Accessibility They are originated Bethesda, MD 20894, Help A subgroup of neurons in the classical X‐organ‐sinus gland neuroendocrine system of the crayfish (Orconectes limosus) eyestalk produces two chiral forms of the crustacean hyperglycemic hormone (CHH) in two different types of neurons: CHH in ∼22 cells and D‐Phe 3 CHH in eight cells.Previous reports have demonstrated that release of CHH from the sinus gland is inhibited by enkephalins. The sinus gland is an important part of an elaborate neurosecretory system in the eyestalk of stalk-eyed crustaceans and in the head of sessile-eyed forms. The Journal of Crustacean Biology is the official journal of The Crustacean Society, publishing research on all aspects of the biology of Crustacea and other marine arthropods.
