ARTHROPODA
The organizations of arthropod endocrine systems parallel those of the vertebrate endocrine system. That is, neurohormones are produced in the arthropod brain (analogous to the vertebrate hypothalamus) and are stored in a neurohemal organ (like the vertebrate neurohypophysis). The neurohemal organ of insects may have an endocrine portion (like the vertebrate adenohypophysis), and hormones or neurohormones released from these organs may stimulate other endocrine glands as well as nonendocrine targets
