What Is a Motor Neuron?

Motor neurons are external neurons. Motor neurons are neurons responsible for transmitting information from the spinal cord and brain to muscles and endocrine glands, which govern the activity of effector organs.

The concept of motor unit was first proposed by Sherrington, which refers to the combination of a motor neuron plus a group of muscle fibers that it controls. For convenience, a group of muscle fibers innervated by a single motor neuron is also called a muscle unit. Generally, in any adult animal, the outer striated muscle fibers of a muscle spindle are dominated by only one oral motor neuron, so the motor unit is a functional unity and a quantum unit of motion. All muscle fibers innervated by an a motor neuron exhibit the same histochemical properties and are also believed to exhibit the same mechanical properties. ^[1]

The etiology of this disease is unknown. Some scholars believe that it is caused by chronic viral infection. After the onset, the disease is slowly and progressively exacerbated. However, it can be treated with nerve growth factor or cell growth peptide intramuscular injection. Complications occurred later. However, if you can take good care and strengthen symptomatic and supportive comprehensive treatment, you can greatly relieve symptoms and prolong life. Advise patients and their relatives, because the diagnosis and treatment of this disease is relatively strong, after the onset of disease should go to a conditional neurological specialty diagnosis and treatment, do not trust the social travel doctors, so as to avoid misdiagnosis and mistreatment and waste money.

Prognosis of motor neuron motor neuron disease

This disease is a progressive disease, but the course of disease varies between different types of patients, even if the progress of the same type of patients is different. The average course of amyotrophic lateral sclerosis is about 3 years, and it can even die within 1 year after the onset of onset, and the course of slow progress can sometimes reach more than 10 years. Adult-type spinal muscular atrophy generally develops slowly, and often lasts for more than 10 years. Idiopathic lateral sclerosis is rare clinically and generally develops slowly. Most of the deaths were caused by bulbar paralysis, respiratory muscle paralysis, combined with pulmonary infection or general failure.
