… =Chronic over stimulation of sympathetic nerves induced by stress or cold.

Question 18 of 28

Question 19 of 28

What are the actions of resistance by cortisol? (7) =Cells that produce hormones made to affect distant cells.

Question 19 of 28

Question 20 of 28

What are the negative effects of cortisol action? (Overstimulation parasympathetic) = Hormones of paracrine cells that affect nearby cells.

Question 20 of 28

Question 21 of 28

What are the symptoms of sympathetic stimulation? =Hormones of autocrine cells that affect themselves.

Question 21 of 28

Question 22 of 28

Which two ways does the neuroendocrine system influence the immune system? =Water soluble / lipid soluble.

Question 22 of 28

Question 23 of 28

How does the immune system influence the neuroendocrine system? =Transport protein – diffuse through lipid bilayer – receptor protein – gene expression – MRNA (new protein)– cell activity.

Question 23 of 28

Question 24 of 28

What are the four F’s of the stress response? =Blood – receptor protein in membrane – g protein – adenyl cylase – ATP – cAMP – protein kinases – enzymes phosporylatend (reactions catalysed).

Question 24 of 28

Question 25 of 28

What are the negative impact of distress? =Converts ATP – cAMP.

Question 25 of 28

Question 26 of 28

What are the two types of stress? (2) =Phosphorylate enzymes.

Question 26 of 28

Question 27 of 28

--- =Catalyse reactions that change cell activity (physiological response).

Question 27 of 28

Question 28 of 28

What is the name of the syndrome of heart failure caused by stress? =Binds to G protein – chronic activation of ATP – cAMP – protein kinases, phosphorylated enzymes, catalysed reaction that dumps C1 from the cells – chloride ions draw water from body – chronic diarrhoea.
