Denervation is any loss of nerve supply regardless of the cause. If the nerves lost to denervation are part of neural communication to an organ system or for a specific tissue function, alterations to or compromise of physiological functioning can occur. [1]

Denervation atrophy is caused by peripheral neuropathies and motor neuron diseases. The most common motor neuron disease in adults is amyotrophic lateral sclerosis. In children, it is the autosomal recessive spinal muscular atrophy and its variants (see Chapter 9- Neurodegeneration).

This Special Issue presents some of the most recent studies on the skeletal muscle denervation. Skeletal muscle innervation comprises stable and functional nerve interactions with muscles via neuromuscular junctions (NMJ).

Feb 26, 2021 · Denervation changes in muscles or denervation myopathy can be observed in a number of settings and results from partial or complete loss of innervation. There is a wide spectrum of clinical manifestations: temporary or permanent; symptomatic or asymptomatic.

Dec 15, 2022 · Skeletal muscle denervation is caused by damage or injury to the nerves that supply a muscle. This can occur as a result of a number of different conditions, including trauma to the spine or a peripheral nerve. Denervation can also result from infection, inflammation, and certain medical procedures.

Denervation occurs when tumor damages a motor branch of a nerve and results in muscle paresis and eventual atrophy. The signal changes on MRI include hyperintense T2 signal and enhancement in the acute phase (see Fig. 8).

Denervation causes fiber atrophy and myosin heavy chain co-expression in senescent skeletal muscle. PLoS One. 2012;7:e29082. doi: 10.1371/journal.pone.0029082. [ DOI ] [ PMC free article ] [ PubMed ] [ Google Scholar ]

This review concentrates on the biology of long-term denervated muscle, especially as it relates to newer techniques for restoring functional mass. After denervation, muscle passes through three stages: 1) immediate loss of voluntary function and ...

Denervation atrophy, also known as neurogenic atrophy, refers to the shrinkage or loss of muscle tissue caused by the interruption or loss of nerve impulses to the muscles. It occurs when the nerves that innervate the muscles are damaged or severed, leading to a decrease in muscle size, strength, and function.

Abnormalities signifying denervation may be detected on MRI in cases of early PTS, such as diffuse high signal intensity, or atrophy and fatty infiltration in later stages of PTS.
