2004 Pilot - Omohyoid Question

[DrTacoElf]

---

Members do not see this ad.

#11 asks each of the following muscles usually appears in the floor of the posterior triangle except one. Which is the exception.

sternohyoid (answer)
medius scalene
splenius capitis
levator scapulae
anterior belly of omohyoid (i'm assuming this means the superior belly and the last time I checked it was no where near the floor of the posterior triangle. I suppose if it said posterior belly of omoyoid I could agree with it but what the heck is going on here???)

 

[ObliqueRidge]

I think they meant to say posterior belly of the omohyoid..but, either way the only logical answer would be sternohyoid b.c. that is nowhere close

Yeah it has to be a mistake I just wanted to verify 🙂

so they made a mistake in one of the 2004 exams?? will it get thrown out? can the test takers who took it in 2004 report it?

i swear to god, i saw a question on some old exam that went liek this:

pt's lab results show decreased factor 8, what dz does he have?
A) christmas dz
B) hemophilia B
C) von willy's
D) HIV-related pancytopenia

can somebody plsssss~ explain😕😕😕😕

C- Von Willy's. It has something to do with factor 8 being associated with Von Willebrand factor. So if you have a deficiency in one, then you'll have a deficiency of the other. Not sure if it's correct...but that's what I would guess.

Christmas disease and Hemophilia B are a lack of Factor 9, and HIV-related pancytopenia is just something that doesn't sound familiar.

hi here is the ques
The absorption calcium from the small intestine is increased by
1. the ingestion of fat
2. a high phosphate intake
3. the administration of vit A
4. lowering the pH in the intestine
5. the administration of parathyroid hormone

in ans key it is 4
i dont agree with the ans i think the best ans is 5 because with increase parathyroid there is increase in absorption of cal in small intestine in presence of vit D.
if im wrong anybody correct this.
thanx

i would go with 5 too. I don't see how lowering the pH would increase Ca absorption. The only way I can see 4 being the answer is maybe something to do with the carotid body detecting a change in pH and trying to increase the blood pressure by absorbing calcium...maybe???

There wa a discussion on this before. I too agree that PTH is a better answer. Someone found information that stated the way in which calcium is absorbed (divalent cation) is promoted by a more acidic enviroment so technically it would increase absorption but PTH is a way better answer.

hi ,
the naturally occuring fruit sugar D-fructose has a specific rotation of -88.5 degree.it is a D sugar inspite of negative rotation because of its
1. similarly to D glucose
2. occurance in natural products
3. presence in sucrose,a dextro sugar
4. stuctural relationship to d-glyceraldehyde
5. utilization by organisims which require sugars with D configuration.
in ans key it is #4.
can anybody explain this for me how is the ans is 4.

D and L designations are based on the configuration about the single asymmetric carbon in glyceraldehyde. When you have a sugar with more than one chiral center, you base it on the asymmetric carbon farthest from the aldehyde or keto group. You compare the configuration of that carbon to d- or l-glyceraldehyde to determine nomenclature.

thankyou so much🙂
