Comment of the Week
After the cuff is tied, the cells and tissue distal to the cuff will continue consuming ATP (
ATP->ADP), but no fresh blood will be delivered to “clear” what will be an accumulating amount of ADP and other metabolites. ADP (=Adenosine) is itself a proxy of consumption and drives vasodilation of arteries! (Evolution is smart!) Increasing ADP/Adenosine in a “local environment” is a signal to the body that a lot of consumption is occurring there; thus, arteries and arterioles naturally dilate to increase blood flow rates and “sweep away” metabolic byproducts.
Lol of the Week
Which of the following reasons is why this question is bull?
1) Using the word "cyclic" instead of tricyclic for clarity
2) Knowing all of epidemiology of all drugs
3) having to reason out that anticholinergic effects are probably the worst over alpha1 or H1 effects to no certainty.
4) The crippling depression of studying for days-to-weeks on end to probably do average on the test.

This is a cohort study! (Since it involves splitting people into "groups"; group = cohort.) But the stem asks what "best describes" the design. So, yes, it's a cohort study but a more precise ("more specific") description is Open-label. In other words, "Open-label clinical trial" is a type of cohort study, and, in this case, "Open-label" is a more precise description of what is described in the stem.
Not sure looks like it might be free ribosomes or other such small cytosolic structure (I picked E too, thought B looked way too big!)
same here!! marked e thinking of it as a mitochondria
Hi Lauri, this is normal. We can't post the whole question due to copy right laws but you can almost always find the question you are looking for and the answer to by going to the form and then Ctrl + find -ing the age of the patient and other key words or the answer!
HI LAURI. THANK YOU FOR DEMONSTRATING YOUR PROFICIENCY WITH ALL-CAP COMPOSITION!
The correct answer was atrioventricular BUNDLE-- it's also known as the Bundle of His. AV Bundle ≠ AV Node.
Now it's more confusing to me:) because av bundle is more inferior to the av node.
Patient has ASD --> need to repair interatrial septum. AV bundle aka bundle of His is located neart interatrial septum. Coronary sinus opens into atria but is not located near the interatrial septum
ASD has typically 3 associated sounds according to UW, they are all about increased blood in RA. Increased blood in RA causes more blood do ejected from tricuspid (dşastolic rumble), and more blood to be ejected to pulmonary circulation which cause pulmonary flow murmur (midsystolic murmur in pulmonary region). It even can cause pulmonary regurgitaion like murmur, but most important murmur in ASD is typically midsystolic murmur. You can check it out on FA 2018 page 284
Ok, what I learned: Extra blood in the right heart (due to ASD) doesn't lead to pulmonic stenosis? Instead, it's that pulmonic stenosis = most common comorbid heart association with ASD
No it's not pulmonic stenosis, it doesn't lead. Murmur associated with ASD is pulmonic stenosis-like murmur, because it's caused by excess RA and RV volume ejecting to the pulmonary arteries. So it's same location with pulmonic stenosis, and it's systolic. You get it?
I believe it's that this muscle everts the foot + runs over the lateral malleolus
.. But the phrasing on the question is odd
