They found that these sensory fibers wire together in the spinal cord with another group of neurons known as RORα neurons, named for a specific type of molecular gate found on each cell's nucleus.
The extensive nerve network in the submucosa contains visceral sensory fibers mainly of sympathetic origin, parasympathetic (terminal) ganglia, and preganglionic and postganglionic parasympathetic nerve fibers.
Sensory fibers of the median nerve and motor fibers of the deltoid and biceps muscles are affected in upper trunk lesions of the brachial plexus and motor fibers to the triceps muscles are affected in middle trunk lesions of the brachial plexus unlike TOS.
Fuh proposed that the underlying mechanism for the co-morbid association could be the "activation of sensory fibers within ectopic endometrial tissue, [leading] to hyperactivity of neurons throughout the central nervous system.
UCLA researchers Sandra Rieger and Alvaro Sagasti found that hydrogen peroxide, a chemical signal released by wounded skin cells promotes the regeneration of sensory fibers, thus helping to ensure that touch sensation is restored to healing skin.
