The distal inclination in roots of the permanent mandibular first molar is:
A. http://forums.studentdoctor.net/c:%5CReena%5CKap%5C1%5C15_files%5Citem_files%5Cspacer%281%29.gif more pronounced in either root, depending on the tooth
B.
usually more pronounced in the mesial root
C.
usually more pronounced in the distal root
D.
usually equal in both roots
The correct answer is B. In the mandibular first molar, one of the major distinctions between roots is the greater distal curvature of the mesial root. The distal root, by contrast, is usually more straight, without significant curvature. Another distinction is the deep root concavity seen running the length of the mesial surface of the mesial root. The distal root, by comparison, will have no similar concavity or a very slight depression. This concavity will sometimes express itself as a partial split (bifurcation) of some small section of the apical end of the mesial root into two roots. This feature is rare to unknown on the distal root.

i saw this q in kaplan q bank. their answer was A...round. i rmember it because i picked 'oval, w/ slightly wider labial surface'...that was wrong.
q ] the clearance of several substances was measured at constant GFR n constant Urine flow rate , but increasing plasma conc of the substance .under these conditions , clearance will increase at high plama concentrations for which of the foll substances ?
creatinine
mannitol
penicillin
phosphate
urea

[what on earth does this mean]... plzz explain m
answer is phosphate.
it means that if levels in body are too high (more than what is needed) , more levels will be seen in urine.

could please tell me why its not creatine.I truely appreciate your reply.thanks
1.antivirals act against

2. mouth when opened widely, condyles r postioned
in the anterior glenoid fossa
in the posterior glenoid fossa
either inferior to the articular tubercle or anterior to it
nucleic acid
proteins

well, i think its because creatine is produced at a constant rate ( that is why its used as a reliable source for measuring GFR), there is not much fluctuation in its levels. whereas phosphate increases/decreases in diseases such as hyperparathyroidism.
that is my thinking, anybody is welcome to add.

1- proteins (think DNA polymerase etc...they are enzymes= proteins)
2- anterior glenoid fossa

there goes my bubble....shuntyman just burst it =( *no more being shuntyman for me*
anyways, but if condyle goes anterior to anterior tubercle wont that cause 'lockjaw'?

highest osmolality is present in [which part of nephron]
collapsed trachea is known as ??

collapsed trachea- tracheomalacia

due to flaccidity of tracheal rings.
2- agree w/ dreamdental....
so the Distal tubule will hv more osmolality compared 2 ascending n descending limb of loop of henle.
osmolarity increases as it goes down the descending limb and decreases as it goes upwards.DCT will have less osmolarity compared to descending and ascending LOH

it would be called anterior dislocation in that case.
from what i remember when jaw is wide open condylar head glides to the level of ant tubercle and past it if patient has habitual dislocation so i would agree with shuntyman.
ohhh..right....got it.....thanks guys!
hey thanks
dont mention it !we are in the same boat.

hey . porcelain258 . acc to our discussion .. why not its "C" as . Cyclic AMP-- activates protein kinase A, which subsequently activate lipases found in adipose tissue.
Which of the following features is common to both mandibular first and second premolars?
a. Triangular in outline occulssal table
b. Horizontal distal marginal ridge
c. Bilateral symmetrical crown
d. Dissimilar marginal ridges
e. No transverse ridge
for this i think it should be B .. isnt ??? i dn knw ans for all these ..a s u cn see in mand 1st there is no or little mesial marginal ridge .. n for both distal is horizontal.
