Hi Mekha

I managed to find it in a textbook today. It's definitely loose.

I'll try looking up the answer for the collagen. I'll let you know when I have it....if I could find it :).
Thanks for your answer.

The dominating type of collagen in the pulp is type III with lesser amounts of type I and VI

56. Which of the following arteries is usually the most inferior branch arising from the external carotid artery?

a) Superficial temporal
b) Posterior auricular

here i guess the answer is ---- sup thyroid but what if there was one more option of --ascending pharyngeal included then what would be the answer.???????????

left rec laryngeal pass beneath
a)lig arteriosum
b)left sup intercostal vein

left recurrent laryngeal nerve orginate from left vagus nerve it pass over the arch of the aorta inferior to left superior intercostal vein. It goes medially and posteriorly deep to ligamentum arteriosum before curving inferior to the arch of the aorta. It then passes superiorly over the left main bronchus to ascend in the groove between the left side of the trachea and the ant of the esophagus.


so what could the ans be lig ateriosum or lft sup intercostal v?

2)primary elevator of mandible except one ,exception
mylohyoid
lat pterygoid
temporalis

is the answer mylohyoid

left recurrent laryngeal goes beneath the left sup intercostal first and
around (hooks) lig arteriosum,


relation of left rec laryngeal to lig arteriosum is posterior and medial first and then it hooks

relation of left recurrent laryngeal is inferior to left sup intercostal v

i thought inferior was beneath ,so intercostal as a probable answer



and abt lateral pterygoid in jeferry okeseon it says sup head of lateral pterygoid helps in chewing(power stroke) and mylohyoid just opening only ,



http://www.thetmjdoctor.com/skullmovie/uprightnormal.html

4 th paragraph in this site says too


All the fibres of the inferior head are attached to the anterior suface of the neck of the condyle. Hence, contraction of the inferior head pulls the condyle forwards and downwards, protruding the mandible. Some fibres of the superior head are inserted into the anteromedial aspect of the capsule and disc (Carpentier et al., 1988). Contraction of the superior head thus pulls both the disc and the condyle forwards. Since its origin is above the condyle, it also assists slightly in elevation (Koolstra and van Eijden, 1995) .


i know mylohyoid ,which is from mylohyoid line to hyoid muscle has only opening action

i dont know what to consider as answers for these questions.now i really have anterior open bite with posterior gagging :eek:

hi Ridge,
i think u didnot read my quary completely ----

what i am asking is if the options where (lets just change the options here ,u know the questions asked in the exams will not be the same as previous years ,some changes in a question should be expected )
---
a) Superficial temporal
b) Superior thyroid
c)Ascending pharyngeal (another branch of external carotid )

with these options which one would then be the most inferior branch of ECA .
thanx!!!!

I get quite confused about this question. All of the options are elevators of the mandible EXCEPT mylohoid ( which depresses the mandible when the hyoid is fixed) and also the lateral pterygoid which also depresses the mandible. So why is the answer lateral pterygoid and not mylohyoid or both (which of course is not an option)?

Lateral Pterygoid Muscle


From an anatomic viewpoint, the lateral pterygoid is generally described as one muscle arising from two distinct heads. From a functional viewpoint, however, the lateral pterygoid consists of two separate muscles: the inferior lateral pterygoid and the superior lateral pterygoid.

The larger inferior lateral pterygoid (ILP) originates from the outer surface of the lateral pterygoid plate of the sphenoid bone and runs backward, upward, and laterally to insert on the anterior surface of the neck of the condyle. The smaller superior lateral pterygoid (SLP) arises from the greater wing of the sphenoid and fuses with the inferior belly near its point of insertion. Fibers from both bellies insert into the neck of the mandibular condyle. Some researches believe that a small, variable number of fibers from the superior belly also insert on the anteromedial border of the articular disc. Other researchers were unable to demonstrate a direct attachment to the disc, but were able to show a connection to the anterior aspect of the TMJ capsule. This connection increases the possibility that the SLP may influence disc movements without inserting directly on the disc. Despite the lack of consensus about the structural organization of the SLP, this text will assume that the SLP does have a role in anteroposterior movements of the articular disc during joint function.

Studies have shown that the two heads of the lateral pterygoid function as independent and antagonistic muscles. During mandibular opening and protrusion, contraction of the ILP pulls the condyle forward down the articular eminence. In contrast, the SLP is active during mandibular closure and contracts in conjunction with the mandibular elevator muscles.

The SLP exerts a holding or bracing action on the condyle when the teeth are held together and during power strokes. A power stroke occurs during forceful mandibular closing, especially during chewing or during clenching the teeth. The SLP also acts to rotate the disc anteriorly on the condyle when the disc condyle complex is moving upward and backward against the eminence. By keeping the disc between the condyle and eminence, the SLP helps to maintain joint stability.

may be this can clear a few doubts .
