Hey guys:

Thank you for your quick replies.
I still have my dout about # 125 as well as sjchand, I think it could be atria.

#173
Osmosis: transfer of a liquid solvent through a semipermeable membrane that does not allow dissolved solids (solutes) to pass. Osmosis refers only to transfer of solvent.
Not allowing dissolved solids would be the same as not allowing nonpenetrating solutes??????
I am confused now. Anybody knows this???

:eek:

answer to q 82
is [A]
coz cervical lines in permanent teeth coverge apical towards cervical line

answer to q no
97
[A]
GLINDING/SLIDING MOVEMENTS OCCUR IN UPPER JOINT CAVITY
n hinge movements occur in lower joint cavity

answer to q no 100
is wrong printed :confused:
there is no role of superior salivatory nucleus in otic ganglion
the pregangliolinc fibres in inferior salivatory nuclei goes to 9th cranial nerve through here lesser petrosal nerve n reaches the otic ganglion
from otic ganglion the post ganglionic secretomotor fibres reach the auricultemporal nerve and then parotid glands!!

hope im right ...correct where ever wrong :)

Orban clearly states that enamel rods deviate in the apical direction and they converge in their outward course while forming fissures and pits. Changing direction and converging are two diff things.

d. Hypertension.
e. Hyperkalemia.

i think this shud be E as there is sodium retention leading to increased sodium and hence loss of potassium in urine is there.
correct me if i am wrong







i think answer for 184 should be a
bec glucocorticoids cause protein breakdown not anabolism,
aldosterone cause K & H excretion but increased plasma K level stimulates more aldosterone synthesis. in cushing syndrome level of glucocorticoid /aldosteron/androgen increased.

i think ans is a
if i m wrong plz do correct me.

i checked found increased potassium but not anything about protein anabolism

Guys, I agree with Scha2005 about glinding/sliding movements occuring in the upper joint cavity, but then the answer would be B. These because the boundaries of the upper joint cavity should be disk and articular eminence. For the lower joint cavity should be condyle and disk.

Am I right?

Plez someone help me with answers and explanation. Thanx.

4. Which of the following condition causes myelin degeneration of the axis cylinders of the peripheral nerves?
a. lead poisoning.
b. silver poisoning.
c. mecury poisoning.
d. bismuth poisoning.
e. tetracycline intoxication.

A
lead causes stippling of RBC which causes damaged blood vessels.Mercury and lead can cause progressive myelin degeneration
Damaged blood vessels causes decreased oxygenation of brain white matter. Myelin cannot form. Demyelination occurs.



10.Which of the following represents the pulmonary neoplasm MOST likely to produce ACTH?
a. mesothelioma.
b. adenocarcinoma.
c. small cell carcinoma.
d. squamous cell carcinoma.
e. bronchioloalveolar carcinoma.

choice c

Small cell carcinomas arise in peribronchial locations and infiltrate the bronchial submucosa. Widespread metastases occur early in the course of the disease, with common spread to mediastinal lymph nodes, liver, bones, adrenal glands, and brain. In addition, production of a variety of peptide hormones leads to a wide range of paraneoplastic syndromes. The most common paraneoplastic syndromes are the syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and the syndrome of ectopic adrenocorticotropic hormone (ACTH) production.

if i m wrong plz do correct me.

hi
i'll go with ur choice of increase in anabolism
coz cushing sydrome is increased level of glucocoticoids /aldosterone/androgens
n the action of glucocoticoids is to increase glycolysis,glucogenolysis
i.e increase in formation of glucose so it doesnt have any anabolic effects
also as aldosterone level is increased there is more sodium retention definately
but if we see aldosterone activity depens on sodium potassium ratio any change leads to increase in activity
i think choice shd be [a]
still if nayone has nay other choice ...let us know :)

thanks

5. When a brief period of hysterical hyperventilation causes respiratory alkalosis tetany might be caused by a sudden DECREASE in which of the following kinds of calcium.
a. total Serum
b. Ionized serum
c. Citrate bound

Ans: B. A decrease in ionized calcium causes an increase in neuromuscular excitability.

