am4140  @monkey - with real anorexia, she wouldn’t necessarily have boobs either. If she’s got boobs she has the nutrition to develop boobs. That was my thought. +
freckles  the patient is actually what ever gender they want to identify as. If this was a 5 alpha reductase deficiency the patient would have experienced masculinization of external genitalia during puberty when testosterone levels increase significantly.

jurrutia  GPiib/iiia receptor is not inhibited by aspirin. Aspirin prevents the upregulation of GPiib/iiia which is not the same as inhibiting the receptor itself. +1
jj375  @jurrutia I think you are thinking of Clopidogrel, prasugrel, and ticlopidine which downregulate GP2b3a expression. Aspirin inhibits COX therefore inhibiting TXA2 and platelet aggregation. +

regularstudent  Isn't the brush border still part of the intestinal lumen? Don't the amino acids enter into the intestinal cell (the "intestinal mucosa")? +1
drdoom  @regularstudent No, the lumen is literally the cavityβ€”the empty space. +2

sympathetikey  Exactly. I knew it had to due with fusion of the neuropores but had never heard of sclerotomes. Thanks for the explanation. +17
hungrybox  Fuck I picked "Formation of neural tube" but yea that makes sense... that would affect the whole CNS +5
ruready4this  I also never heard of sclerotomes and I chose that and then switched it to formation of the neural tube because I thought that was close enough ugh close enough is not the right answer +2
ih8payingfordis  FA 2019 Pg 479. They don't specifically mention sclerotomes but you can review the different neural tube defects here :) +
failingnbme  everyone who selected neural tube is basically me :P +
an1  I knew it was fusion, but didn't know what sclerotomes were. so I went for the option with neural tube in it... FML. +

atstillisafraud  Thanks for a good answer. This question made me feel like I was taking T21 pills +18
medguru2295  Thank you- I was really thinking this question had 2 correct answers... of course my dumbass picked Mast cells. +5
ajss  where do i find this info?? +
paperbackwriter  @ajss pg 112 of first aid 2019, under type I hypersensitivity. Immediate --> mast cells releasing histamine and tryptase, late--> eosinophils and leukotrienes recruited via chemokines +3
graciewacie9  Wow, i missed the fact that the question is asking for the RESULT of the reaction, NOT the cause of the reaction. Mast cells cause the initial reaction, eosinophils would be the result of the eosinophils. *facepalm +9
greentea733  @graciewacie9 SAME UGH +
lba9587  Pathophys (as far as I understand it)...Mast cell degranulates, thus the phospholipid bilayer et. Al are left behind and needs to be degraded. Who comes in? Our good friend eosinophils, as they contain Major Basic Protein (responsible from breakdown of expired mast cell). Note, you can tie this in to the delayed Leukotriene effects of an allergic rxn, as the bilayer is also broken down by arach. Acid. (See this link to support my credibility https://images.app.goo.gl/3cUF3ZVc7qy8uxAi9) +
