Insulin and Pancreatic Islet Function: Hormonal Regulation of Glucose Metabolism #3313702 (License: Personal Use)

The image depicts the Islets of Langerhans within the pancreas, highlighting alpha cells (glucagon), beta cells (insulin), delta cells (somatostatin), and F cells (pancreatic polypeptide). Insulin secreted by beta cells promotes glucose uptake in the brain, suppresses gluconeogenesis in the liver, and inhibits lipolysis in white adipose tissue-key mechanisms in maintaining metabolic homeostasis.

Used in medical education, endocrinology resources, or diabetes-focused health websites to explain insulin physiology and pathophysiology; matches user intent for understanding hormonal regulation of blood sugar.
