Pathology question thread

[Turtle]

Since the MST 1 for Pathology (PATH20001) is coming up, I thought I'd made a thread so we can help each other prepare, and ask questions 

I'll kick it off...Can anyone explain to me the difference between Physiological and Pathological adaptation? The notes are so confusing, and she didn't explain it very well in my opinion.

Physiological adaption is your body trying to adapt to stimulus that is considered to be "normal" or unharmful. Things such as hormones which signal for you to grow may be responded to with hypertrophy.

Pathological adaptation is your body trying to adapt to a stimulus that is considered stressful or harmful. The responding to these stimulus is usually to prevent injury. For example, adapting to a high blood pressure.

Thanks so much Vea, that makes perfect sense!!

Can anyone give myself and fellow ATARnoters any hints on what was on last semesters/years 1st Path MST?
Is there anything we need to watch out for?

Also, does anyone know if old PATH20001 exams exist, or where we can get them?

This isn't exactly a question related to the content, but a question related to pathology, can someone please tell me if there are lectopia recordings for pathology?

Yes.

Can someone explain to me why the formation of transduate is non-inflammatory?
I don't get it...because it is formed during the inflammatory process? 

I know that the transduate is formed due to an increase in hydrostatic pressure in the blood vessels, which is due to vasodilation. The increase in hydrostatic pressure causes the formation of a transduate in the extravascular space.

Is it trying to say that a transduate can also be formed during non-inflammatory processes too? ie. if the volume of blood flow increased for other reasons other than inflammation

How did everyone find the MST?

The only question I spent ages on was the 2nd question about that girl cutting her arm in the motorcycle accident, and in the one about what makes successful wound healing. They were both on the last page.

Does anyone remember what they put for these questions? If you remember which ones I'm talking about :/

I put "fibroblasts and endothelial cells" for what is found in the soft pink wound, after the motorcycle accident (2nd motorcycle question).

And the one I said that was wrong, for what makes successful wound healing, was the "eliminating the cause of injury" answer.

To be honest, I thought that the midsem was pretty good. I was really worried because she isn't the best lecturer.

I put the same thing for the motorcycle accident

I don't remember the choices for the other question but I put something else.

Iwas wondering what the answer was for the monkey bar question. I said it was metaplasia but I wasn't sure. And I was confused about the activation of leukocytes question.

[Sinner]

Yep, I felt quite good about the midsem as well. Much better than biochem last sem. Here's what I put for the answers.

I think I put the same choices as well for the two questions, though for monkey bar I said Hyperplasia. Not too sure whether plasia or trophy though.

[Revi]

For the motorcycle accident question, I put answer D, due to it containing macrophages which since the initial period of inflammation was over (question said 3-7 days) the neutrophils are replaced by macrophages. Was considering picking answer A (the endothelial cells) and I'm not too sure but I spoke to some people and that's what they said, so it could be right.

The monkey bar question is definitely an example of hyperplasia. Was a little unsure of that, but Vicki Lawson mentioned it in one of the lectures.

what did you guys answer for the question relating to mechanisms leading to primary chronic inflammation? A friend and I were arguing over whether it was answer C (repetitive acute inflammation) or D (exogenous toxic agents).

Going back to the lectures seeing a couple of mistakes I've made, I don't feel too good. Anyway with primary chronic inflammation I think the question was "what isn't a cause of primary chronic inflammation" and I said it was C because the definition of primary chronic inlammation includes 'without an initial inflammatory response'

Hmm that's what I said as well, using that same reasoning that is wasn't 'primary'.

Barring that question and a couple of others that were slightly unclear, I think the mst was relatively straight forward. I was expecting the questions to be a little more in depth.

[Sinner]

The problem with the motorcycle question is that there seems to be 2 places in the CAL papers that asked about the topic yet give different answers, which seems like a bit of both.

That's why I rarely talk to people about the answers we put until I get my results. Otherwise that reduces the cap for max achievable score. Had me down for days in high school especially with math.

I'll admit it...I was one of the annoying ones at school that always wanted to talk about the SAC after we did it
