most abundant in dental plaque-S.mutans.what is the ans for above question?

which is least likely to infect a bum lesion?
a)C.tetani
b)S.aureus

C.tetani would be my answer.........aureus and aero are definitely most likely and ulceratum is a possibility because of the kind of lesion.

It passes through both.

 

[make you smile]

spinal accessory nerve passes through which foramina??
jugular foramen or foramen magnum??

Spinal accessory nerve enters the skull thru foramen magnum and exits the skull thru jugular foramen.

 

[uabsfm]

ans for first ques-S.sanguis

it is BUM lesion,not burn lesion.....

what is BUM lesion ,will you plz clear it?

 

[uabsfm]

spinal accessory nerve passes through which foramina??
jugular foramen or foramen magnum??

spinal accessory nerve passes through both foramina because it arises from the upper part of the spinal cord ,enter through foramen magnum through skull and then with nerves 9th and 10th it will come out from skull through jugular foramen.

 

[pbkal]

Spinal accessory nerve enters the skull thru foramen magnum and exits the skull thru jugular foramen.

hi
thanks for the ans..

In Hydrocephlus excess CSF is found within which of the following

1)Ventricle
2)subdural space
3)Cisterna Magna
4)Subarachnoid space
5)Superior Sagital Sinus


In erytropoiesis which of the following increases from Proerythroblast to mature erytroblast

a)cell size
b)phagocytic ability
c)cytoplasmic acidophilia
d)cytoplasmic basophilia



The main route of calcium excretion in humans is?

a)feaces
b)urine
c)saliva
d)sweat
e)tears

 

[toothfairy482]

sorry, the answer to that is D. Greater than 2.
The way you figure it out is at P50=26torr and at this 2 oxygen sites on the Hb are occupied...so at 30 torr a little more than 2 will be occupied.

(b) is sure.what abt (a) and (c)??

 

[aphistis]

well!!how will we know that 2 oxygen sites r occupied at p50=26torrs?pls explain..

Because that's empirically how hemoglobin-oxygen binding works. P50 means half of the binding sites on hemoglobin are bound to oxygen. Since a hemoglobin molecule has 4 oxygen-binding sites, at P50 two of the four will be bound to oxygen. There's no way to simplify it any further; if this still doesn't make sense, you need to review this topic in a basic physiology textbook and learn the material.
