7)EKG with P-waves in ST segment indicates ectopic beats in?(EXPLAIN PL)
Atria, AV node, upper bundle of HIS ,lower bundle of HIS.
answer)atria( p waves i.e atrial depolarisation in ST segment which is isoelectric period of entire ventricle depolarisation.....hence ectopic beats in atria during isoelectric depolarisation of entire ventricle)

8)Person with long history of anabolic steriod use has stopped it, which of the foll character is he likely to exhibit?(EXPLAIN PL)
Sterility, low FSH, low Testosterone, low no of Spermatids.
answer)low FSH...(i choose this simple based on exception like streility,testostrone, low spematids are related to each other ..only low FSH is odd one...if anybody has a proper explanation can please explain)

answer)venous blood

11)slight detachment of retina--->decrease of lenght from optic center,and the person exhibits?
Far sightdness, near sightness, strabismus, nystagmus.
answer)farsightened ness( coz i think decrease in lenght from optic center ll focus behind retina..which is seen in hyperopia or farsightedness)

12)blood flow to coronary A is greatest during?(EXPLAIN PL)
Early diastole , late diastol
answer)early diastole( coz that is when the pressure of heart on coronary artery is less as its the early filling stage n blood can freely flow thru coronary artery..in late diastole the chamber wud be already filled with blood and will prevent free flow of blood in the coronary arteries.

I AGREE WITH ALL THE ANSWERS EXCEPT THE ABOVE..

PERSONE WITH LONG HISTORY OF STERIOD IS EXPECTED TO HAVE LOW TESTEROSTERONE LEVELS AND SMALL TESTIS... MOST COMMN IN ATHELETES TAKING STRIOBD ON LONG TERM BASIS COZ ... OF NEGATIVE FEEDBACK MECHANISM.. HIGH STERIODS--->LOW ACTH--->LOW ADRENAL ANDROGENS-----> LOW TESTERONE PRODUCTION IN ADRENALS

thanks a lot aim high n plan

 

[god bless]

hi all
pls help me clear a few basic concepts that i'm confused

1. in decks it is stated that an increase in aminoacid cause the release of insulin and it is the insulin and not the glucagon that causes decrease in aminoacid level
also stated that increase in aminoacid especially arginine causes release of glucagon.

my doubt is if glucagon is increased on increased aminoacid level, will it not reduce aminoacid concentration.

2.it is stated that increased glucagon concentration will increase the insulin secretion.
also said that insulin is one of the factors that decrease the glucagon production
why is it like that? if glucagon causes incresed insulin secretion , will it not be viceversa also

thankyou

--insulin can effect glucagon levels...when there is increased release of glucagon ,it increases blood glucose levels---which ll inturn stimulate release of insulin ...and insulin ll decrease levels of glucagon.

please post the answer

 

[kiran87]

Thanks Aim high and morphology.I wont have confirmed answer to post.
3. The biologic effect of exotoxin A produced by Pseudomonas aeruginosa is to
c. inhibit protein synthesis---answer Because in Wikipedia its given that

P. aeruginosa uses the virulence factor exotoxin A to ADP-ribosylate eukaryotic elongation factor 2 in the host cell, much as the diphtheria toxin does. Without elongation factor 2, eukaryotic cells cannot synthesize proteins and necrose. The release of intracellular contents induces an immunologic response in immunocompetent patients.

I have seen both largest n widest being asked in question papers, yet not sure if both mean the same or the answers were wrong in the papers!!(I am not sure of the papers in which I found these, LL let u know in few days)

Can anyone explain me this:

1)If the mandibular canine on the right side is lost ,how it can effect the protusive contact on the left canine?-I would choose the answer from the options provided!!

2)Patient get a full denture and comes back after some time with the burning sensation in the lower anterior region what could be the reason for that burning sensation?- May be due to over extension or rough labial flanges

3)MI with pulmonary congestion?what could be the reason for this defect?- Left heart failure(due to ischemia,obviously) and resulting pulmonary congestion.

4Iin which bacterial infection only human beings are the carriers?- C.burnetti

5)what defects the fetus will have if a woman with 9 week pregnancy has a trauma?-

Maternal Trauma During the First Trimester
During the first trimester, the uterus is protected within the pelvic bones. Trauma during this time will either be so severe as to cause a miscarriage (spontaneous abortion or fetal death), or else it will have no effect.(info from net)​

Let me know if am wrong . By the way where is the 1st Q from?

can any 1 plz answer this question with explanation..this is from 1982 anat q.no92
--a terminal web delimits the odontoblast from odontoblastic process.this aggregation of microfilaments is found ---
1.intracellularly at basal aspect of the cell.
2.intracellularly inserting into junctional complex of the cell.
3extracellularly projecting into predentin (korff's fiber)
4.extracellularly connecting the junctional complex of the adjacent cell
5.extracellularly being continuous fibers present in cell free zone of weil.
thanks.
