Spinal Poliomyelitis - an overview | ScienceDirect Topics
Spinal poliomyelitis is the most frequent and is characterized by flaccid paralysis of muscles innervated by the motor neurons of the spinal cord. Bulbar poliomyelitis results from the destruction of neurons of the brainstem and can be fatal by causing respiratory or cardiac failure.
Polio - Wikipedia
Spinal polio, the most common form of paralytic poliomyelitis, results from viral invasion of the motor neurons of the anterior horn cells, or the ventral (front) grey matter section in the spinal column, which are responsible for movement of the muscles, including those of the trunk, limbs, and the intercostal muscles.

2024年6月20日 · Polio is an illness caused by a virus that mainly affects nerves in the spinal cord or brain stem. In its most severe form, polio can lead to a person being unable to move certain limbs, also called paralysis. It can also lead to trouble breathing and sometimes death. The disease also is called poliomyelitis.

2024年10月6日 · Noninfectious considerations include spinal cord infarctions, transverse myelitis, acquired axonal neuropathies, myasthenia gravis, and Lambert-Eaton myasthenic syndrome. Guillain-Barré syndrome is a common cause of acute flaccid paralysis, clinically differentiated from polio by ascending, symmetrical onset, sensory defects, and the absence ...

2024年5月1日 · Poliovirus-induced destruction of motor neurons of the anterior horn of the spinal cord and brain stem cells results in distinctive paralysis. The incubation period for nonparalytic poliomyelitis is 3 to 6 days. For the onset of paralysis in paralytic poliomyelitis, the incubation period is usually 7 to 21 days.
Polio: Virus, Causes, Symptoms, Transmission & Treatment
2022年8月5日 · Paralytic poliomyelitis happens when poliovirus attacks your brain and spinal cord. It can paralyze the muscles that allow you to breathe, speak, swallow and move your limbs. Depending on what parts of your body are affected, it’s called spinal polio or bulbar polio. Spinal and bulbar polio can appear together (bulbospinal polio).

2023年3月24日 · Polio is a highly contagious infection caused by the poliovirus. Most people infected with the virus develop no symptoms from it. However, in a small percentage of infected people, the virus attacks nerve cells in the brain and spinal cord, particularly the nerve cells in the spinal cord that control muscles involved in voluntary movement such ...

1998年1月12日 · Skeletal muscle injury induces retrograde axonal transport of poliovirus and thereby facilitates viral invasion of the central nervous system and the progression of spinal cord damage. The pathogenic mechanism of provocation poliomyelitis may differ from that of polio acquired in the absence of predisposing factors.
Poliomyelitis - PubMed
Poliomyelitis, often termed "polio," is an acute infectious disease caused by an enterovirus which damages the anterior horn cells of the spinal cord and brainstem. Progress to lower motor neurone cell death leads to disruption of motor units and subsequent muscle weakness or complete paralysis.
Polio: MedlinePlus Medical Encyclopedia
Brain or spinal cord involvement is a medical emergency that may result in paralysis or death (usually from breathing problems). Disability is more common than death. Infection that is located high in the spinal cord or in the brain increases the risk of breathing problems.
