When the second excitory postsynaptic potential arrives at a single synapse before the effect of the first has disappeared what occurs?
Temporal summation occurs at a single synapse that is activated by a second excitory postsynaptic potential occurring in rapid succession before the first has disappeared.
If an animal from food chain is disappeared then what will be its effect on the food chain?
it would effect the food chain because one part of the food chain is missing
What accomplishes the transmission of the nerve signal across the synapse?
The release of 'neurotransmitter substances' from an axon's perifery which traverse the synaptic cleft - the space between axon and adjoining dendrite - to both affect and effect the adjoining dendritic "perifery" which then re-initiates signal propagation to the next bunch of exonic nerve "endings".
Isolating mechanisms that take effect before or during fertilization are termed?
prezygotic
What is the difference between action potentials and synaptic potentials?
A synaptic potential exists at the INPUT of a neuron (dendrite), and an action potential occurs at the OUTPUT of a neuron (axon). (from OldGuy)(from Ilantoren:) A synaptic potential is the result of many excitatory post synaptic potentials (epsp) each one caused by the synaptic vesicles released by the pre-synaptic terminus. If there are enough of these epsp then the responses will summate and depolarize the post-synaptic membrane at the axon hillock enough to fire an action potential.
When the second excitory postsynaptic potential arrives at a single synapse before the effect of the first has disappeared what occurs?
Temporal summation occurs at a single synapse that is activated by a second excitory postsynaptic potential occurring in rapid succession before the first has disappeared.
What is the relationship between the action potential and the synapse?
A synapse and an action potential have a flip-flopping cause and effect relationship, in that an action potential in a presynaptic neuron initiates a release of neurotransmitters across a synapse, which can then subsequently potentially trigger an action potential in the axon of the postsynaptic neuron, which would then cause release of neurotransmitters across a following synapse.
How does nicotine effect cells?
Nicotine is a Sympathetic drug when it acts on synapse it has its Sympathomimetic action and it activates the neurons.
Numerous nerve impulses arriving at a synapse at closely timed intervals exert a cumulative effect?
temporal summation
Effects of drugs on the nervous system?
The effect of the drug ecstasy causes a build up of serotonin at the synapse gap. This is because the ecstasy causes a blockage at the receptor molecules, meaning the synapse chemicals (serotonin), are unable to be 'absorbed' by the receptor molecules.
If an animal from food chain is disappeared then what will be its effect on the food chain?
it would effect the food chain because one part of the food chain is missing
What would happen if the ionosphere disappeared?
One significant effect would be that long range radio communication by shortwave would be impossible.
What country did the end of the Vietnam war effect?
Only one nation was ultimately effected permanently: The Republic of South Vietnam disappeared! There is no such country today.
What means cause?
It's what happens before the effect!
What does it mean that a piece of cause and effect writing must be sequential?
It means that the cause must come before the effect. For example, the stoplight turns red (cause) before the car stops (effect), so the cause is written before the effect. Linear order.
How did the first bicycle effect peoples lives?
Before the average guy could afford a car a bike extended the distance a person could travel from home to work or whatever considerably.
Which of the following is not true of cause-and-effect relationships?
The effect occurs before the cause.
