles, it causes different symptoms because it disrupts the nerve pathways above the front corner of the spinal cord, the section before the gray matter in the spinal cord. On the other hand, lower motor neurons affect the nerves from the front corner directly into the muscles.

Depending on the exact location of the injury and on which the muscles are disrupted, the common symptoms of a lesion with a lower motor neuron include things such as fibrous fiber or fibrillation, involuntary muscle fibers and vibration of individual muscle fibers. Another result could be a flabby paralysis, resulting in the inability to move and cause to and loss or loss of muscle tone and muscle reflexes. Long -term weakness can cause muscle degeneration, a condition known as atrophy or waste of muscle.

The causes of lower lesion of motor neurons can range from a certain type of damage to nerves to health conditions aso is amyotrophic lateral sclerosis, also known as Lou Gehrig's disease or ALS, causing progressive loss of engine control. In general, if the reduction in motor function is caused by injury, muscle control may be re -controlled, as the nerve pathways heal, a process that can last anywhere from a few months to several years. However, if dysfunction is caused by the disease process, treatment can usually provide only a temporary reduction in symptoms.
