Glucose homeostatic negative feedback system

[TheAnswer]

Can anyone please explain how the glucose negative feedback system works?
There seems to be lots of different information out there which provide different answers.

In short and basically speaking, does it work like this?:
Stimulus: Low/high glucose levels.
Receptor: Pancreas.
Control centre: What part of the CNS does it involve?
Effector:
1. Cells taking up more glucose/releasing more glucose
2. Liver storing more/releasing more glycogen.
Response: Glucose levels rise/fall.

Thanks.

Glucose homeostatic negative feedback system is about an endocrine function.
Are you asking what happens when the CNS is then involved with this endocrine function?

Thanks for the reply.

Basically what i'm asking is that does it involve the hypothalamus or pituitary gland etc. as the control centre? (If it involves one). Is the message gone to there (CNS) where it comes back to say, the liver or pancreas to issue a response?
