I'm having a hard time memorizing the steps of the coagulation cascade. Is there a mnemonic or some sort of easy way people are using to memorize all the intrinsic, extrinsic, and common pathways?
I don't think there is. I think you just have to draw out a diagram over and over and try to turn it into a story. What parts of it are you specifically having trouble remembering, I mean are you having trouble remembering what activates what or which require calcium or what?
Yes, I am having trouble remembering what activates what, but also having some trouble remembering what each factor is. For example, Factor I = Fibrinogen, Facter II = Prothrombin, Factor III = Tissue Thromboplastin, etc. And another thing, some texts have simpified steps of the extrinsic, intrinsic, and common pathways. While other texts are more comprehensive. So, it's a bit confusing getting it all straight.
A couple of specific questions.
1) Both the intrinsic & extrinsic pathway are occuring at the same time correct? For example, a trauma such as a paper cut would set off both pathways simultaneously, right?
2) Is the coagulation cascade (ie intrisic, extrinsic, common pathways) a part of primary hemostasis or secondary hemostasis?
1) Yes, they both occur at the same time. However, the designations of "intrinsic" and "extrinsic" pathway are only really useful in a laboratory setting (i.e., determining PTT or PT). In vivo, the two pathways likely interact with each other extensively (for example, 7 can activate 10).
2) Secondary hemostasis. Primary hemostasis refers to the formation of the platelet plug
One thing I use is this mnemonic: picturing a woman crying over a break up, talking about her ex (extrinsic pathway), and how he was a professional hockey player (the number 7 turned upside down looks like a hockey stick). The whole time she is crying, so she is using a tissue (factor). But before her boyfriend played hockey, he also played baseball (10 looks like a bat and a baseball) and golf (9 looks like a golf club).
how does heparin work? anyone have a succint answer for that? I know that it works in the intrinsic pathway (measured by PTT) and it works with AntiThrombin III to inactivated Factor 5 and 8?

These are notes from our board review that I've attached. So, it might be a little hard to understand. But, we sat there in review and drew it out a few times and everyone in my class pretty much mastered it. Hope you understand the notes.

simplify by ditching the roman numerals, and using alphanumerics instead
12? no, 11.98. i'm intrinsically a cheapskate...
the rest should be bruteforceable.

OMG dont even try to MEMORIZE this, because you ll have further problems with drugsI'm having a hard time memorizing the steps of the coagulation cascade. Is there a mnemonic or some sort of easy way people are using to memorize all the intrinsic, extrinsic, and common pathways?
Top kek, who tells you to learn that way? Is it even helpful?One thing I use is this mnemonic: picturing a woman crying over a break up, talking about her ex (extrinsic pathway), and how he was a professional hockey player (the number 7 turned upside down looks like a hockey stick).

It is helpful for someone who had series of breakups with hockey, baseball and golf players.Is it even helpful?
