Well, it's said (in answers.com) that ansa cervicalis travels upto the carotid sheath and then it sends a branch off to the superior belly of the omohyoid muscle and is then joined by the inferior root.
It doesnt say that it goes to the subamndibular triangle, rather it says to the superior belly of the omohyoid muscle, which is the anteroinferior border of the carotid sheath, and after that the inferior root is formed by C2 which is even inferior to the carotid triangle.
Whereas, hypoglossal nerve travels thru both triangles.
I looked also in the NBDE first aid review and it says there: carotid & submandibular triangle - contend: Hypoglossal n. (to rule anything else out) thanks for clearing that up
👍 this Q is bs ...so confusing - but hypoglossal is the right answer
I have also 2 Q's:
1.The immediate side shift (bennett movement) influences the
A - MD position of the cusps (ans)
B - FL position of the cusps (my answer)
C - Position of the central fossa
D - Depth of the distal fossa
E - Position of the distal fossa
I thought that the bennett movement is a lateral side movement so how does it change the MD position which is more ant.-posts. (facio-lingula makes more sense to me)
2. The dentulous mouth, placing the mandible in the retruded path of closure usually results in...
A - an increase in occlusal vertical dimension
B- an increase in horizontal overlap
C - a decrease in vertical overlap
D - all of the above (ans)
E - none of the above
Would you not raise the vertical dimension if ur cusps are placed in a retruded path ?
can any1 explain that?
