correct me if i am wrong

Hi Ice2remember,

9. The bone composing the cortical plate of the alveolar process consist of which of the following
a. canc bone with wide marrow space
b. canc bone with reduced marrow space
c. haver system and circumference lamellae(may be)......?
d. haver system but no circumference lamellae
e. circumference lamellae but no haver system (I think as there are no haver syst in alveolar process..)

Can you please explain why you pick option C.....?

u r right.......

 

[drvijigobs]

hi thanks for your reply...

for 2nd question i thought simple cuboidal because in cause of straited duct its simple cuboidal

for 5th question ciliary ganglion is pre ganglionic parasympathetic but its post ganglionic sympathetic so the should be intermediolateral thoracospinal


correct me if i'm wrong!

 

[nisreen]

Q:5. cell bodies of postganglionic sympathetic fibers to the eye are located in the superior cervical ganglion. preganglionic sympathetic fibers originate from neurons in the intermediolateral column at T1-T2 level and form synapses in the superior cervical ganglion..

 

[nisreen]

striated ducts of parotid glands are lined by a layer of tall columnar epithelium and the intercalated ducts are lined by a single layer of low cuboidal epithelium.. ref: orban's oral histology and embryology

 

[nisreen]

the cortical plates consist of longitudinal lamellae and haversian systems, in the lower jaw, circumferential or basic lamellae reach from the body of the mandible into the cortical plates

 

[drvijigobs]

thank you .nisreen...

so the answer for 9th is haversion system with no circum lamella

 

[nisreen]

i think the answer would be haversian system and circumferential lamellae...i'll read up a little more on it and try and get a confirn answer

thanks.i have got to read the questions more carefully.........

Hi Viji

Would be really greatful if you helped me with the part 1 study.

[cutedoc12]

i think da ans s hav system nd no circumferential lamellae coz longitudinal lamellae r present

 

[amita]

hiii...thr...i jst read in review buk tat haversian canals do hv circumferential lamellae....thank u
