in reference to the first Question the answer is : Retrodiscal tissue witch it contains (bilamenar zone ;posterior attachment).
the retrodiscal tissue is highly vascularized and inervated ,whereas the articular disc for the most part is no.only the extreme periphery of the articular disc is slightly innervated. 🙂

WHY DOES IT SAY "nEWLY ERUPTED??

BECOS GENERALLY EACH LOBE OF THE TOOTH WILL HAVE A PULP EXTENSION

hey guys, thanks a lot for all your efforts........i appreciate a lot......but still i have confusion to thickest portion of aricular disc???retrodiscal,post att or bilaminar zone........

Also, is collateral ligament temporomandibular ligament only???


AND, ans to 5 is b only.......i read in wheelers........book of DA
ONCE AGAIN THANKS TO ALL WHO HELPED ME........STILL WAITING TO CLEAR MY CONFUSION.....

COLLATERAL LIG IS NOT TEMPOROMD LIGAMENT.THEY ARE ALSO CALLED DISCAL LIGAMENTS ATTACH ARTICULAR DISK TO LATERAL AND MEDIAL POLES OF THE CONDYLE .LIMIT MOVEMENT OF DISK AWAY FROM CONDYLE THAT IS HELP IN ANTERIOPOSTERIAR MOVEMENT OF DISK ON THE CONDYLE
TEMPORO LIG= LATERAL LIG
TELL ME THE ANS OF 3 ITS TRICKY

hey aaram, i read bout pulp horns today in DA wheelers ...........its says that There are projections or prolongations in the roof of the pulp chamber that corresponds to the various major cusps or lobes of the crown.The pulpal tissues that occupy these prolongations are callled PULP HORNS. The prominence of the cusps or lobes corresponds with the development of the pulp horns.If the cusps or labial lobes are prominent(ie. young individuals n newly errupted teeth) we should expect to find equally prominent pulp horns underlying these strs. These projections become less prominent with time as a result of the formation of sec dentin......pulp horns are also found in mammellons of maci incisors when teeeth are young


I hope this helps u
