each of the foll required for viral antigen recognition by CD4+ T helper cells except :

-viral replication in host cells
-cleavage of viral proteins into small peptides
-transport of viral peptides to a cell surface by MHC class II molecules

-binding of the T cell's tcr to MHC class II bound viral peptide

-internalization of virus ( or viral protein ) by an antigen presenting cell

Ifthe facial nerve were to be cut just after it
exited the stylomastoid foramen, it would
cause loss of innervation to which of the
following?​
​
​

  1. lacrimal gland​
  2. Mylohyoidmuscle​
  3. Submandibular gland​
  4. Orbicularis oculi muscle​
  5. Anterior belly of the digastric muscle
Enlargement of the third ventricle and both
lateral ventricles is caused by obstruction of
the​
  1. cerebral aqueduct.​
  2. foramen of Magendie.​
  3. foramina of Luschka.​
  4. interventricular foramina of Monro.
When both dentitions of the human are
considered, which of the followingrepresents,
in years, the lifespan of the dental lamina
​
  1. 1​
  2. 3​
  3. 5​
  4. 9​
  5. 12​

facial nerve after exiting the stylomastoid formen gives rise to

buccal/mandibular/temporal/zygomatic/stylohyoid/post auricular/diagastric branches.

Zygomatic n temporal supply the orbicularis oculi.

Cerebral aqueduct connets the 3rd ventricle to the 4th ventricle. Since lateral n 3rd ventricle are invloved obstruction is distal to 3rd ventricle.

The last tooth to show first evidence of calcification is man 3rd molar by age 9. Dental almina is functionally complete.

r u really sure that the life of dental lamina is 9 years ?
according to orbans the toatl activity of the dental lamina is 5 years
dental lamina disappears after the initiation .then the initiation of the 3 rd molar is 4 th or 5th year of life according to orbans then i think the nas should be 5 years
please correct me if wrong

How it can be long after PDL disease , it itself the cause for periodontitis??????????????????

yup Gaya is right , life span o dental lamina is 5 yrs , i have thoroughly checked on webiste too

hi,

actually i have this same question in my decks.. i as u guessed thought that it could be jusr bfor periodontitis.. but the answer given was long after the beginig of gingival desiase


this book that i read mentions that dental lamina is the only tissue that has the unique ability to give rise to tooth germ thicknenig... and under no circumstances are 3rd mmolar toothbud evidence at age 5.. so pls can forward the source of u r info.. the website..

yaah u r right 3rd molar calcification start at 7-8 or even upto 9 years
so dental lamina age should be upto 9yr

Ans:
1) Increase in CO, this will Shift the Hb dissociation curve to left.
2) Vagus

hi

you are right!! I got this wrong this time too.. 🙁(( co moves the curve to left. While respiratoy acidosis will increase the hco3 whic ll increse the ph so moves to right.. Sorry for the mistake..

HI ITS NOT MWNTIONED CLEARLY IN MY BOOK BOUT DENTAL LAMINA.. ALL IT SAYA IS, THAT DENTAL LAMINA IS THE ONLY TISSUE THT HAS THE ABILITY TO GIVE RISE TO TOOTH GERM AND THT IT UNDERGOES DISSOULTION FOLLWING FORMATION OF ALL TOOTH GERM, U CAN SAY I APPLIED MY LOGIC, SINCE NO TOOTH GERM FOR 3MOLARS IS AVAILABNLE AT AGE 5 BUT IF ORBANS HAS CLEARLY/PRECISELY MENTIONED THT DENTAL LAMINA IS ACTIVE FOR ONLY 5 YEARS, I LL GOW TIH THT. SO PLS READ THT STUFF AGAIN IF POSSIBLE N CONFIRM, I HAVE MENTIONED WHT WAS AVAILABLE FRM MY SOURCE OF INFO..
