what is the function of transitional epithelium and how does it differ from squamous epithlium?
what is the virulence factor of n. meningitidis?
lingual frenum is attached to what muscles?
what muscles are responsible for blinking of the eye?

 

[docasrpa]

transitional ep can expand..present in urinary bladder

 

[docasrpa]

i think the capsule is virulent factor in neisseria

 

[porcelain258]

lingual frenum attached to genioglossus
musles responsible for blinking sphincter musles...not sure about this

 

[dental degree]

transitional can stretch , squamous cannot
lingual frenum atteached to genioglossus

 

[anudoc]

lingual frenum attached to genioglossus
musles responsible for blinking sphincter musles...not sure about this

the muscle responsible for blinking is orbicularis oculi . It is spincter muscle of eye lid

 

[dental degree]

N. meningitis virulence factor is endotoxin since it is gram negative.
blinking is due to both orbicularis occuli(closing) and levator palpebrae(opening) i think. correct me if im wrong

 

[coming to terms]

the virulence factor for neisseria is antiphagocytic capsule.

 

[econservative]

what is the function of transitional epithelium and how does it differ from squamous epithlium?- it can be stretched and the only place for it to be present is urinary bladder
what is the virulence factor of n. meningitidis?- Anti phagocytic capsule
lingual frenum is attached to what muscles?- genioglossus
what muscles are responsible for blinking of the eye?-There are multiple muscles that control the reflex of blinking. The main muscles, in the upper eyelid, that control the opening and closing are the orbicularis oculi and levator palpebrae superioris muscle. The orbicularis oculi closes the eye, while the relaxation and contraction of the levator palpebrae muscle opens the eye.

please correct me if i am wrong

i think its fsh as it doesnt have any role during pregnancy
lh produces estrogen n preogesterone early in pregnancy but after that even lh has no role.

Hi, taking exam really soon. I need help on these questions. Please help!!

Which of the following proteins is least likely to be found in fully developed mineralized hard tissue?

a. Osteopontin
b. Osteonectin
c. Tuftelin
d. Endothelin
e. Bone Morphogenic Protein (BMP)


Which of the following protiens is least likely to be found in fully developed fibrous connective tissue?

a. Fibronectin
b. Osteonectin
c. Collagen
d. Elastin
e. Vimentin

I think the second one is Vimentin and the first one i have no clue.help

 

[docasrpa]

endothelins. these are vasoconstrictors. NO and adenosine are dilators

vimentin is a dynamic protein that forms cytoskeleton

 

[Sinatra Frank]

from did u find these question? i don't recall reading material related to that.. i will thank u if u can give me refrence for the questrion and the answer.

have a good day

Vimentin is an intermediate filament associated with mesenchymal cells.
so i guess the answer then should be osteonectin.
osteonectin is useful for bone mineralisation.
