What is the HPA axis and how does it control cortisol? Please draw a diagram

Expert Solution

ANSWER: HPA axis - Hypothalamus, pituitary, Adrenal gland - When these three are co-ordinating and performing in the body is called HPA axis. In that way it will control the cortisol hormones.

Cortisol hormone- It is the stress hormone, due to some issues our body will attain stress stage, in that time cortisol hormones released in the blood stream and maintain the body in normal stage.

How it control - when our body in stress our brain (hypothalamus) send signal to the pituitary gland by secreting hormones called CRH- corticotrophin releasing hormones.

when this hormone released to pituitary gland, they will come to know that our body in stress so it will secretes hormones called ACTH - Andreno corticotrophic hormone to the kidney. So cortisol is the hormone secreted in the kidney.

And kidney will releases the hormone and maintain the body during stress period.

In the space below, draw a firm’s isocost/isoquant diagram with K on the vertical axis and L on the horizontal axis. Show the change that would occur if capital became more expensive and the firm maintained the same total cost. Be sure to show how each curve changes. To the right of the graph, clearly indicatewhat happens to the level of output and use of both L and K, and whether you are showing L and K as substitute inputs or complementary...

What might happen to blood pressure if epinephrine is administered alone. Draw a typical control diagram, identify and state the purpose of each reflex component, and indicate whether positive or negative feedback is responsible for restoring blood pressure. How does that control system differ with the addition of atropine?

Draw a diagram where you display output Y on the y-axis and physical capital K in the x-axis. Draw all the relevant curves for analyzing the Solow-Swan model and explain in words what each of those describes. Assume that the economy starts at steady state and is then hit by a shock that increases the saving rate. Point out what the new steady state levels of capital and output are. Do they increase or decrease? Why? Explain in words the...
