[uabsfm]

endogenous cholesterol is cholestrol the body makes in liver.
This get convereted in cholestrol esters,bile &salts and use to make steroids over here i think most appropriate answer is steroid.

I think ans should be cholic acid as bile acids are required and produced more in the body then steroids thats my logic I am not sure about the ans any clue?

 

[uabsfm]

saccharolytic

hey Topiaz are you sure about the ans sacchrolytic and bacillus for the filamentous form?

can you exlplain me why it is sacchrolytic?

thanx for the answer

 

[uabsfm]

correct me if i am wrong

if V nerve is cut below medulla wat happens

a loss of sensation of pain same side
b loss of sensation of pain ipsilateral
c loss of propriocepion same side
d loss of sensation of propriception opposite side


I think that should be the ans as loss of pain sensation is opposite side to the side of lesion
correct me if wrong

 

[toothfairy482]

UABSFM, can you please explain this ?

also other situations if nerve cut above medulla etc etc...

or where is a good place to read about it?

 

[topaiz]

if V nerve is cut below medulla wat happens

a loss of sensation of pain same side
b loss of sensation of pain ipsilateral
c loss of propriocepion same side
d loss of sensation of propriception opposite side


I think that should be the ans as loss of pain sensation is opposite side to the side of lesion
correct me if wrong

sensory sensation loss is of the ipsilateral side and motor sensation is lost of the same side.........correct me if i am wrong.

 

[vibhakar]

patient with mandible moves its mandible to right side.
which side is affected?

 

[uabsfm]

sensory sensation loss is of the ipsilateral side and motor sensation is lost of the same side.........correct me if i am wrong.

the meaning of ipsilateral is the same side, I think you are consedering the ipsilateral as contralateral i mean opposite side

 

[uabsfm]

diabetes mellitus is an autoimmmune or degenerative dz?

 

[uabsfm]

UABSFM, can you please explain this ?

also other situations if nerve cut above medulla etc etc...

or where is a good place to read about it?

if nerve cut above the medulla then it will produce loss of sensation on the opposite side as the pathway crosses in the medulla...........

you can read this from any cns textbook

 

[topaiz]

the meaning of ipsilateral is the same side, I think you are consedering the ipsilateral as contralateral i mean opposite side

Ya you are right THANKS.

also plz look into my above posted q too
it came in exam

 

[vibhakar]

cell bodies present in sensory afferent sympathetic abdominal viscera?

 

[DAT-Scared]

diabetes mellitus is an autoimmmune or degenerative dz?

hey I think type one is hereditary and type II is autoimmune or environmental.

what I know is that the primary herpetic infections are usually subclinical and when they recurr they do most commonly on the labial mucosa, so I am not sure about the answer 😕

 

[dmn]

thanks a lot for the help!!!

 

[dentluv]

diabetes mellitus is an autoimmmune or degenerative dz?

Diabetes mellitus Type 1 is an autoimmune disease

 

[dentistus]

patient with mandible moves its mandible to right side.
which side is affected?

right side affected

1. ulcers of recurrent herpes occur on mastication mucosa. herpatic ulcers could occur in which
a. buccal mucosa
b. labial mucosa
c. hard palatal mucosa[ans]
d. mucose of soft palate
e. floor of the mouth
not vry sure

oral manifestation of primary herpetic lesions are gingivostomatitis. it can occur anywhere in oral cavity but more commonly it starts from the anterior portion of the mouth. so ans should be LABIAL MUCOSA.
in case of recurrence the lesions are more localised n less severe..and are seen commonly in keratinized mucosa i.e hard palate and attached gingiva (orally).

when mandible is moving towards the right side, what is direction of mandibular working side teeth?
and what is direction of MAXILLARY working side teeth?
also, if mandible moves towards right, what is overall direction of mandible on working side?
mesiolateral or distolateral?

mesial n distal pulp horns r not present in mand. canine

 

[vibhakar]

when mandible is moving to right..
for mandible working movement to right
for maxillary left as it will move opposite to mandible

 

[dentluv]

Maxillary 1st premolar has 2 roots,Buccal & Lingual
But Max 2nd premolar has only 1 root

@dmn
can u plz explain premolar qs
max ist n 2nd pm both have two roots?
isnt it
plz explain


explain bennet movement ans too

Bennett movement:
The working side (rotating) condyle has a lateral side shift of translation during the earliest stage of lateral movement.

The condyle on the working side rotates about a moveable
vertical axis.
The non-working condyle moves downward, forward and
medially

Maxillary 1pm
-two roots (buccal-lingual)
-Lingual cusp tip to mesial
-Mesial marginal groove
-Mesial concavity
-distal curve to the buccal root
-buccal cusp-mesial cusp ridge longer than distal

Maxillary 2pm
-One root
-buccal cusp-the mesial ridge shorter than the distal
slightly.
-lingual cusp tip to the mesial
-shallow root concavity on mesial
-crown more rounded than the 1pm occlusal view.

hope it helps!!

and what is direction of MAXILLARY working side teeth?
also, if mandible moves towards right, what is overall direction of mandible on working side?
mesiolateral or distolateral?

On the working side, The mesiolingual cusp of the maxillary 1st molar tracks over the lingual groove of the mandibular 1st molar.
the lower distobuccal cusp tracks under the upper buccal groove.

on the non-working side, the mesiolingual cusp of the max 1st molar tracks over the lower distobuccal groove. the pathway is in a distobuccal direction.
The lower distobuccal cusp tracks in a mesiolingual direction.
