The chemical element important for signal transmission in nerves is?
Well, there are several. It takes sodium and potassium involved in polarization of the neuronal membrane, and then, of course, there is NO transmitter release without calcium. So, those 3 would be absolutely essential.

Maybe sodium> http://www.dummies.com/how-to/content/un... Signal transmission in a nerve is a bit complicated.
Components of nerve signal transmission via a chemical synapse?
Place them in the correct order: a Vesicles containing neurotransmitter are emptied b The signal reaches receptors on the postsynaptic neuron c The nerve signal is carried down the axon of a presynaptic neuron d The nerve signal reaches the presynaptic knob e Neurotransmitter molecules traverse the synaptic cleft
Can anyone help me with my Chemistry homework? Please and thank you. :)?
List at least 6 other elements other than Hydrogen, Carbon, Oxygen, and Nitrogen that are found in the body and descride one way in which each is important to body functioning.
What are the compositions of mineral water?
Here you could have a rough idea of mineral water compositions.Calcium plays a major role in our bodies, strengthening bones and teeth, but this bone-building mineral is also significant in other areas of our health, including weight management and warding off PMS.Magnesium and other minerals absorbed into the body are utilized as “ions” and circulated throughout the body via the blood. There, magnesium is used by our cells in order to perform routine functions such as creating energy, building hormones, maintaining cells, and bodily movement.Sodium helps muscles and nerves work properly by assisting muscular contraction and transmission of nerve signals. It also helps regulate blood pressure and volume. The proper amount of sodium in the body maintains an appropriate overall balance of bodily fluids.The health benefits of potassium include relief from stroke, blood pressure, heart and kidney disorders, anxiety and stress, as well as enhanced muscle strength, metabolism, water balance, electrolytic functions, and nervous system.Bicarbonate is a major element in our body. Secreted by the stomach, it is necessary for digestion.sources: Google.
Why are neurotransmitters important for nerve impulse?
Neurotransmitters are basically a mode of communication between 2 neurons (cells with only sole purpose to receive, digest and forward the information).So when the orders are released from central command (brain or spinal cord) → they are carried by the vast network of neurons → but in most cases, neurons don’t talk to each other directly (maybe they have ego problem) → so ones these messages reach the end of a neuron, they employ the services of various Neurotransmitters → neurotransmitters understands what they have to do exactly -whether this is stimulators or inhibitory message → dive in and try to cross the river of post synaptic → ones they reach the other neurons, they stimulate the appropriate receptors (stimulators or inhibitors), so that the message is conveyed to the other Neurons → this process is continued till the receiver organ gets the message.Basically they are small chemical messengers which plays a big important role of playing as a channel of communication between neurons, in transmitting the message from brain to various organs or tissues.Hope this helps.Neurotransmitter - Wikipedia
How does electricity transmit information in the brain?
Information is communicated by the spatial and temporal structure of electrical impulses as represented by action potentials [1]. Since action potentials are "all-or-none" events, postsynaptic neurons only "know" the relative timing of the action potential of an individual neuron, rather than the magnitude of the action potential.With that said, neurons can still transmit a lot of information by both temporal and population codes. By temporal codes, I mean the distribution of interspike intervals, or intervals between each consecutive spike of a neuron. From 20 spikes, you can choose a huge variety of interspike intervals - all that could theoretically represent a different bit of information (although in practice, neurons usually don't carry *that* much information). The simplest temporal codes are used by motor neurons, which just use rate coding, or number of action potentials per second (http://en.wikipedia.org/wiki/Rat...), to carry information about intensity.What's more important (in the brain, at least) are the population codes (which can represent whether surrounding neurons are synchronized or not). If two nearby neurons frequently fire together (or are frequently correlated with each other), for example, they will often trigger long-term potentiation in the postsynaptic neuron, in which case the information belonging to each presynaptic neuron gets "associated" with each other.Also, population codes can use combinatorics to encode more information. If you had 2 neurons that fired in response to certain faces, you could encode up to 4 faces, depending on whether or not they fired at a particular time or not. If you had 10 neurons, you could encode up to 2^10 faces. (see Christof Koch's The Quest for Consciousness - chapter 2)In any case, you often have enough neurons whose firing patterns are correlated with each other, such that their voltage fluctuations can be measured by an EEG (http://en.wikipedia.org/wiki/Ele...). One distinct type of voltage fluctuation, for example, is the alpha wave, as shown below[1] Also see the book Spikes: http://www.amazon.com/Spikes-Exp...and http://en.wikipedia.org/wiki/Neu...
