the best faculty of them all

!

Insulin a polysaccharide? true or false?

#1 A patient has difficulty rising from a seated position and climbing stairs- which nerve is injured?

a-superior gluteal
b-femoral
c-obturator
d-inferior gluteal
e-common peroneal

I feel I belong here considering the Institute of Neuroscience is a good chunk health science (I think the woman in charge is school of medicine). So will you accept me here?

As for your questions:

False. Insulin is a polypeptide.

I couldn't even begin to guess at your second question as we've done very little anatomy of the PNS. Once it leaves the CNS we've very little interest unless it's something really remarkable.

snorlax · 21-10-2005 10:49am

yup, welcome aboard

.

i think the answer to the 2nd question is the inferior gluteal nerve (eg bum muscles).

John · 21-10-2005 1:59pm

Indy will tell us for sure what it is

Pet · 21-10-2005 2:00pm

Whenever he finishes his 937234266623863746billion hour week that is.

Chick · 22-10-2005 9:53pm

I'm health science too!

As for the question... I don't listen a whole lot in biology, nevermind understand, but sure I'll go for (d) as a wild guess

snorlax · 22-10-2005 10:02pm

Hey Chick are you on placement at the mo? i saw loads of nurses in James last week and the week before.

how's the study going?

Anyone else find this a little worrying? I'm getting visions of Dr Nick Riviera

DrIndy · 23-10-2005 1:40am

hmmmmmm. straight leg rises is both the quadriceps and the gluteus maximus (to assist).........

People with quads weakness characteristically have difficulty with stairs....

......Femoral?.......

Depletion of which neurotransmitter causes parkinsons disease?

John · 23-10-2005 1:50am

Dopamine.

Where in the brain are dopaminergic neurons mostly found?

DrIndy · 23-10-2005 12:18pm

substantia nigra

what group of bacteria cause syphilis

John · 23-10-2005 12:26pm

A spirochete:

In other news, TCD's new fMRI machine was finally delivered on Friday.

Oh come on lol! No I'm not that bad, I do listen...Honest! I actually have a much better grasp of it than I did last year I reckon so it's all good

Heya! Nope not on placement til Nov 7th. We have classes in James's on mondays and tuesdays, so yeah I probably am one of the nurses that you see floating around the PC room

Study's going grand actually, for once!

wheresthebeef · 23-10-2005 1:54pm

there were loads of nurses in james on friday (protesting)

i take it you are a second year Chick, seeing as how you are in the Trinity Centre at James on monday and tuesday.

Chick · 23-10-2005 1:55pm

I am indeed!

I knew all about the protest yeah. Are you a student nurse as well or another health science course?

snorlax · 23-10-2005 2:07pm

gluteus maximus initiates it the movement though. it's the largest muscle in the body.

Chick · 25-10-2005 6:09pm

Aw man I'm like a week too late on the Parkinsons qs, we did that last friday!

Ok in keeping with nervous system, and seems as no one else has asked another question yet...

What effect does the parasympathetic (autonomic nervous sys) have on the heart?

Probably piss easy for all you geniuses (genii?) but anyway...

DrIndy · 25-10-2005 6:31pm

slows heart rate.

What is sildenafil's mode of action?

I'm grasping at straw's here, but isn't sildenafil the first oral therapeutic agent for erectile dysfunction?

DrIndy · 25-10-2005 6:52pm

but whats the mode of action?

Time Magazine · 25-10-2005 6:57pm

Up and down, and maybe a little from side to side.

John · 25-10-2005 9:04pm

Does it work like viagra as a vasodilator by use of NO signalling?

That's a guess in case you couldn't tell.

Chick · 25-10-2005 9:33pm

Viagra! Indy... well I never

Crash · 26-10-2005 9:29am

well, we already knew he liked to climb poles...

John · 26-10-2005 11:39pm

I never knew he went to Poland!

sildenafil = viagra, so yes

It's a phosphodiesterase-5 inhibitor

Name a drug commonly used in Irish hospitals which in its original form was derived from a common flower.

John · 28-10-2005 1:21pm

Morphine (well the opium poppy is common in places like Afghanistan...)

fade · 28-10-2005 2:22pm

this thread is ridiculous, why not just try pitols at dawn instead.

you see the physics thread was for cool stuff relating to physics, this is just a "how do you know" type thing. pfff, i always knew those health scientists were lesser folks..

LONG LIVE THE ADVANCED MATERIALISTS!!!!

Just because you don't know the answers to the questions no need to get uppity

fade · 28-10-2005 2:58pm

pffff, i did actually, well to the morphine one actually! ive gots lots of interesting knowledge hidden around this brain.

why ask these little trivia questions though? im not normally too concerned with the "what", more with the "why". you biologists get all caught up in names and definitions, yes, morphine can be made from poppies, but how? and how does morphine work? now those are questions that id like to know the answer to!

John · 28-10-2005 5:14pm

I can't remember how it's made but it binds to opioid receptors in the brain (the periaqueductal grey being a main centre for analgesia). These opioid receptors, once activated, modulate activity in many other parts of the brain (affecting serotonin and noradrenaline transmission among other things). This essentially muffles the perception of pain while the drug is in the body.

If you think biology is all about names and definitions then you're sorely mistaken. Mechanisms and modes of action are very much what we're interested in. How can you treat a disease if you don't know what organ it affects and what molecules are involved?

snorlax · 28-10-2005 5:17pm

i'v always found human evolution an interesting subject, do you know anything about it John in relation to the CNS?

John · 28-10-2005 5:20pm

I haven't done it in a little while so I'm sketchy on the details. Let me do some research of old notes and books and I'll get back to you.

ninja 101 · 31-10-2005 10:08am

why is morphine not administered to women in labour as a painkiller?

Ron DMC · 31-10-2005 10:16am

I'd imagine it might have some ill effects on the baby.

WigWam · 31-10-2005 1:38pm

Eh, does one have to be in the faculty of Health Sciences to post here?

wheresthebeef · 31-10-2005 2:45pm

yes. yes one does.

(nah only kidding - probably not. and even if you do, how is anyone to know????? *evil cackle*)

Morphine is not used during Child Birth because it crosses the placenta and causes depression of the Neonates Respiratory System, gastric stasis and increases the risk of Inhalation Pneumonia in the mother.
