Insulin secretion is modified by other nutrients, circulating hormones and the autonomic nervous system, as well as local paracrine and autocrine signals. Autocrine signalling involves diffusible molecules that bind to receptors on the same cell from which they have been released.
The parasympathetic nervous system is associated with food intake and acts on the pancreas to increase insulin secretion. As blood glucose concentration rises, the pancreas secretes insulin to decrease the concentration of blood sugar and store the glucose in the cells. Insulin promotes cell uptake of glucose and also promotes the synthesis of glycogen which is the storage form of glucose inside cells.
