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

Nerve (Definition)

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

Can you tell me examples for central nervous system, peripheral nervous system, somatic nervous system?

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! ...Read more

What are the difference between central nervous system and autonomic nervous system?

What are the difference between central nervous system and autonomic nervous system?

What they control: The central nervous system refers to the brain and the spinal cord. The autonomic nervous system is a part of the peripheral nervous system that is involved in processes related to heart rate, sweating, blood pressure, and other processes that we don't think about, aka the name "autonomic". Autonomic nervous system disorders include fainting, fast heart rate, fatigue and sweating disorders. ...Read more

Does drugs attack the central nervous system?

Does drugs attack the central nervous system?

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 more

Would activation of the sympathetic or parasympathetic nervous system lead to hunger?

Would activation of the sympathetic or parasympathetic nervous system lead to hunger?

A PairofSympathetics: The answer could be made VERY complicated but, just to sort-of give an overall picture: if you are jagged-up by the sympathetic system, you won't have much of an appetite unless you're a shark on the make (well, a shark is a Chondrichthyte so technically doesn't have a sympathetic nervous system....whatever...), but if you are calmed down parasympathetically your juices will flow, ready to eat. ...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

Does triavil block dopamine receptors in the central nervous system?

Does triavil block dopamine receptors in the central nervous system?

Yes: Triavil is an old medicine that is not often used anymore. It's a combination of Amitriptyline and perphenazine. The latter is a neuroleptic (antipsychotic) medication that mainly acts by blocking Dopamine receptors in the brain. ...Read more

Does m.S. Only attack the central nervous system?

Does m.S. Only attack the central nervous system?

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 more

Will high BP disable the central nervous system?

Will high BP disable the central nervous system?

Stroke: The most common thing that happens to the central nervous system in high BP is hemmorhagic stroke or a stroke caused by a burst blod vessel. Also, certain vascular malformations, such as an aneurysm or avm could bleed and cause dangerous pressure on the brain. ...Read more

Which body system does brain tumor affect besides nervous system?

Which body system does brain tumor affect besides nervous system?

Depends on type: The type and location of the brain tumor may affect other body systems. For example, a pituitary tumor is a classic tumor that arises in the pituitary fossa. It can have profound effects on the endocrine system as it diplaces normal pituitary function. If the tumors are endocrine active-it can afffect growth or blood pressure. Tumors near motor areas can affect the musculoskeletal system. ...Read more

Do nervous system diseases always attack the myelin sheath?

Do nervous system diseases always attack the myelin sheath?

Various mechanisms: The classic neurological diseases that involve myelin are Multiple Sclerosis, and Neuromyelitis Optica. Both Alzheimer's and Parkinson's involve nerve cell dysfnctn, and resultant neurotransmitter deficiencies. Some peripheral nerve disorders attack the central axon, and are termed axonal neuropathies. ...Read more
