Blood Glucose Regulation

[Drunk]

Hey guys,
Stupid question, I know, but I just wanted to make sure I had everything right
If I were to use the example of regulating high blood glucose and put it into a stimulus-response model, would I get

Stimulus - High blood glucose
Messenger - ?
Receptor - islet cells of Langerhans in pancreas
Messenger - ?
Coordinating centre - islet cells of Langerhans in pancreas?
Messenger - ?
Effector - alpha and beta cells
Response - increased insulin, decreased glucagon

Could someone help me fill in the blanks and check if I got anything wrong? Thanks!

hmmmm
Stimulus - High blood glucose
Messenger - not sure what you mean by messenger. i dont think there is one here
Receptor - chemoreceptors on pancreatic beta cells
Messenger - not sureee
Coordinating centre - islet cells of Langerhans in pancreas (which releases insulin)
Messenger - insulin hormone
Effector - all cells, but specifically skeletal muscle and liver cells (sometimes fat tissue too)
Response - increased insulin, decreased glucagon <-- this is not the response of insulin responding to high blood glucose; this is ---> Decreases blood glucose levels

I'd assume the messenger would be either a chemotransmitter without actually knowing... dunno how much detail they'd want you to go into for that?

Responce - alpha cells increase insulin production and beta cells decrease production of glucagon. unless i have the alpha and beta the wrong way around.

I'd assume the messenger would be either a Neurohormone or a Neuotransmitter without actually knowing... dunno how much detail they'd want you to go into for that?

why though? i dont think the brain/NS is involved in glucose regulation

Response- Increased uptake of glucose by liver and skeletal muscle cells and the conversion of glucose to glycogen for storage. I think.

o yea this is right. and then just include that it decreases blood glucose levels (back to narrow set range)

Oops, chemotransmitter* not neuro.
