They synthesize and secrete steroid molting hormones (ecdysteroids) and their activity is controlled by external and internal signals. T he X-organ/sinus gland (XO/SG) complex located in each eyestalk represents a major neuroendocrine structure in decapod crustaceans (for review see Fingerman 1992).Several physiological processes are controlled by neurohormones from the eyestalks. In crustaceans, the X-organ-sinus gland (XO-SG) neurosecretory system is formed of distinct populations of neurons that produce two families of neuropeptides: crustacean hyperglycemic hormone and adipokinetic hormone/red pigment-concentrating hormone. Immunoperoxidase in X-organ serial sections showed co-localization of GABA and glutamic acid decarboxylase (GAD) including the aforementioned neurons.

The sinus glands of each of the crustaceans so far examined (Callinectes, Carcinus, Libinia, Pagurus, Uca, Crago, and Palaemonetes) have been easily isolated from the re-maining stalk tissue. Crustacea is a large (~67,000 known species) and diverse Subphylum of arthropods [], populating various niches ranging from terrestrial to marine, from flourishing tidal zones to extremely harsh and low populated environments such as thermal vents.Due to their extremely wide dispersal they serve as model organisms to monitor toxicity [] and environmental changes [], while on the other hand . 2001 Mar;24(3):146-54 Papers are published in English only, but abstracts or summaries in French, German, Portuguese, or Spanish may be added when appropriate. -, J Exp Biol.

This unique selection of reviews summarizes current knowledge in all major fields of crustacean neurobiology and all levels of their CNS organization, using lobster and crayfish. In crabs and lobsters, the sinus gland (a neurohemal organ that contains the nerve endings of the X-organs) acts as a storage and release site for neuropeptides, which are synthesized in peripheral neurons in the eyestalk [20].

Academic Press, New York, pp 473-536. Endocrine control of molting in decapod crustaceans involves the eyestalk neurosecretory center (X-organ/sinus gland complex), regenerating limbs, and a pair of Y-organs (YOs), as molting is induced by eyestalk ablation or multiple leg autotomy and suspended in early premolt by limb bud autotomy. The sinus glands (SG) were dissected under the microscope while covered with ice-cold crustacean saline6 and kept in a small volume of ice-cold water (1~1 per SG). 1995 Dec;112(4):573-9 has enabled us to extend these observations, and show more clearly the influence of this gland on growth inhibition.
