Based on
the traditional model for the neural control of energy homeostasis, which
statement accurately reflects the receptor distribution and hormonal response
of ARC neurons?

Question

Accepted Answer

AgRP neurons express the ghrelin receptor (GHSR) and are activated by ghrelin, whereas POMC neurons express leptin and insulin receptors but do not express GHSR.

Answer

Positive energy balance causes a decrease in leptin levels, which subsequently inhibits POMC neurons to prevent hyperglycaemia.

Answer

Both AgRP and POMC neurons express the ghrelin receptor (GHSR), allowing the stomach to directly activate both populations simultaneously.
