Patient discussion about neuraxis

Q. Fibromyalgia deeply affect the CNS? Do fibromyalgia deeply affect the CNS (central nervous system)?

A. Fibromyalgia is somewhat related to central nervous system. Fibromyalgia can ultimately disrupt the flow of neurotransmitters between the body and the brain. As a result, fibromyalgia can cause the patient to feel continuous pain, and create chronic muscle spasms. In addition, fibromyalgia patients are often subject to abnormally light a sleeping pattern which prevents the normal production of serotonin and growth hormone normally produced during stage 4 (deep) sleep. This inhibits the body’s ability to heal itself, and may contribute to the overwhelming fatigue and depression experienced by those with FMS.

Q. Is fibromyalgia related to Central Nervous System? Is fibromyalgia related to Central Nervous System? Among men and women who is more prone to the symptoms of fibromyalgia?

A. here is a quote from the National Fibromyalgia Association site:

"Little research has been conducted that measures the prevalence of fibromyalgia, and estimates vary widely as to the proportion of male versus female patients. A 1999 epidemiology study conducted in London found a female to male ratio of roughly three to one. However, a 2001 review of the research literature in Current Rheumatology Reports stated the ratio was nine to one."

Similar to PA, PMAs are most commonly located in the hypothalamic/chiasmatic region, although they can occur in other locations in the neuraxis (26).
The study proposed that there is a functional and anatomically interconnected network of brain regions located at every level of the neuraxis. Beginning at the spinal and brainstem autonomic nuclei, and extending to cortical regions that integrate emotional and cognition with information regarding bodily states.
This tumor very rarely occurs outside the central neuraxis. After reviewing the English literature, we found a total of 12 cases of sporadic HBs arising in soft tissues, including the present case.
The extent and severity of the neurological deficits depend on the location of the lesion along the neuraxis [22].
In addition to the position along the neuraxis, the fate of single neurons depends on many factors including epigenetic profile and patterning factors.
The ENS arises from the neural crest, mostly from the vagal levels of the neuraxis. The enteric neural crest-derived cells (ENCDCs) invade the foregut and migrate along the gut wall and then proliferate and differentiate until they colonize the entire bowel and become wired together by synapses to form a functional nervous system finally [9-11].

Our findings lay the basis for future attempts to decode the information obtained by mechanoreceptors and their associated TG neurons situated at the very beginning of the vibrissae-barrel neuraxis.
In addition, studies have demonstrated that NO has a complex and diverse role in the modulation of nociceptive processing at various levels of the neuraxis (34).
(10-11) The pontomedullary reticular formation receives nearly 90% of the output dedicated to the neuraxis and cortex modulation, ipsilaterally.
Both DBH and TH were used to reveal the norepinephrine expression not only in locus coeruleus neurons, but also in the NE axons or fibers across the entire neuraxis [34,35].
