Dental Deck mistake

The decks state that carboxypeptidase A cleave aromatic amino acids, and basic amino acids, lysine and arginine

this is wrong

Carboxypeptidases cleave the C-terminal residue or polypeptides. Carboxypeptidase A does NOT cleave C-terminal Arg or Lys residues, or ANY terminal residue that is next to Proline.

What the statement was referring to was carboxypeptidase B

If you guys find any other mistakes, just post em here

These are corrections/clarifications as listed on the dental decks website...you can check as they periodically update.


Dental Decks Part I 2004 Edition

Section: Anatomic Sciences
Category: Rsp S
Card: The nasal cavities are lined by:

Correction: The third answer choice on the front of the card should be: Specialized columnar epithelium

Correction: The answer on the back of the card should be: Specialized columnar epithelium (also called olfactory epithelium).

Clarification: Also on the back of this card, #4 under Notes should read: This specialized columnar epithelium, called olfactory epithelium is very prominent in the upper medial portion of the nasal cavity.



Section: Anatomic Sciences
Category: Pdl/G
Card: Surrounding each tooth is a specialized epithelium known as a:

Clarification: The question should read: Surrounding the root of each tooth is a specialized epithelium known as a:



Section: Anatomic Sciences
Category: Bn
Card: Which fossa is a shaped space lying posterior to the maxilla, between the pharynx and the ramus of the mandible?

Correction: The question should read: Which fossa is found posterior to the maxilla, between the pharynx and the ramus of the mandible?



Section: Anatomic Sciences
Category: Nrv
Card: The mylohyoid muscle receives motor fibers from the:

Correction: The answer should be: Nerve to mylohyoid (branch of V-3)




Section: Microbiology / Pathology
Category: Dis
Card: The heterophile test is used for the diagnosis of:

Clarification: The first answer choice on the front of the card should be: Infectious mononucleosis



Section: Microbiology / Pathology
Category: Vir
Card: The cytopathic effect that is seen when a virus infects a specific cell culture:

Correction: The answer should be: Is characteristic of each virus and can be used for detection of that virus.

Anatomic Sciences: One of the cards states that the differentiation of odontoblasts from the ectomesenchymal cells of the dental papilla is induced by the newly-secreted enamel. This is incorrect -- differentiation of odontoblasts from the dental papilla cells is induced by inner enamel epithelial cells (ameloblast precursors) themselves, before they have the capacity to produce enamel. Mantle dentin is then secreted by the odontoblasts, which brings about the differentiation of ameloblasts and subsequent secretion of enamel.
This point is repeated several times, and there seems to be this confusion on only one card.

Another Anatomic Sciences: As a NOTE in the back of one card concerning the GI system, it says "ileal" (or "ileac"?) refers to the hip bone. This should read "iliac," as in the iliac crest of the os coxa; ilEum refers to the small intestine.

The NONARTICULAR surfaces of the TMJ are covered with:

a) fibrocartilage
b) periosteum
c) hyaline cartilage
d) elastic cartliage

The answer is periosteum

My prof says:

The answer on the dental decks is technically incorrect. There is no
periosteum within the confines of the TM joint capsule. That is the
reason for blood supply to the condyle coming from terminal branches of
the superficial temporal artery posteriorly and terminal branches of the
artery to the lateral pterygoid anteriorly. The articular surface of
the condyle is composed of fibrocartilage. There is no hyaline
cartilage in the TM joint.
However, for purposes of answering the question...the closest correct
answer would be periosteum.

Good advice. When it comes to ANY dental board exam, you choose the answer they want you to choose, not always what is correct. Good luck.

This question has been on nearly every old exam back to the early 80s -- they all list periosteum as covering the non-articular surfaces and fibrocartilage lining the articular surfaces. A few wanted you to know that most diarthroses are lined by hyaline cartilage, and the TMJ is an exception to this rule.

I'm taking this beast on Saturday...man I hope I do okay!

thanks for the info.. good luck!!
