with 9 comments

2011a(14)97b(4) Describe the physiological effects of general anaesthesia on temperature regulation

2009b(11)00b(7)98a(7) Describe the role of insulin in fat metabolism

2008b(15): Describe the changes that occur with ageing that effect O2 delivery to the tissues during moderate exercise

2008b(10): Describe sepsis and describe the metabolic consequences of sepsis.

2008a(10)/2003a(11)/1996a(6): Define thermoneutral zone. Briefly explain how the body regulates temp when the ambient temperature exceeds the termoneutral zone

2008a(9): The skin, the kidneys, and the carotid bodies are examples of where specific organ blood flow is far in excess of that organ’s metabolic requirements. For each example, explain what the physiological role of the high organ blood flow is, why this high flow is an advantage to the person and a brief description of the mechanisms involved.

2006b(16): Describe the physiological consequences of acute hypoglycaemia

2006b(14)/1996a(5): Compare and contrast the physiological effects of a 6hr fast of fluids and food with a 24hr fast in a healthy adult

2006a(13): Describe the factors that influence metabolic rate

2003a(15): Describe the physiological actions of thyroid hormones

2001b(3): Describe the fuel sources used during early and sustained fasting in man

2001a(5)/1996b(2): Explain briefly the role of the skin in maintaining a normal body temperature

1996b(8) Briefly explain how an ‘O2 debt’ arises and how the body deals with it

  1. HI Amanda,
    Seasons greetings! I have just been reading about the tyrosine kinase insulin receptor and in your answer to 2000b(7) you state that is is a GPCR. Most textbooks seem to state that the tyrosine kinase protein is activated directly by insulin. There may some down stream g-protein activity somewhere, but I don’t think this system is really a GPCR. Cheers, Graham

    • G’Day Graham! Hope Xmas & New year’s weren’t too burdened by study! Thanks again for the feedback..the appropriate changes have been made!

  2. Hi Amanda! With reference to: 2009b(11)/2000b(7)/1998a(7): Outline the actions of insulin that affect fat metabolism. The last point you made in your answer (nr 4) states an INcrease in glucose 6 phosphatase. Is this correct? Should it not be a decrease? See Kerry Brandis pg 171. Thanks! Theo.

    • Hi Theo Thanks for pointing out the typo – appropriate corrections have been made.

  3. Hi Amanda,
    Amazing site – greatly appreciated.
    Just a (pedantically small) point regarding 2001a(5)96b(2) on the skin’s role in thermoregulation…

    You have attributed incr. sweat production in raised ambient temp to increased SNS/ACh activity. It’s probably not SNS-related, as the overall impact of the hypothalamus is to DOWNregulate SNS activity when T(ambient) > T(TNZ). Looks like the sweat production is probably locally mediated (increased ACh release/sensitivity) as a direct result of higher temp. (http://jap.physiology.org/content/100/5/1692.long)

    Cheers, JP

    • Hehe…scratch that! It’s both. There IS selective upregulation of SNS activity to sweat glands, with downreg in other areas. Smart thing, that hypothalamus!! JP

  4. Hi Amanda, there was a TPN question asked in 07, asked again in Feb this year, is there an answer for it on your site somewhere I can’t see?

    cheers

    • Hi Michael

      It appears not. Perhaps someone may submit the answer for posting on the site…

  5. Hi Amanda
    Great work
    Question on calcium metabolism has 2errors
    Vit d activate osteoblasts so don’t increase resorption of bone and calcitonin inhibit osteoclasts not osteoblasts

    Thank you
    Ahmad
