a. fibrocartilage
b. fibous connective tissue
c. synovial fluid
(periosteum or calcified bone are not in the options)

circumduction movement of arm is due to
a. axilla....................answer but not sure
b. extensor muscles
c. flexor muscles
Circumduction - The circular (or, more precisely, conical) movement of a body part, such as a ball-and-socket joint or the eye. It consists of a combination of flexion, extension, adduction, and abduction. "Windmilling" the arms or rotating the hand from the wrist are examples of circumductive movement.

b. cheek
c. lip
d. floor of mouth

5]skin

 

[teethie]

i was messed with other side ..
i agree with pb2007

1]radial--------right.
2]epitaxis-------------👍

 

[pb2007]

Is not radial a bone of medial side?

i was too confused with this but luk at the skeleton in the link .
http://en.wikipedia.org/wiki/Human_skeleton
i naswered radial coz radial is towards thumb .
this what wikipedia mentions
In anatomical position the ulna is placed at the medial side of the forearm closest to the body, parallel with the radius on both arms.
http://en.wikipedia.org/wiki/Ulna

i'm little confused with this now coz if palm faces up then radial should be outwardly placed n if we see opposite side then ulnar is lateral but wikipedia in both radial n ulnar bone supports radial as lateral .
lets see what others have to say .

 

[teethie]

pb2007 you are absolutely right👍.
i just edited my prevoius post. we should answer the question based on anatomic position only.
sorry about creating so much confusion.😳

Lining of terminal bronchiole consist of what type of epethelium?????

Pls someone reply

 

[teethie]

read this. it is ciliated respiratory epithelium which should be cuboidal. correct me if wrong.

Lining of terminal bronchiole consist of what type of epethelium?????

Pls someone reply

 

[pb2007]

Lining of terminal bronchiole consist of what type of epethelium?????

Pls someone reply

ciliated simple columnar epithelium....{kaplan }
check under respiratory anatomy chap .
it says bronchioles overall not particulary terminal so may be teethie is correct

 

[teethie]

pb2007, read this link which says it becomes cuboidal.
thats why when it branches into respiratory it is cuboidal but this transition actually starts from terminal bronchiole.


http://books.google.ca/books?id=_El...minal bronchiole columnar epithelium&f=false

ciliated simple columnar epithelium....{kaplan }
check under respiratory anatomy chap .
it says bronchioles overall not particulary terminal so may be teethie is correct

 

[drdds3]

Simple columnar. I am sure

Lining of terminal bronchiole consist of what type of epethelium?????

[drdds3]

aiming 4 dds,

are u sure the answer is synovial fluid. but synovial fluid is located on articular cartilage or bursa right ??

Few days back i searched for same question for long time but cud'n get definite clue

 

[drdds3]

Thanks pb2007. u r very helpful. when is ur exam?
can u explain why the answer is skin nd why not other options. i thought it is floor of mouth since it has a very gud blood supply
regeneration capacity is high in
a. skin......answer
b. cheek
c. lip
d. floor of mouth

[teethie]

but this question is only about terminal bronchioles. it will change from columnar to cuboidal.

for the other ques, u r right, it is mesoderm.-------------see corrected post below

Simple columnar. I am sure

hepatocytes and pancreatic acinar cells originate from
a. mesoderm --- ans --------agree👍
b. parietal mesoderm
c. visceral mesoderm

 

[pb2007]

Thanks pb2007. u r very helpful. when is ur exam?

a. skin......answer
b. cheek
c. lip
d. floor of mouth

skin is capable of mitosis so i though that' looks most appropriate .
http://en.wikipedia.org/wiki/Skin
i'm writin exm in early oct .
so wat the answer drdds3 is it skin or floor of mouth

which is not in the cell
a. centriole...............answer . [do you have answer for this drdds ]

b. lysosome
c. microtubule
d. mitochondria

 

[elmos]

teethie can you tell from you get that hepatocyte and pancreatic cell are from mesoderm i thought is from endoderm?

 

[drdds3]

even i thought it is from endoderm but not sure.
If u have any appropriate source plz provide us teethie

teethie can you tell from you get that hepatocyte and pancreatic cell are from mesoderm i thought is from endoderm?

 

[drdds3]

I dont have answers for these.
i agree with centriole.
can u look into other Qs too (pepsin and desc aorta)

skin is capable of mitosis so i though that' looks most appropriate .
http://en.wikipedia.org/wiki/Skin
i'm writin exm in early oct .
so wat the answer drdds3 is it skin or floor of mouth

which is not in the cell
a. centriole...............answer . [do you have answer for this drdds ]

b. lysosome
c. microtubule
d. mitochondria

 

[teethie]

thank u for the correction, it is endoderm not mesoderm.
but this option is not given in the question.

teethie can you tell from you get that hepatocyte and pancreatic cell are from mesoderm i thought is from endoderm?

 

[teethie]

i marked it wrong, but how cum you also answered mesoderm in your post. it was by mistake.

even i thought it is from endoderm but not sure.
If u have any appropriate source plz provide us teethie

 

[teethie]

why not water. check this link.

http://en.wikipedia.org/wiki/Small_intestine

which of the following is absorbed in jejunum except
a. water
b. fats --- ans not sure
c. proteins
d. carbs

 

[wdent]

The Answer

snake bite on arm lateral side. which bone is located?
a. radial
b. ulnar
c. humerus............Answer

Guys we should not get confused here between the arm and forearm

Here they r askin about the ARM (from shoulder ---> elbow ) ...

🙂

 

[teethie]

i was thinking radial because they said lateral side.

[bratdoc]

Thanks Teethie for the Wheeler's text👍

And yes the question says lateral side of the ARM!
so the answer is humerus
Radius and ulna are bones of the forearm!!

