1 cm beyond foramen cecum: UW question

[Sislo]

I was doing that question on uw where the ask the sensation innervation of the tongue 1 cm distal to the foramen cecum. I immediately assumed its about the region posterior to the septum transversum which receive both taste abd sensation from glossopharyngeal but got ot wrong but it was the corda tympani they said.Now when they say 1 cm distal to the foramen cecum, is it 1 cm anterior to the foramen or it is 1cm posterior to the foramen but befure the septum transversum?Any though????

Apparently only 24 % of people got the q right so makes me feel a little better .Anyone remember that q? Or how would you anwer that and why?

Well since I am sure you know that CN7 innervates anterior 2/3 of tounge and stapedius is a branch off 7......you then know the anwser. wall-la!

DISTAL -meaning the farthest away from your body. This would mean its anterior to the foramen cecum. CN VII for sensation, CN V3 for taste?

 

[perilou]

In reading this post, I fell for the same thing you did. I also thought CN IX. Distal.... bah.

I wouldnt think so other wise what would proximal mean?Posterior to the foramen cecum?

I think what they are asking about was that thing on FA p 131 2009 edition ang stapedius has nothing to do with tongue sensation/taste

Err did you mean CN V3 for sensation and CN VII for taste? Anterior 2/3s of tongue taste is via chorda tympani.

Yep, you're right on that for sure. About the question, I fell for the same thing, knew the innervation but thought the location they were referring to was on the posterior 1/3

 

[BoneNibbler]

To clarify for everyone on the problem : SPATIAL LOCATIONS

always view the question from the patients body. As if you were that patient. So looking from the back to front (as if ou were inside) and distal to cecum is the anterior tongue.

I mean when the question says "the patient has a swollen LEFT arm"...do you think they mean the patients arm according to your left?? No, everything is from the patients persepective.

Hope this helps!!

No you're over simplifying the term.
Distal means farthest away from the ORIGIN, which is the same thing as farthest from your body for most things, but stops working for the GI tract.

In the GI tract you start at the mouth and move distally to the anus. So the small intestine is more proximal than the large intestine, the transverse colon is distal to the appendix, etc.

When it says 1cm distal to the foramen cecum its saying further into the mouth, so POSTERIOR in that case.

Yes I had the same feeling and problably 1 cm posterior to the foramen cecum but before the sulcus terminal which is the line where the circomvalate papillae are found and divide the ant 1/3 from the post 2/3 of the tongue. Now how far is the sulcus terminalis from the foramen cecum? I guess its more than 1 cm?? correct me if Im wrong.I could see why only 23% of people got that question correct

you would be right if the tongue was part of the gut tube. the tongue arises from the pharyngeal arches and grows outward (distally) through the proximal gut hole. therefore anterior and distal mean the same thing in this regard.

its all relative baby

 

[Disinence2]

I got this question right.

Just think of the tongue like an appendage.

WRONG.

it is "anterior". He thought it was posterior and got the question wrong.😴

 

[sprinkibrio]

They definitely said distal was tip since the tongue is not GI tubage. They asked for pain and somatic sensation which is V3. Taste is the chordae tympani. I just had the question today.

Got this right; was a lucky guess
