Help/.. !!!!KARMA!!!~~

My friend has a sac tomorrow and he wants to clarify few things
 "
Using a typical negative feedback diagram, show what actions are taken to monitor a rise in blood sugar level
 or a fall in blood sugar level
 Both diagrams need to include the following: the stimulus, the receptors, the effectors the responses"
A diagram and an explanation on the stimulus, the receptors, the effectors would also be nice
THANKS~~~

I think theres a diagram like this inside nature of biology

Edit: Well i was bored and procrastinating so i made a very quick version sorry about the crappy writing lol

When its low, its slightly different.

Alpha cells release glucagon which increases blood glucose. (By converting stored glycogen into glucose .)

[slothpomba]

If you mean glycogen its stored in liver and muscle tissue

I would say differently....

Stimulus: High Blood sugar
Receptor: Pancreas
EFFECTOR: LIVER CELLS AND SKELETAL MUSCLE CELLS
Response: Lower blood sugar..

[slothpomba]

Explain

[simpak]

Receptor has to be more specific than 'pancreas' by the way, you should say 'cells in the pancreas'.
Your problem that you have identified is due to this not being a negative feedback diagram.
It's not the correct format so it's not obvious what the effector should be
No offense to your diagram!

But yeah, if you would like me to I can possibly go to the trouble to make one that I would have done in response to the question.

In drawing a stimulus response model, does there always have to be the 'control centre' box? Or can the model be drawn correctly without it?

Sorry for digging up the thread
