Which part of the nervous system is control by 75% of the vagus nerve?

Which part of the nervous system is control by 75% of the vagus nerve?

Please clarify: Frankly, I have no idea what your post means. The vagus nerve is PART of the nervous system. It's part of the parasympathetic nervous system. Maybe if you posted what led you to ask the question I could figure out what you mean because right now I haven't got a clue. It's like asking, "Which part of the car is control by 75% of the windshield?" ...Read more

Autonomic Nervous System (Definition)

The autonomic nervous system is part of the peripheral nervous system. It is ‘autonomic’ because it does not require voluntary thought to function. The autonomic nervous system is divided into the sympathetic and parasympathetic nervous systems. The sympathetic system manages “fight or flight” responses and the parasympathetic system acts as a counterpart that manages ...Read more

What reflex is independent of the central nervous system (CNS)?

What reflex is independent of the central nervous system (CNS)?

More than I can list: With which organ system outside the BRAIN & SPINAL cord do you wish to start? What's the clinical context of the question so I can better understand the purpose of the question. This forum is basically for questions of a general clinical nature and what you ask seems to be for more academic purposes. ...Read more

Where is autonomic nervous system located? Is there cranial nerve which regulates dialation/constriction of the blood vessels?

Where is autonomic nervous system located? Is there cranial nerve which regulates dialation/constriction of the blood vessels?

Throughout the body: The autonomic system includes the sympathetic and parasympathetic systems. Sympathetic nerves exit the thoracic & lumbar cns, parasympathetic exit the cranial & sacral cns. They then go to organs throughout the body. College lecture on this: http://www.Youtube.Com/watch?V=erlvvlqoaow. ...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?

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?

Neuropathy: Interesting question, autoimmune neurological peripheral disorders can be aggressive and progress fast but usually start with tingling and loss of sensation before paralysis. Are you asking about a specific disorder or a hypothetical question? ...Read more

What carries impulses between the peripheral nervous system and the CNS?

What carries impulses between the peripheral nervous system and the CNS?

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

What is the difference between the central nervous system and the peripheral nervous system?

What is the difference between the central nervous system and the peripheral nervous system?

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

Can you compare the somatic nervous system with the autonomic nervous system?

Can you compare the somatic nervous system with the autonomic nervous system?

Nervous system: somatic nervous system is under your control, example making given him smoking up and down. Autonomic nervous system not to not under voluntary control, example your heart rate and blood pressure are dramatically controlled depending on the needs of the body, your interest and will move by peristalsis, movement of the bowels ...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

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

Is there a part of the brain that controls blood pressure?

Is there a part of the brain that controls blood pressure?

No: There is no certain brain part that controls blood pressure. Blood pressure control is multifacet mechanism but is primarily regulated by so called "baroreceptors" in the vessel wall. Those receptors are able to detect the degree of the vessel wall stretch and react to it accordingly. This triggers a whole cascade of other mechanisms of BP regulation. ...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?

If the immune system can aggressively attack and kill all peripheral nerves could the human body function with just the central nervous system?

No: The central nervous system relates to the brain and spinal cord. To reach the targets (skin, muscles, blood vessels, etc) you need the peripheral nervous system. You would be paralyzed and die without it. ...Read more

Autonomic (Definition)

The autonomic nervous system (ans or visceral nervous system or involuntary nervous system) is the part of the peripheral nervous system that acts as a control system functioning largely below the level of consciousness, and controls visceral functions, such as heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, ...Read more
