Some other large and small islets are located in the mesenteric arteries near the gallbladder and bile ducts. Since hormones do not take part in any biochemical reactions, hormones are called autonomous or autocoides. However, as a result of the proliferation of multiple branches of the parenchyma (Neurohypophysis), it can be easily distinguished from meta-adenohypophysis.
