<prompt> Insulin release is inhibited by:SomatostatinGlucagonAcetylcholineAmino acids  <response>: Somatostatin, secreted by d cells of pancreas, inhibits the other two secretions of the endocrine pancreas - insulin glucagon. The primary stimulators of the somatostatin are glucose, amino acids, and fatty acids. Parasympathetic nervous system vagusAch is a stimulator of insulin secretion. Insulin secretion is inhibited by epinephrine acting alpha-2 adrenergic receptors. Amino acids, FFAs, and glucose are the stimulators of insulin secretion.
