What are chemicals which relay amplify and modulate between a neuron and another cell?
Neurotransmitters are chemicals that send messages from one cell to another.
What term refers to a neurotransmitter?
are endogenous chemicals which relay, amplify, and modulate signals between a neuron and another cell.[1] Neurotransmitters are packaged into synaptic vesicles that cluster beneath the membrane on the presynaptic side of a synapse, and are released into the synaptic cleft, where they bind to receptors in the membrane on the postsynaptic side of the synapse. Release of neurotransmitters usually follows arrival of an action potential at the synapse, but may follow graded electrical potentials. Low level "baseline" release also occurs without electrical stimulation.
What is difference between electronic and electrical?
flow of current through conductor called electrical ( example - copper, aluminum ) flow of current through semi conductor called electronics ( example - silicon, germanium ) Electronics also includes use of vacuum tubes and other technologies that can amplify and/or modulate signals. Electrical circuits lack the ability to amplify or modulate (note: a transformer that steps up voltage is not amplifying as there is power lost that cannot be made up; an electronic amplifier that raises the signal's voltage does not cause loss of power in the output signal as it can take power from its power supply as needed, it may even raise the signal power as well as voltage).
What is the purpose of neurotransmitters-?
A neuron is a cell that is in the brain and it contains neurotransmitters. They are released from one neuron in order to send a message to another cell.
When was The Chemicals Between Us created?
The Chemicals Between Us was created on 1999-09-14.
What is the difference in function between basophils and eosinophils?
basophils release anti-inflammatory molecules including histamine and herapin eosinophils just modulate the inflammation process
What is difference between ac and DC amplifier?
AC amplifiers are used to amplify AC signals and use components that handle large voltage values. DC amplifiers are used to amplify DC signals which use small powered electronic devices.
What the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
Why might a mast-mounted amplifier be preferable to an amplifier right at the TV set?
The mast mounted amplifier will amplify only what is coming out of the antenna, while a set located amplifier will also amplify any noise that was induced in the lines between the mast and the set.
How an operational amplifier can amplify DC signals?
It takes the difference between of two input and amplify by the open loop gain of the amplifier or closed loop gain of the amplifier. It is very hard to control open loop gain of 100 Db so it very seldom used
How a battery provides energy to a circuit?
In very simple terms, there are two chemicals in a battery - one chemical wants more electrons and the other chemical wants to get rid of electrons. When a path (i.e. circuit) is completed between the two of them (the ends of a typical AA, AAA, D, etc. battery or the two posts on a 9V battery, the electrons are free to move from one post to another. The movement of electrons is current. Different chemicals and/or configurations determine how badly the electrons want to get from one chemical to another. That drive to get from one to another is called voltage potential, and is expressed in volts. How fast the electrons travel between the two chemicals is the flow, or current, and is expressed in Amperes or Amps... for small batteries, it is usually expressed in milliamps because the current is so low. The capacity of the battery is expressed in milliampere-hours which is how many amperes can flow between the chemicals over a given amount of time until the chemicals have exchanged so many electrons that the electrons no longer have any drive to flow between the chemicals anymore.
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.
