deck, i agree with ibeflossin explanation too. it is used synonymously.

I have question on TMJ, on deck anatomy p63, it said the post. slope of eminence is covered with fibrous connective tissue, does that mean ant cover with fibrocartilage? I thought the one part cover with fibrocartilage is articular surface of glenoid fossa and condyle and disc....am I on the right????😕😕😕

Thank u guys!!!!

 

[teethie]

first of all ,thank u for bringing this doubt here.

the answer for your doubt is: hydrolysis of ATP can start muscle contraction process not creatin phosphate because atp is high energy than anything.
pool of crEatine phosphate is higher but it does not make it high energy than ATP just BECAUSE OF ITS high pool. it is only acting as a pool to rebuild high energy ATP. and from there onwards ATP hydrolysis is used by muscle.

Which following can immediately source of energy for muscle reaction?
1) creatine phosphate +ADP--> ATP+creatine
2)ATP-->ADP + phosphate...ans

but on deck bio chem p 34, it said creatine phosphate can derive its higher energy phosphate from ATP and donare the phosphate back to ADP to form ATP. The pool of creatine in fiber is about 10 times larger than that of ATP and thus serves as modest reservoir of ATP....why answer is not 1

My exam is coming less than 10 days.........plz help me ><

100% agree👍
Muscle contraction------->ATP hydrolysis to ADP
replenishment of ADP to ATP-------> Creatine phosphate

[elmos]

velocity of nerve impulse conduction in snsory neuron is related to:
presence of myelin sheath
cross-sectional area of the axon ans
why it's not myelin can anyone explain pls?

 

[ibeflossin]

velocity of nerve impulse conduction in snsory neuron is related to:
presence of myelin sheath
cross-sectional area of the axon ans
why it's not myelin can anyone explain pls?

technically you're right because conduction velocity depends on both diameter of the nerve fiber as well as presence of myelin sheath. however i believe that if you increase the diameter, you DEcrease the resistance to flow, thus increase the velocity directly and this is a measure that you can do in both myelinated and unmyelinated nerve fibers, so it has a greater effect on velocity.

 

[elmos]

thks a lot for the answer.

 

[teethie]

hi elmos,
pl read this one.
Conduction Velocity:

• impulses typically travel along neurons at a speed of anywhere from 1 to 120 meters per second
• the speed of conduction can be influenced by:
  • the diameter of a fiber
  • the presence or absence of myelin
• Neurons with myelin (or myelinated neurons) conduct impulses much faster than those without myelin.

thks a lot for the answer.

can you plz explain how increasing diameter will cause increase in resistance to flow coz i thought increasing diameter will decrease the resistance.i'm little confused with ur explantion.

 

[ibeflossin]

sorry typo... DECREASE resistance to flow.

 

[pb2007]

sorry typo... DECREASE resistance to flow.

thnks for clearing up the confusion.

 

[bratdoc]

thnks for clearing up the confusion.

Just to add if there are both options of diameter and myelin... the PRIORITY is ALWAYS the DIameter!!!.. Diameter ALWAYS comes first in importance before myelin in the answer!!!

 

[IMFdoc]

can anyone please explain me this?
"only the alpha motor neurons are stimulated monosynaptically by afferents from muscle spindles and other descending fibers"
dis is from spinal cord regulation of skeletal muscle activity.

 

[deck]

On the tooth, are both enamel rods and dentin increase density toward the coronal?????? Or only enamel??


2) On the first aid, it said germ layer is completed well defined on bell stage, but I remember deck said cap stage. Which one is right???

Thank u so much!!😍

Hey guys could not understand the answer to this question


Which of the following will most likely be INCREASED in a pateint with Hyperparathyroidism?
a.Intestinal Calcium absorption
b.Intestinal organic Phosphate absorption
c.Renal Calcitriol production
d.Renal Calcium excretion
e.Renal organic Phosphate excretion

(this is Q.363 from L-Pilot exam)

d.Renal Calcium excretion
e.Renal organic Phosphate excretion

(this is Q.363 from L-Pilot exam)

i think the answer is D. there is hypercalcemia associated w/ hyperparathyroidism, which most likely would lead to an increase in calcium excretion (since the body doesn't need to "save" as much calcium through the kidneys). also remember there is metastatic calcifications that are associated with primary hyperparathyroidism. metastatic calcifications are the deposition of calcium salts in previously undamaged tissues due to excess blood calcium that occurs particularly in hyperparathyroism & hypervitaminosis D.

can anyone explain the significance of woven bone? i am trying to tutor someone, and he keeps asking about woven bone, but i don't know the significance other than during endochondral ossification as it being immature bone that later gets resorbed. is there another significant thing about woven bone i should know before i try explaining this to him? thank you!

also if anyone has a very very simple list for all the spinal cord tracts & their functions, that would be helpful as well. he just wants "the basics" and i don't explain it in a simple enough fashion for him. thanks for the help! i really appreciate it.

P.S. if you all have any GENERAL questions about the NBDE or what the testing process was like, feel free to ask. i took it a couple months back and did very well on it (a lot better than i ever expected). however, do NOT ask about specific questions or anything like that because I WILL NOT TELL YOU as it is unethical & against my morals. i'm here to help if you have any questions about concepts or while you are studying!!

I am done with my part 1 exam. want to contribute some my experience in the exam as many of u helped me in solving the Qs.

I dont say the exam is tough, it is not easy though.All i can say it was "TRICKY".When i saw the Question,i thought its going to be easy but when i looked at the answers i was confused. u need to have a very thorough concept of what u are reading. Regarding the testlets, they are easy when u are able to diagnose the case well. otherthan that i didnt find any difficulty with those.Time is enough to solve all the Qs nd can go thru those u marked in doubt.

