Answer:
Explanation:
Action potential
It is the potential or power or electrical energy required to generate impulses and provides communication between the neurons is called action potential. Normally cell membrane consists of potential is called resting membrane potential() -70mV. The action potential is due to exchange of different ions across the membrane.
Phases of the action potential in a neuron are
i. Depolarization- it is caused by the influx of sodium and calcium ions through the opening of voltage-gated sodium and calcium channels. sodium ion influx is rapid than the calcium ions membrane potential -70mV to +30mV.
ii. Repolarization - It causes the efflux of potassium ions into the cell through the opening of potassium channels. the membrane returning to resting membrane potential.
iii. After- Hyper polarization - in this stage the potassium channels remain open and causes re polarization and comes to normal membrane potential.
The generation of impulses(depolarization) in neuron mainly depends on influx sodium and calcium ions without these ions, no action potential developed and neuron firing does not occur.
If the drugs inhibit these channels, no depolarization, no action potential, no neuronal firing or communication.
The channels involved in an action potential are voltage-gated sodium channels, potassium channels, and calcium channels.
The action potential is required for transmission of information one are to another area in the body.
The responses to different stimuli is due to action potential.
The correct answer to this open question is the following.
Unfortunately, you forgot to attach the political cartoon. Without the cartoon, we do not know what is its content.
However, trying to help you, we did some deep research and can comment on the following.
This cartoon depicts a hammer and an anvil. White hands are holding the hammer that is hitting a chain. A black arm is chained. So the white hands using the hammer are hitting the chains, breaking them. The hammer has a legend that says "Supreme Court Decision." The chain says "segregated schools."
So the purpose and symbolism of the cartoon of 1954 are the following. It refers to the Supreme Court decision in Brown v. Board of Education of Topeka of 1954 case. The Court ruled that segregation in public schools was unequal and was unconstitutional. The Court concluded that in public education “separated buy equal” was not correct. It was a major accomplishment for black people in those years.
