Dear friends,
so here I am starting the discussion from today .
we will start with neurology today .
below I am sharing some problems[in question formate] with you which are constructed to ignite the discussion procedure .
now as I have started this page of this forum I will make a open appeal to every serious member who visits this page. That is pls type all the related material you want to type in one place & then post it [ each time you post]; so every members message at the time of posting can be seen in limited space in one place. It probably becomes boring to read single lines at big big gaps [ take it easy its just a request , you are free to write as you want bcos ur participation is imp for us].
Some tips before you start answering
1. answer in chronology
2. use appropriate question no. to answer [it makes things easier to read & understand for other viewers]
3. pls don’t refer to book while you answer bcos no one is going to scold you if you answer wrong. [you may refer to book after you have finished answering ]. If you answer honestly you can judge ur knowledge & logic power. Above all you make mistake now probably you don’t make it again.
4. you are encouraged to attempt every question
5. try to justify [I mean explain with logic] every answer of urs on the basis of sound biomedical & clinical knowledge you have.

Here goes the first question set for discussion - SET-1

SET -1

1. foot process of what surrounds the capillaries at BBB[bl. Brain barier]?
2. what is the effect of endorphin as a neurotransmiter– excitatory or inhibitory?
3. which cell lines the cerebral ventricle?
4. name the anatomical structure essential for surrounding axon & transmit axn potential via saltatory conduction?
5. which cells form myelin sheath?
6. in pain to occur which neuropeptide plays the most imp role ?
7. during neuro transmission which specific event causes fusion of synaptic vesicles containing neurotransmitter to presynaptic membrane ?
8. mention any 2 very common causes of headache in elderly population ?
9. a 65 yr old pt came to ur clinic with history of severe headache . acording to him the pain precipitated while he was eating meat & bread in his sons 25th birthday. On neurologic exam you found the pain to be more in 5th nv area. What is most probable dx you will make before you proceede for any furthur investigation?
10. a lady who is married for last 8 yrs & has 1 male child comes to you with history of migraine with aura. She also gives history of using OCPs for last 5 years .
a. will you advice to continue her with same contraceptive device or you want to change it?
b. If you change it state why you want to change it? [ ur answer must be relevant to the above mentioned case]
11. a 32 yr old pt went to his physician with complain of aute onset severe headache just after sexual intercourse at early morning. His physician adviced him to undergo a CT scan . he had no similar previous history.
a. now do you think his physicians approach to his pt is correct?
b. If you support his approach justify why?
c. If you were the physician would you had ordered any additional investigation?
d. If yes what would you had ordered & why?

WELL FRIENDS I HOPE You LIKE THE APPROACH. PLS VOTE ME SO THAT I CAN EVALUATE MY SELF.
UR ADVICE/CRITICISM TO ENRICH THE DISCUSSION PROCEDURE IS AWAITED.
FOR EXHAUSTIVE DISCUSSION ON MANY OTHER TOPICS PM ME WITH UR E-MAIL ADDRESS [[snip] PREFFERED], BCOS DISCUSSION IN THIS PAGE WILL BE A QUITE SLOW PROCESS BCOS TILL WE HAVE ENOUGH DISCUSSION by enough no. of participants I CANT KEEP the SET-2 FOR DISCUSSION.

answers set1
1-astrocyes
2-both
3-ependymal
4-myelin sheath
5-oligodendrocytes
6> substance P
7> entry of calcium ion
8-giantcell arteritis and cluster headch
9-trigeminal neuralgia
10-stop ocp pills becoz they aggravate migraine;wheneever a patient has migraine with aura & simultaneously history of use of ocps there is a INCREASED risk of having stroke in future.

Ans of question11 >
[a] yes correct
bcos history indicates it may be a sub – arachnoid hemorrhage

Neuron A is excitatory to Neuron B. Neuron C provides a presynaptic inhibitory input to Neuron A at an axo-axonic synapse. Neuron A is active. If Neuron C becomes active as well, which of the following will likely happen?

a: Neuron A will produce fewer action potentials as a result of inhibition.

b: Neuron B will receive i.p.s.p.s from Neuron A.

c: Neuron A will release more transmitter onto Neuron B.

d: The probability that Neuron B will reach threshold is decreased
