HI
I was just wondering, did anyone else do the essay on the pituitary gland and the drugs affecting feutal development in section C?

I did, and even though it was a non structured one i stil felt there wasn't enough things to write about!
The only points i made were:

pituitary produces TSH which goes to the thyroid and makes it produce thyroxine which stimulates cell metabolism.... and it produces growth hormone which increases uptake of a.a's into bones and tissue

then.. thalidomide cAUSES abnormal limbs, and nicotene and alcohol stunt mental development and physical growth

Ive checked my notes but dont seem to have missed anything but that seems wayyy to little for 10 marks, what do you think??

there was a lack of points for the pituatry, but i thought that there was plenty for the second part.

I wrote about thalidomide, alcohol and nicotine. So if each of them was to have 2 marks each, then that's 6 marks, then that only leaves 4 marks for pituatry. And for those I think you'll get them for mentioning;

thyroid stimulating hormone (1)
human growth hormone (1)
folicle stimulating hormone (1)
and lutenising hormone (1)

and possibly also mentioning that FSH and LH are gonadotrophic and that HGH is somatotrophic (1)

Remember that in the second section you only get 8 marks for KU and then one for relevance and one for coherence. I did that essay too btw. smile.gif

i dunno if they're actually in the syalabus (sp) but our teacher told us about them

FSH & LH target the gonads (testis/ovaries)
when genes are switched on in the pituatry cells, FSH or LH is produced. This usually occurs at puberty

They aren't in the Higher Biology course but they are in Human Biology. So if you've not heard of them don't worry, you're not meant to!
The race is long, and in the end it's only with yourself.

I did this questions too. i divided it up into 2 sections and first wrote about the TSH and somatatrophin. Also mentioned a bit about how the PG was the overall regualtor which regulated these hormones by negative feedback control. But mostly focused on the effects as didn't want to lose the mark for relevance!

The drugs one; by that time I was pushed for time so just scribbled about nicotine as a stimulant and effects on CNS (careful not to confuse with cigarette smoke in general which was annoying) and foetal alcohol syndrome and thalidomide effects.

Looks like we're all on the right track!
