After an automobile accident , a patient's chin deviates to the left on opening mouth widely.His mandible is probably fractured at which of the following points?

a. genial tubercle
b.left condyolar neck
c.right condylar neck
d.left mental foramen
e.right mental foramen

post the correct anwer and justify it with right explanation

 

[wise146]

left condylar neck is where accident occurred. The intact right condylar neck with attacked superior lateral pterygoid muscle will move chin and mandible to left side--please let me know if i am wrong

 

[Typo]

left condylar neck is where accident occurred. The intact right condylar neck with attacked superior lateral pterygoid muscle will move chin and mandible to left side--please let me know if i am wrong

Exactly - this question is just a twist on the whole "which muscle performs left lateral excursion?" question. One working lateral pterygoid will cause opening of the mouth and deviation to the OPPOSITE side - in other words, the right lateral pterygoid, working alone, will cause deviation to the left, along with some opening.

 

[Typo]

hi,the answer is ,right condylar neck. forces applied by the muscles, keep the mandible in position.when,a fracture occurs ,muscles cannot exert their forces on the fractured side,where as in the unaffected side,that is the right side,the muscles r in contact with the condyle and they pull the condyle ,causing the mandible to deviate to the unaffected side.

regards,
nikhitha

In the case of injury involving the lateral pterygoid muscle (which attaches to the neck of the condyle and the articular capsule), injury will cause deviation to the affected side. The same goes for damage to the genioglossus (tongue protrusion). Damage to one side of the uvular muscle is an exception, since it will cause deviation to the unaffected side. Hope that helps!

Wouldn't #2 be D? I think the name Streptococcus implies "chains," which makes S. mutans just like the other streptococci. Are there other oral bacteria that make glucan?

well i am not sure about this glucan producing thing, is it glucan or glycan

the newly formed highly vascularised connective tissue associated with inflamation is know as which of the following?

1. scar
2. angioma
3.granuloma
4.purulent exudate
5.granulation tissue



rocknsun

ans is 5

 

[Typo]

It's glucan. Glucan is the scaffolding for plaque, and S. mutans definitely produces it - I think that's what makes it unique.

the ans is left side. mandible always move towards the side of injury so don't ever get confused abt this as i was before...

answer for q 2 is d,it s been already discussed anyway.
on the other hand ,answer for q 3 is supposed to be d cause;a-is irrelevantb-is irrelevant too.c-h f is the precursor of bradykinin met. so it is irrelevant too.acoording to my humble opinion the answer should be d,why?,cause,f o g t is the normal procedure for healing.
thanks
comments critics wellcome 😍

I agree - since ulcerative colitis is limited to the large intestine, it won't impair any type of food absorption.

do you have the new score conversion that is after 1998 ,if yes could you please give the link 🙂 🙂 🙂 🙂

 

[dentethic]

I'm not sure what the question is, but I assume is the final concentration of glucose, which would be 200mg/l.
Good luck on your exam tomorrow!

Isn't it the same 600 (the number of glucose mm/l).


Could anyone explain please.
Thanks in advance

1 liter of glucose with 600ml/l is mixed with 3 liters of water the number of mm/l of glucose is?

GUESS,V'VE FORGOTTEN CHEMISTRY

THATS MILLIMOLES

inciso
mmol=milimole sweety,
mm=milimeter
so??
so which one is it?
mm or mmol

😍

Obstruction jaundice indicates that the bile ducts are blocked, so that means bile won't be getting into the digestive tract. Fat absorption will be negatively impacted.

If the question asks for mm/l, that is a concentration. You are right, the number of mmoles of glucose is the same, but the concentration decreases as you add water. So the answer is 200 mm/l. At least this is how I see it.

Thanks so much Jo23, I got it now.

Two more Qs please
1.In case of Cyanide and apnea which blocks the solute transportation, what way of transportation will the solute use?
Active , Facilitated , or Simple diffusion

2.To transport a solute from its concentration of 5o to 30 will need
Active transport , Simple diffusion

The sympathetic innervation to structures of the head and neck is distributed via the

A. blood vessels.
B. fascial planes.
C. lymphatic vessels.
D. hyoid musculature.
E. cranial nerves III, VII, IX, and X.

Should the answer be A? In Netter's I only see sympathetic innervation traveling with III and VII; the vagus doesn't carry sympathetics as far as I know.

hi everybody ,
i am starting another day,i have 23 more days to go...
anyway
i met this question yesterday,
even though the c ns delivers the parasympathetic fibers,
other sympathetic fs use the same way and the ganglions also for distrubution ie s fs to eye via ciliary ganglion...
so i think the answer is supposed to be e???
what u guy think??

ans is E BECAUSE IX AND X ALSO CARRY SYMPATHETIC INERVATION. BUT IN KAPLAN IT IS GIVEN AS III AS PARASYMPATHETIC SO I AM NOT SURE ABOUT THIS ANS PLS DO RESEARCH ON THIS AND POST THE CORRECT ANS

Where does X supply sympathetic innervation to? I'm mainly posing the question to see if anyone knows any examples where IX and X supply sympathetic innervation. III and VII do carry some sympathetics, yes. But I'm pretty sure that the glossopharyngeal and vagus always supply just parasympathetic innervation (e.g., parotid gland, viscera, heart, etc.). Let me know if you find any examples for sympathetic innervation.

sympathetic fibers come along to the galndular vissera,and the tooth from cervical plexus via normal innervational and ganglial pathway to cranial viscera.

"there is not any hyaline cartilage"this is a correct statement,
but
"collagenous connective tissue" is about the tendons and ligaments,isnot it?
it is a very soft tissue for an articulating surface,
i think the answer is supposed tobe
typical perichondrium???

Definitely not perichondrium - perichondrium is only associated with hyaline and elastic cartilage, and neither of those are in the TMJ. All articulating surfaces of the TMJ are covered by dense fibrous connective tissue, while all non-articulating surfaces of the TMJ are covered w/ periosteum. 100% sure on this; there are tons of questions on old tests regarding this.

Tendons and ligaments ARE made up of collagenous connective tissue, but it's also in the dermis, and other places. It's all over the place.
