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.
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.
Through spinal nerve: Most peripheral nerves connect to the CNS via the spinal cord. Some through autonomic chains.
Can you tell me examples for central nervous system, peripheral nervous system, somatic nervous system?
OK: 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!
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.See 1 more doctor answer
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.
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.
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.
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.See 1 more doctor answer
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.
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..
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.
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.
I do Not think EMG or NCS are reliable or accurate for analyzing Peripheral nervous system what limitations do these tests investigations have?
Would love to asnwer: You have just asked about 12 months of training in Neurology residencies!!
