Most disorders of nervous system cell involve glia rather than neurons. Multiple sclerosis (MS) one ot the mylein disorders, is a good example of this principle.

Is it true that motor neurons receive nerve impulses from the central nervous system causing muscle fibers to contract?
It would be more accurate to say that the neurons transmit the impulses, rather than that they receive them.
Why do people with AL'S have all of their mental functions and senses intact?
Amyotrophic lateral sclerosis is a disease which affects the motor neurons, rather than the sensory system or the central nervous system.
What does salt does for the body?
Sodium (from sodium chloride) is indispensable for life because it is important for:- regulation of blood pressure, pH, blood volume, osmotic pressure- transmission of nervous impulse- correct neurons function
How many neurons were used by Albert Einstein in his life?
Albert Einstein's brain has been extensively studied, since his death, and it does not appear to have an unusual number of neurons. It seems that he just made better use of his neurons, rather than having more of them.
How is reflex handled in the nervous system?
I'm not positive, but I think that reflexes are controlled by the sympathetic nervous system (SNS). The sympathetic nervous system is part of the autonomic nervous system (ANS), which is part of the peripheral nervous system (PNS). The SNS is responsible for fight-or-flight responses. For example, if you see a shark coming directly at you, you decide to try to either get away from it (flight) or fight it off (fight). Reflexes are mediated by reflex arcs, which are neural pathways. Some sensory neurons pass directly to the synapse of the spinal cord, rather than the brain. This allows reflexes to occur relatively quickly.
What is meant by future tense?
A prediction that you will be rather nervous in the near future.
What functional differences are there among sensory motor and associative neurons?
Sensory neurons are specialized to translate many forms of input (light waves, sound waves, tissue displacement, molecules suspended in air or dissolved in saliva, and so on) into action potentials. Motor neurons carry commands to glands and muscles. Association neurons have neither specific sensory nor motor functions, but rather form bridges between the sensory and motor neurons.
Which are triggered by psychological factors rather than by any physical caus?
conversion disorder
A neuronal circuit that concentrates or directs a large number of incoming impulses to a rather small number of neurons is called?
Converging circuit
Who discovered synapse?
Santiago Ramón y Cajal was a Spanish neuroscientist who demonstrated that neurons were not associated with each other in continuity, but rather in contiguity. The English neurophysiologist, Sir Charles Sherrington, and his colleagues named the contact between neurons a "synapse." The space between neurons revealed by Ramón y Cajal is now called a synapse.
What illness is A D D?
attention deficit disorder may be a condition rather than an illness
What disorder is characterized by binging and purging?
It's not an eating disorder 'caused by', but rather 'classified by' and it is known as Bulimia Nervosa. Google it.