Sources i used:
First Aid full except Dental anatomy. For DA i used wheelers, okeson, Dental Board Busters. Biochem full kaplan review book nd 1st aid. for pathology, physio nd anatomy few topics from kaplan review. for micro complete kaplan review nd 1st aid. ASDA papers, Lot of WIKing nd Decks (Read decks compltely for 3 times.During the last revision 1 week before the exam i read decks which were not covered in my primary source like kaplan or 1st aid.Dont read the decks as it is going to be waste of time nd u cannot cover some vague topics) Rely on one primary source whether it can be kaplan or 1st aid or BRS.Try to make a strong foundation with that source.For certain topics which were not covered in ur primary source(this u will come to know when u are doing the Qs)u need to use additional books or wiki.but dont study a single topic from different books. because when ur exam is getting near u dont have time to revise all those. Make sure whether u are perfect with one concept.If u are, move on to next. If u are not, refer other sources. At the same time dont rely on a single book.

2 Days before my exam:
Brushing thru every topic nd my notes. I wish i would have time to revise DA in board busters which is very good.

Sources helped me in my exam:
First Aid cover to cover, wheelers, Board Busters for DA,doing Qs daily. dont try to memorize the answers but try to know about the other options too. that gives u a very good knowledge.

Based on my experience i want to suggest you guys to do as many Qs as u can.Plan to do atleast 100-200 Qs daily along with the concept on what the Q is about.

Try to learn with mnemonics. It doesnt count how much we studied but what counts is how much we remembered.

i thank teethie, pb2007, bratdoc nd all others who helped me.

If anyone need any help (otherthan remembered Qs) regarding ur preparation, i can help you.waiting for my score to come. lets see what god has decided for me.
GOOD LUCK guys.

thanks for all of you , bratdoc i had the same doubt for this question, and i found because you have elevated calcium in the blood you'll have elevated excretion. but i couldn't know why it's not calcitriol.

drdds3, I am so thankful to you that you shared your experience. I only did a little part to help you, your score will be basically your own hard work which you have put in already, and your honesty with this forum that despite of done with your exam, you bothered to get back to share your experience. Hope you get very good scores. I wish you all the best for your scores and admission in dental school 👍👍
Atleast this way by sharing experience, we get some relief from anxiety of the exam.

Thank you Ibeflossin for answering!! but my doubt still remains!
I agree that there will be increased renal calcium excretion due to hypercalcemia but why cant the following options also be correct?

a.Intestinal Calcium absorption

e.Renal organic Phosphate excretion

 

[drdds3]

I got some from released papers. not directly but if u know the rest of the options u can answer well in the exam

thks for your feed back, but did you have questions from released paper?

 

[teethie]

bratdoc, i totally agree with you that the other options are not wrong too. I think these kind of questions make the exam tricky. there is no way to rule ut these options because these are not wrong. i will go with choice 1 increased Intestinal Calcium absorption if I do not know the asda answer. but since i know it, i will cram it.😉

need help with this ques

if type a blood is accidently transfused into a type b recipient ,the immediate hemolytic reaction would be the result of which of following
..igM against A antigen...answer
..igA against the A antigen
..igG against the b antigen
need to confirm if i'm puttin rite logic to this , is choice one is the answer coz igM is the first one to appear wen any infection or foriegn particle comes n later igG takes over or igM has some special for blood groups .
......does anyone have idea how the alpha and beta subunits if na/k atpase are significant .i looked into wikipedia for n/k pump the diagram shows it but didnt say its importance .digitoxin works on the alpha subunits .

another doubt ,is AV NODE IS THE MAIN CONTROL for the heart rate coz digitoxin affects that n increases the rate .

IgM against A antigen is the answer for two reasons ithink:
1. that you mentioned coz IgM is the primary response
2. IgM is the immunoglobulin found on the surface of the RBCs, hence the transfusion reaction... IgG is secreted by Plasma cells


And as for your second doubt SA node is the main impulse generating node of the heart and not AV node... AV node is slower though... and Digoxin(more potent than Digitoxin) works by slowing the conductance from AV nodes... that is all i know... i dont know about Alpha Beta unit of Na/K... so if someone could elaborate that would be great..
Do correct me if i am wrong

Testlet H
A patient with hepatitis C is scheduled for extraction of posterior teeth in the right lower quadrant due to advanced periodontal disease. Tooth #28 is abscessed and draining into medial soft tissue. Tooth #30 shows a large carious lesion and is painful.
If the patient and dentist elect to extract Tooth #30, sectioning of the tooth will be required. The dentist should be aware of which of the following furcations on this tooth?

1. One
2. Two — mesial and distal
3. Two — facial and lingual...but it dosnot said section on which direction instead the furcation of the tooth...I thought # 30 furcate at M-D direction😕
   

Could anyone help me....my exam is coming less than 96 hours >< OMG

Tooth #30 the right mandibular first molar has ROOTS located MESIALLY and DISTALLY...... the sectioning of the tooth is done where the furcation is located... u also mentioned in your post that you know that the section will be facially and lingually so the furcation also has the same location i.e. FACIAL and LINGUAL
(Will u see the complete furcation when viewing the tooth mesially or distally?? No.... But U will see the furcation when viewing facially and lingually! right? hence the answer)

The membrane potential is created and sustained by ion flux. Simply speaking, any potential change is due to the ion flux.

From dental decks testlets