6. Total urinary nitrogen excretion is LEAST when an individual is
a. starving
b. On a well balanced diet
c. On a diet containing adequate fat and carbohydrate but no protein.

If daily protein intake is relatively constant and the patient is in a steady state, then urinary nitrogen excretion is roughly equal to nitrogen intake. Therefore, using the urea nitrogen concentration in the 24-hour urine, protein intake can be estimated.
Based on this, I would say the answer is C.

Plez do correct me if wrong ;)

Thanks you guys...I really appreciate ur time ... :luck: :thumbup:

WHICH ONE OF THE FOLLOWING IS INVOLVED IN SYNTHESIS OF RIBOSOMAL
RNA?

1.NUCLEOLUS
2.MITOCHONDRIA
3.GOLGI COMPLEX.
4.ROUGH ENDOPLASMIC RETICULUM
5.SMOOTH ENDOPLASMIC RETICULUM

Answer is 1.Nucleolus..that is where rRNA and protein synthesis takes place(Kaplan)

184. Cushing's syndrome is characterized by each of the following conditions EXCEPT one. Which one is this exception>
a. Increased protein anabolism.
b. Increased androgen levels.
c. Hyperglycemia.
d. Hypertension.
e. Hyperkalemia
Its given in Harshmohan(pathology):Increased protein breakdown results in wasting and thinning of the skeletal muscles.
hypokalemia is also seen in cushings syndrome.
HYPOKALIEMIA is a symptom of Cushing's disease

Cushing's syndrome (~15% of all cases of spontaneous hyperadrenocorticism) occurs as the result of a typically benign tumor of the adrenal gland, which causes the gland to secrete excessive amounts of cortisol.

Cushing's disease (~85% of all cases of spontaneous hyperadrenocorticsm) is cased by a typically benign tumor on the pituitary gland, which in turn results in an overproduction of adrenocorticotropic hormone (ACTH), the hormone which stimulates production of corticosteroids by the adrenal gland. Cushing's disease is also commonly referred to as Pituitary-Dependent Hyperadrenocorticism (PDH).

while searching on net it was also given under cushings' syndrome, so I'm not clear abt this.

hI,
Could you plz explain how does the horizontal overlap not affect height of cusps?I thought it was intercondylar distance.
And also if the horizontal overlap is more,psterior cusp height should be less.

i think i read somwwhere increasing intercondylar distance increses the width of fossae.
do correct me if u think of more appropriate choice.thanks

increasing intercondylar distance widens the fossae.
do correct me if u think of more appropriate choice.thanks

hey guys, help please

155) From saggital plane progressing anteriorly,axial inclination of anterior teeth

a.remains vertical
b.inclines facially
c.inclines mesially
d.inclines distally
e.inclines lingually

Thanks

hI,
Could you plz explain how does the horizontal overlap not affect height of cusps?I thought it was intercondylar distance.
And also if the horizontal overlap is more,psterior cusp height should be less.

On pp. 145 of Okeson's book "Management of Temporomandibular Disorders and Occlusion," it says...

Vertical Determinants of Occlusal Morphology (cusp height and fossa depth) are: Condylar guidance, anterior guidance (vertical & horizontal overlap), plane of occlusion, curve of spee, and lateral translation of movement.

Horizontal Determinants of OcclusaL Morphology (ridge & groove direction) are: distance from rotating condyle, distance from midsagittal plane, lateral translation movement, and intercondylar distance.

So, i think the answer to the question below is intercondylar distance.

Question: Each of the following factors affects heights of cusps and depths of fossae on restorations EXCEPT one. Which one is this EXCEPTION?
A. Curve of Spee
B. Intercondylar distance
C. Vertical overlap of anterior teeth
D. Horizontal overlap of anterior teeth
E. Steepness of articular eminence

moving this thread to the dental exams and licensure forum...!
