What Is The Cluster Of Nerve Cell Bodies Outside The Central Nervous System
If the immune system can aggressively attack and kill all peripheral nerves could the human body function with just the central nervous system?
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
Mostly peripheral: Cranial nerves have their cell bodies within the central nervous system (cns), but the majority of their length/"processes" are outside the confines of the cns. The myelin covering nerves inside, vs. Outside, the CNS is different, and cranial nerves are subject to disorders common to peripheral nerves. (the cell bodies can be affected by CNS disorders as well.). ...Read more
There isn't just one: There may not be just one nerve that brings heart pain to the brain. This is why people describe their heart attack symptoms so differently. Some people get nausea, sweating and a sense of "just not feeling right, " while others get the more classic chest and arm pain. Others may get extreme heaviness in the chest and shortness of breath. Thi suggests that different nerve pathways can be involved. ...Read moreSee 1 more doctor answer
Does serotonin cause muscular rigidity via its effects in the central nervous system or by binding to peripheral 5-ht receptors in the body?
Centrally: Overstimulation of primarily the 5-ht2a receptors seems the leading hypothesis currently. ...Read more
Yes: Multiple sclerosis (ms) is an autoimmune disease (body's defense system attacking itself) that involves the central nervous system. Central nervous is composed of the brain and spinal cord. Myelin sheaths protect and insulate nerve cells; in ms the myelin sheaths on the axons (longer parts of the nerve cells) are inflamed and damaged, leading to scar development seen in white matter of the brain. ...Read moreSee 1 more doctor answer
Which drugs? Attack?: Many drugs act on the brain, some because they are meant to, others as side effects. Very few drugs damage the cns. The ones that are known to cause permanent changes are alcohol and stimulants like cocaine/crack and methamphetamine when used for long periods. Tolerance to opioids and benzodiazepines takes a year or so to disappear completely, but the effects are thengone. ...Read moreSee 1 more doctor answer
