Extracellular calcium is the primary regulator of PTH secretion from the parathyroid gland. The fusion of secretory vesicles with the presynaptic plasma membrane.

<h3>What is meant by extracellular calcium?</h3>

Extracellular calcium is the primary regulator of PTH secretion from the parathyroid gland. In mammals and birds, the circulating levels of PTH are greatly altered by minute changes in the blood calcium concentration.

Even before calcium was identified as the trigger for exocytosis, reductions in extracellular calcium were known to increase the likelihood of action potential initiation (Frankenhaeuser and Hodgkin, 1957) by altering the properties of the neuronal ion channels.

Calcium from extracellular sources is necessary to maintain many cell types' metabolic processes. The calcium-sensing receptor (CaSR), which is located on the plasma membrane, allows cells to respond to these changes.

swat32

<u>You need to stay current with local news</u> in order to respond to questions like this. Boycotts and protests are extremely common occurrences; mainstream media, local media, and even alternative media outlets regularly cover them.

"Touch the grass," as the saying goes, implies to observe outside of your comfort zones. Get off the internet and interact with individuals who are fighting for their human fundamental needs such as adequate housing, wage increases, accessible healthcare, climate justice, cheaper costs for essential necessities like gasoline, and so on.

To provide evidence or examples in history, we can trace the 8-hour workday of today's workers back to earlier labor movements of various unions. Because of these labor movements, we despise child labor. Previously, workers' boycotts and strikes had a significant impact on how we opposed cruel capitalistic ways.

Power of the people to organize themselves to protect each other helped people create change successfully.

There's nothing wrong with knowing about the history of struggles in your own nation and siding with the downtrodden rather than looking aside and empowering the oppressors.

Write a speech that Theodora might have given Justinian to convince him to stay in Constantinople during the rebellion in A.D 53
const2013 [10]

Allow me to do better than offer "a speech that Theodora <em>might hav</em>e given."

The following is a record of the speech she <em>actually did give</em> to Justinian in AD 532, when the riots had broken out in Constantinople.

The speech was recorded by the historian (AD 500-565), probably on the testimony of one or more of the royal advisors who were present.  Procopius recorded Theodora's words in chapter 24 of his <em>History of the Wars </em>(published AD 552).  Here's what he said Theodora said to Justinian:

  • <em>As to whether it is unseemly for a woman to be bold among men, or to be daring when others are full of fear, I do not think that the present crisis allows us to consider the matter.  For in extreme danger the only vital thing is to deal with the situation in the best way.  For my part, I consider that now of all times flight would be bad, even if it brings safety.  Once a man is born he cannot escape dying, but for one who has held the imperial power it would be unbearable to become a fugitive.  May I never be parted from this purple, and may I never live to see the day when men who meet me will not address me as their sovereign.  If you wish to be saved, Emperor, that is not difficult.  We have great resources of wealth; there is the sea, here are the boats.  But take care lest when you have saved yourself you wish that you could have death instead of your safety.  I agree with the old saying, “Purple is a good shroud.” </em>
