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.
Glucose is a source of fuel for the body. An organ called the pancreas makes insulin. The role of insulin is to move glucose from the bloodstream into muscle, fat and liver cells where it can be used as fuel. Insulin is a hormone produced by the pancreas to control blood sugar. People with diabetes have high blood sugar because their pancreas does not make enough insulin, their muscle, fat and liver cells donât respond to insulin normally, or both.