 

[bratdoc]

which of the following is absorbed in jejunum except
a. water -----Maybe
b. fats
c. proteins
d. carbs

Because all of these are absorbed in the jejunum.... But the proximal jejunum does not absorb Water... rest of the jejunum does!

Who ever knows the answer plz let me know!

 

[teethie]

thanks wdent and bratdoc for humerus answer.

pb2007, elmos,drdds3:
pepsin question seems weird. i never read such choices having any relation with the question. i spent too much time in looking into this question but did not get anything.
if anyone finds something pl post, or else we move on.

 

[Cindrella]

2.which of the following is deceased except one-
a.brain dna
b.mitochondria m rna
c.some cns related
I didn't understand the question 😕

3..hyoid protrusion – Geniohyoid
Options all supra and infrahyoid muscles

4.trauma at L 1 level so , which organ likely to be damaged
a.pancrease
b.kidney ......answer http://www.anaesthetist.com/anaes/patient/ans/Findex.htm
c.gall
d.liver

5. caries involves all except:
a. lactic acid
b. acetic acid
c. palmitic acid
d. oleic acid
e. linoleiic acid.............answer coz this is essential fatty acid which we need frm outside Are u sure of this pb2007 ???
plz correct if wrong

 

[Cindrella]

bratdoc, acc to wheelers:
a lobe is one of the primary sections of formation in the development of crown. Cusps and mamelons are representative of lobes. A mamelon is anyone of the three rounded protuberances found on the incisal ridges of newly eruptd incisor teeth.
There are development lines present on labial surface of max CENTRAL INCISOR (pg129 of wheelers).

on the crown of an incisor which of the following featires separates the labial lobes?
a. mamelons---this is my answer since question is about incisor which does not have development depressions. deveopment lines are different from development depressions.
b. central groove
d. lingual groove
e. facial developmental depressions--these are present on max canine.

correct me if wrong.

Hey teethie.. how can a canine have a facial developmental depression... shouldn't it be elevation ???😕

 

[drdds3]

bratdoc & teethie,

I think 'Fats' will be the answer because in kaplan review book it is given as absorption of most fat has occurred by the timechyme reaches the midjejunum
whereas water absorption occurs mainly in small intestine. jejunum and duodenum r highly permeable to water
correct me if i am wrong and confirm the correct one

which of the following is absorbed in jejunum except
a. water -----Maybe
b. fats
c. proteins
d. carbs

Because all of these are absorbed in the jejunum.... But the proximal jejunum does not absorb Water... rest of the jejunum does!

Who ever knows the answer plz let me know!

 

[drdds3]

wdent, bratdoc, teethie,

what do u think of this Q:
what is present posterior to descending aorta
a. right kidney
b. liver
c. duodenum 3rd part (ans but not sure)

 

[drdds3]

first i thought it is from mesoderm

i marked it wrong, but how cum you also answered mesoderm in your post. it was by mistake.

wdent, bratdoc, teethie,

what do u think of this Q:
what is present posterior to descending aorta

b. liver
c. duodenum 3rd part (ans but not sure)

Non of these r behind the descendin aorta ,,the answer will be choice d. IF it says non of the following !
Hope iam clear !

 

[Cindrella]

So what is behind descending aorta ??

 

[happyk9]

Cisterna chyli and vertebrate are behind the descending aorta，what else?

 

[drdds3]

Thanks wdent
wdent, bratdoc, teethie,

what about this Q:
which of the following is absorbed in jejunum except
a. water
b. fats --- ans not sure
c. proteins
d. carbs

Non of these r behind the descendin aorta ,,the answer will be choice d. IF it says non of the following !

[teethie]

AGREE with wdent.👍

hi butterfly22, read this link point mentioned under 3.D.

http://books.google.ca/books?id=9Qu...ge&q=PARTIAL PRESSURES OXYGEN TENSION&f=false

thank u teethie!👍

 

[teethie]

It is given in wheelers.
are you confusing it with something else, because there is nothing like facial development elevation present on canine. I never read it before. where did u read it from?

Hey teethie.. how can a canine have a facial developmental depression... shouldn't it be elevation ???😕

 

[pb2007]

So what is behind descending aorta ??

whereas water absorption occurs mainly in small intestine. jejunum and duodenum r highly permeable to water
correct me if i am wrong and confirm the correct one

But still fat IS infact absorbed till it reaches small intestine!! But there is NO water absorption in the Proximal duodenum!!!

Do lemme know if u find some other reference!

 

[butterfly22]

Hey teethie.. how can a canine have a facial developmental depression... shouldn't it be elevation ???😕

teethie i'm sure the answer is developmental depressions...mamelons are representations of the lobes and the are seperated by developmental depressions on ant teeth and by developmental grooves on posterior teeth.

 

[teethie]

In wheelers, it says that labial grooves are present on max central incisor also. my reference is page 95 from wheeler.

and also, we do not see any development depresions on incisor,so your point can be true for canines but question was about incisors.
does anyone want to clarify this more, please do so.

teethie datz wat i'm sayin, developmental/labial grooves seperate the lobes
and a developmental groove is defined as adepression in the crown of a tooth that marks the boundary b/w seperate lobes. so hence the answer is developmental depressions.🙂
please read dis..http://www.tpub.com/content/armymedical/MD0501/MD05010131.htm

and also see fig4-10, pg 106,Wheeler's

6. At secretory stage of uterus the ovary is in which phase
a. proliferative (ans i think)
b. luteal====ANSWER(i think Luteal phase is also known as Secretory phase)

Though this question is still not clear to me(uterus/ovary?)
