doubts in part 1

[jimmyhere]

anyone knows the answers to the 5th and the 7th questions...........???

4. soft tissue protection
5. none of the above
these r the guiding cusps which protest the adjacent tissues from damage[max facial -the cheeks and the mand lingual the tongue]

2. maxillary third molar
3. mandibular first molar
4. mandibular first premolar
ans-3[it is the Y5 dental pattern for 5 cuped teeth so 1st molar]

b. Maxillary second premolar
c. Maxillary first molar
d. Madibular canine
e. Mandibular second premolar

1. a and d
2. b and c
3. b and d


4. c and e
5. d and e

3. By their arrangement and design allow room for the powerful masseter muscle. ANS: 3
4. Curve inward more sharply from the medical plance on the buccal than to do the mandibular molars.
[this one i still dont get it]

1. Rest
2. Edge-to-edge
3.Retruded contact
4.Maximum protrusive
5. Maximum intercuspal
ans-3or centric relation [CR-from this position the condyles open&close without translation and hinge axis movement is movement without translation]

7.When viewed occlusualy, the aveoli of which of the following groups of teeth tend to be aligned nearest to a straight line?
1. Right and left maxilary central and lateral incisors
2. Right and left mandibular central and alteral incisors

4.All amxillary first premolars and first molars
5.All mandibular anterior teeth.
ans-2[why no idea]

8.Which of the following is NOT normally an alterable factor in the articulation of teeth?
1. incisal guidance

b. On the lingual, it is more incisal than on the facial
c. On the mesial, it is more apical than on the distal
d. on the facial, it is more apical than on the lingual
e. On the facial and the lingual, it is at the same level

ans-1[i guess becoz distally there is a deep concavity just above the cervical line in LI ][/QUOTE]

AS A RULE, THE GREATEST CURVATURE OF THE CERVICAL LINE IS ON THE MESIAL SURFACE N GREATEST CEJ CURVATURE OF ALL THE TEETH IS ON THE MESIAL SURFACE OF MAXILLARY CI AND THE FACIAL N LINGUAL CERVICAL LINE CURVE TOWARD THE APEX EQUALLY EXCEPT FOR MAND. CI N LI WHERE THE LINGUAL CURVATURE IS GREATER

so the distal curvature of not just LI but any teeth has to be apical than mesial except for max. CI of course.

I think you are correct. I did some research over the net and I could not find anything about relation between Gartner syndrome and increased suspectability to infection.
However, if it is HYPOpituitarism that could cause Addison disease (low ACTH hormone production) and one of the complications of Addison disease is the Addison Crisis which is could be caused by an infection as FLU.
Let me know if I,m wrong. 😎 😎

i think u are right answer has to be hypopitutarism

[anjali 1]

injury to the spinalcord at which level will damage the spinal cord?

 

[Toshiba]

the action potential initiated at the mid point along the length of the nerve terminal will travel
a.toward the nerve ending
b.toward both the soma and the nerve ending .

I think the answer is b. cos i think I read it in a pilot exam.
But I even think the answer could be a.
Does anybody know the right ans.

a. stromal connective tissue
b. cells of the surface of the epithelium

if the anticodon on transfer-RNA is 5'ACG3', then which of the following is its corresponding codon on messenger-RNA?

a. CGT
b. CGU
c. TGC
d. UAG
e. UGC
someone has already ans. this que. as b. in this thread

I might be wrong but guys plz reconfirm this answer.

i think toshiba u r right. amyloid is deposited extracellularly. so ans shd be . A

 

[rtvj]

the answer is b.CGU

The anticodon is seen on tRNA and codon on mRNA
ACG 5' to 3'.... u shuld actually read it as GCA..i.e 3' to 5' since it is anticodon.
the codon for this will be read as 5' to 3'...so the answer is CGU.
As a rule if a codon is not marked one shuld always read it from 5' to 3'.

hope i dint confuse u too much..If u have kaplan notes u can go through Transcription of tRNA's in mol bio chapter of biochem for more understanding.
i think this is the explanation..if someone thinks otherwise pls lemme know.

[bhumika_201]

But in 1 place it was given A as the answer and somewhere else it was C.that is why i asked which is the right answer....?

hi silvestephen
ya answer of this question is C.the LARGEST incisal/occlusal embrassure is present between maxillary lateral incisor and canine.and the WIDEST incisal/occlusal embrassure is present betwwen maxillary canine and first premolar.
hope it helps...

hi
it is abdominal aorta followed by coronary arteries, then popliteal arteries, descending thoracic aorta, internal carotid arteries and then last circle of willis.
I saw this in kaplan CVS pathology page 198.but i am not sure if any text book has different as i am just following kaplan for references.

6. Which are the following are the parts of the conducting division of the respiratory system:

1. Primary bronchus???
2. Terminal Bronchioles
3. Respiratory bronchioles?? Doesn't the first gas exchange take place here?

conducting zone just delivers air to and from the gas exchanging areas hence anatomic dead space which is traches, bronchi,bronchioles,terminal bronchioles.
respiratory brochioles are where gas exchange takes place made of alveolar sacs and ducts
again looked in kaplan
may be i am wrong correct me if i am
Thanks

Hi can u confirm whether its tip of tongue or attached gingiva..becos i thot touch receptors referred to langerhans cells located in the basal layer of the gingiva..
thanks

langerhans cell are associated with immune system acc to decks and kaplan
i just searched on internet so i dont have a book to refr it.
for touch receptors we have meisseners receptor and pacinian in subcutaeous skin

3. Respiratory bronchioles?? Doesn't the first gas exchange take place here?

conducting zone just delivers air to and from the gas exchanging areas hence anatomic dead space which is traches, bronchi,bronchioles,terminal bronchioles.
respiratory brochioles are where gas exchange takes place made of alveolar sacs and ducts
again looked in kaplan
may be i am wrong correct me if i am
Thanks

😕 How uncouplers affect P/O ratio? Increase,decrease?
Colonies with H or Y shaped filamentous m-organisms?

 

[katya]

😕 Can anyone explain this Q?
Each of following is contributes to hepatic failure exept one:
A. Asterixis-'liver flap' tremor of extemities
B. Gynecomastia-Increase in estrogen production
C.Mallory bodies-keratin inclusions in alcoholic cirrhosis
D.Spider telangectasia-alcoholic cirrhosis


So it seems to me that there is no exeptions in this case, but we have to answer somehow on exam!!!

I have seen this question before and the answer was mallory bodies. I do not think they actually contribute to hepatic failure, but are seen in the hepatocytes during alcoholic cirrhosis

P/O ratio is determined by the number of ATP's generated per O2 consumed.
Uncouplers decrease ATP synthesis and increase O2 consumption.
So, I think the P/O ratio will decrease.
pls correct if wrong.

i think the answer is mallory bodies too. it is present but i think it does not contribute.

central stimulus is by carbon dioxide and peripheral is by level of pH so choice D as that wud be the driving factor in this case

the ans is 2
the submandibular duct runs anteriorly to open by one to three orifices on a small,fleshy sublingual caruncal(papilla)on each side of the lingual frenum.
