What Is The Difference Between Central And Peripheral Nervous System
Just that: The division of your nervous system into central & peripheral is based on anatomy, not physiology. . The brain & spinal cord make up the central; the continuation from these two make up the peripheral. But they are continuous. The ''third" nervous system regulates the function of your remaining organ systems, from bowel to cardiovascular & everything in between. Maintains balance. ...Read more
Anatomical terms: Brain, spinal cord, and cranial nerves, especially optic nerves, all start within the central system. Once outside the spinal canal these nerves are now called peripheral nerves and connect to muscle to cause contraction, and return to spinal cord, sensory nerves, to report peripheral sensations from outer world. ...Read more
Through spinal nerve:
Most peripheral nerves connect to the CNS via the spinal cord.
Some through autonomic chains. ...Read more
Can you tell me examples for central nervous system, peripheral nervous system, somatic nervous system?
Central nervous system — brain & spinal cord
Peripheral nervous system — all the nerves that come out from the brain and spinal cord. Within the peripheral nervous system you have 'somatic' and 'visceral' nervous systems. Somatic refers to muscle, skeleton, skin. Visceral refers to internal organs. In a nutshell! ...Read more
Is it the central or peripheral nervous system problem if you get back pain with sensations going down a leg?
Describing sciatica: Peripheral nerve compression. As the nerves leave the spinal column the "disc", a tough, fibrous, shock absorber that is between the vertebral bones can extrude and press on the nerve in a few places. This is usually "self-limited" meaning it goes away over time with stretching, nsaid's like ibuprofen, and traction(gravity boots). Usually no images(x-ray, ct, mri) needed unless weakness, bladder, bowel, chang. ...Read more
Do most neurological disorders usually affect the central nervous system or the peripheral nervous system?
Both: There are conditions that only affect the central eg stroke, or peripheral or both. ...Read more
Peripheral nerves...: The peripheral 'wiring schematic' begins at the nerve roots exiting the spine (at the anterior horn cell, to be specific), which then travel through a plexus (one on each side of the pelvis, and one under each collarbone), which emerge as peripheral nerves into the arms & legs, terminating at the junction with an organ (such as muscle or skin). Head and neck nerves differ slightly. ...Read more
Possible peripheral nervous system disorder maybe as suggested on Health Tap. What type of Dr should I see?
Nervous system: Not sure what disorder u r referring to, but a Neurologist would probably be good option. ...Read more
In a very rare disorder has a neuro come across when certain cells have attacked and killed the peripheral nervous system leaving the body to die?
Definitely yes: It is well-known that alcohol is a depressant of the CNS and vascular system, leading to irreversible changes in the peripheral nervous system. Additionally, there is a direct neurotoxic effect of alcohol. The most frequent consequence of chronic alcohol intake is a toxic alcohol induced polyneuropathy. The symptoms include numbness of the soles, followed by discomfort of feet and legs. ...Read more
Many: There is a whole sub-specialty area of neurology called neuromuscular disease that diagnoses and manages all the diseases that affects the peripheral nervous system. There are many diseases in this area and can cause pathology of the nerves and the muscles as well as the connection between the two. It is numerous to list them all here. ...Read more
Brief anatomy: Sensors in the skin pick up pain, temperature, light touch, carry along peripheral nerves that synapse within the spinal cord, travel up anatomical pathways into the brain and at level of thalamus, pathways to grey matter via white matter connections eventuate in conscious awareness. Recommend textbook of medical physiology for more information. ...Read more
If the immune system mediated an aggressive attack on the whole peripheral nervous system and killed the entire nerves of the body what are symptoms?
Death: Although i just answered your question, important to understand that this would involve a rare progressive irreversible anaphylactic allergic reaction, and this really affects numerous organ systems. However, consider that there are chronic immune disorders that attack peripheral nerves (cidp), and nerves in central brain and spinal cord (ms). This is almost never an all or none situation. ...Read more
Not selectively: Antibodies circulate in blood and diffuse into the interstitial fluid and from there into any cells these molecules come into contact with. However, neurons are not specific targets of the antibodies, except in case of some auto-antibodies directed at neural tissue. ...Read more
I do Not think EMG or NCS are reliable or accurate for analyzing Peripheral nervous system what limitations do these tests investigations have?

Can the immune system attack directly peripheral nervous system go beyond mylein sheath and destroy the whole of the nerve?
Neuropathy: Yes. Immune mediated neuropathies can occur where the primary target is the myelin and the process is so severe that axonal injury (nerve core) can occur. Immune response primarily directed to the axon (nerve core) cam also occur and are typically more severe and less likely to recover from. Secondary myelin injury always occurs in this type of axonal injury. ...Read more
If the immune system mediated an aggressive attack on the whole peripheral nervous system and killed the entire nerves of the body are you paralyzed?
Can your peripheral nervous system become oversensitive following a stressful event? I feel like I can feel my clothes on my body for months now.
What happens if the peripheral nerves are targeted in a severe immune response and kill the peripheral nervous system? Does the body shut down?
Depends on the nerve: What happens depends on the type of nerve affected by the immune response. If sensory nerves are affected there can be loss of sensation; if motor nerves are affected there can be weakness or paralysis. One example of this is guillain barre syndrome. Sometimes the autonomic nervous system is also affected leading to changes in pulse and blood pressure. ...Read more
Inability to control temps, Tachy Brady, aspiration, reflux. Geneticist suggested peripheral or central nervous system disorder. Like what?
Brainstem problem?: Speculating: Cardioacceleratory-cardioinhibitory nucleus is in the medulla oblongata. So is the nucleus ambiguus (control of pharyngeal muscles). The thermoregulatory center is distant, in the preoptic anterior hypothalamus, BUT descending fibers pass through the medulla because everything must. So it could be a multisystem CNS problem or localized to the medulla. Call in a pediatric neurologist. ...Read more
If the immune system can aggressively attack and kill all peripheral nerves could the human body function with just the central nervous system?
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
What kind of test can diagnose Peripheral neuropathy- Paraneoplastic syndromes of the nervous system?
Physical & labs: If physical exam suggests peripheral neuropathy, the workup will include assays for a few of the paraneoplastic autoantibodies known to cause it, and a diligent search for an underlying cancer should be undertaken. This is a difficult workup for physician and patient alike, and I wish you luck. Stay proactive. ...Read more
