Nerves
Nerves are thread-like structures that form a network of pathways that transmit information from the brain to the body and the body to the brain, in the form of electrical impulses.

What are the functions of the neurons?
the function of neurons is to receive information, process it, and pass it on to other neurons, or muscles or endocrine/exocrine glands. I realize 'receive information, process it, and pass it on' is a giant and amorphous description, but the description of the behavior of organisms with neurons is also giant and amorphous.
Where does an action potential start?
Action potentials are generated on a part of the neuron called the 'axon hillock' - the proximal most portion of the axon.
How do you disable your nerve system without killing or paralyzing yourself?
Once you're close friends with a fire bender, earth bender, water bender, or air bender, and you can't bend, you'll figure out a way to do non bending things, like locating people's pressure points and hitting them to disable their nerves. Hope this helps.
The short answer is no.
reason being the speed of transmission has more to do with the medium(the thing it travels through) then the actual wave signal itself, so unless they found a way to completely reconstruct your nervous system with a different material it's pretty much impossible.
regardless, the speed at which the signals travel are already faster than you think.
most of the time spent in your reflex actions is at the brain or muscle level, so what you are asking for really isn't an amplifier for brain waves to travel faster, but rather an amplifier that allows your muscles to move faster.
Even if something like that is invented, there'd be a limit to how much speed you could gain as well.
For example, maybe it'd be possible for you to be as strong as a bear, pound for pound, you'd never be literally as strong as a bear in your current body size. in fact, if you were to possess such great strength with your current muscles, you'd rip your own arm off every time you swing it with full strength.
Severe anxiety, stimulated by external factors and the strong emotions you were feeling fueled your anger, and probably caused such reaction. No expert on the matter, but sometimes being aware of your reactions and acknowledging their causes and outcomes may help you gain control over it if it reoccurs. Taking heavy breaths upon realizing it and staying hydrated can help aswell.

Can optic nerve impulses only be interpreted as light?
There are two types of sensory receptors: rods and cones. Rods detect light, and cones detect shape.
What are the thread like structures that cointain genes called?
The thread-like structures that contain genes are called chromosomes. Each chromosome is made up of DNA tightly coiled around proteins, which help package and manage the DNA. Humans typically have 23 pairs of chromosomes, with one set inherited from each parent, containing the genetic information necessary for development and functioning.
Who has faster reflexes adults or teenagers?
We (not mentioning the exact names) have done a test on who has the faster reflexes and we have come up with an answer. We tested their reflex times by asking 10 students and 10 adults to turn on and off a specific timer as fast as they could. The slower the reflex time ( i.e.- 45) the slower the reflex. The faster the reflex time (19) the faster the reflex. When we tested the adults ( surprisingly) they had MUCH faster reflex times than the kids. Even though you'd think the opposite. The age categories were under 15 (kids) and over 15 (adults) so there's the proof.
False!
How does the long axon help in a nerve cell?
The axons are long so that action potentials can be sent from one part of the body to another very quickly. If instead of one long axon we had loads of individual cells there would be a much bigger delay because the action potentials would have to be converted to chemical signals very fequently and that takes time.
What are examples of smooth muscles?
kidneys, stomach, intestines, bladder, the eyes, the walls of blood vessels. Smooth muscles that are sometimes called visceral muscles. They are thin muscles that look like spindles. They can be found in your skin and your blood vessels and your organs inside your body.
repolarization
Which part of the neuron can carry information for long distances?
The axon is the part of the neuron that can carry information for long distances.
How is the message caried from one neuron to another it there is a space between them?
The synaptic gap is the space between the dendrites of one neuron and the axon of the next. The impulse is carried across this space by chemicals called neurotransmitters which conduct the electrical impulse.
What does a disc protrusion impressing upon a ventral surface of the cord mean?
The only time you really need surgery to correct this condition is when the disc herniates and occurs at an angle of roughly 45-60 degrees off either side of the disc [when looking down at the disc from above, the back is at the bottom and the 'stomach' is at the top]. What happens then is that the disc can compress one of the spinal nerves as it exits the spinal column. If this occurrs in the neck or the lower back [lumbar area] you can have pain and impairment of the area serviced by that nerve. I've never seen a nerve impingement in the thoracic area, and they are really rare.
If the disc bulge is midline, there isn't enough of it to compress the spinal cord IN THE LOWER BACK... In the neck there can be some cord impingement and problems... If the disc bulge in toward the 'stomach', there is nothing to worry about as no nerves are affectable in that direction.... The key is spinal cord involvement or individual nerve root affectation...
The only time surgery should be contemplated is if a nerve root is compressed severely enough that muscles can be permanently effected...
About 75% of the time a herniated disc will shrink and heal itself after 3-6 weeks have passed...
