The IXth nerve has no real nucleus to itself. Instead it shares nuclei with VII and X. The sensory information in IX goes to the solitary nucleus, a nucleus it shares with VII and X. All motor information, essentially the innervation of the stylopharyngeus muscle, comes from the nucleus ambiguus, also shared with X.

Pls correct if wrong!

thanks

Sorry, i read the 1st option as adrenal medulla..that would be the right answer...its not the renal medulla.

Derivatives of Neural Crest Cells
Spinal ganglia (prevertebral/paravertebral)
Ganglia of the autonomic nervous system (ANS)
Ganglia of cranial nerves V, VII, IX, X
Sheaths of peripheral nerves
Meningeal coverings of brain and spinal cord
Pigment cells (melanocytes)
Adrenal medulla
Odontoblasts of tooth

[anjali_45]

yes u r right i also read it as adrenal medulla that shud not be the answer
everybody please correct renal medulla is not the right answer
i think it is preganglionic of sympathetic.
do correct me if i am worng

well answer is preganglionic sympathetic cell bodies [autonomic nerveous system]

renal medula arises from the endoderm

hi
cud u plz tell me how u arrived at choice of anterior sclanus muscle
as far as i knw investing layer of deep fascia splits between two layers superficial n deep
to incorporate in between
trapezius and SCM
im nt sure of other choices also i tried to find but cudnt find
let me knw how u arrived to this answer?

 

[rtvj]

thats why i have put 2 question marks after the choice!!
Even i searched but culdnt find the right answer...only thing was i culdnt find anything relating anterior scalene muscle and deep fascia in any of the books or articles i went thro.

[aerotech]

i am pretty sure the answer is "postganglionic sympathetic cell bodies' b/c the neural crest gives rise to sympathetic ganglia (so the postgang cell bodies are in ganglia)...the neural crest gives rise to ADRENAL MEDULLA...i don't think you can assume it's the renal medulla (deriv of either ecto or mesoderm).

 

[anjali_45]

u r right
i did a mistake of reading it quickly and jumping to conclusion
that is why i corrected myself but i did not find the right answer

sorry..i hope you didn't feel i was bashing you...i apologize...i didn't want anyone to get this wrong on the test...i myself chose renal medulla initially b/c i read it so quickly...best of luck!!
