Endocrine Disruptors Certain compounds are likely to act as endocrine disruptors not only by a direct binding to receptorsacting as hormone-mimics (agonists) or as antihormones (antagonists)but also indirectly by modulating endogenous hormone levels by interfering with biochemical processes associated with the production, availability, or metabolism of hormones or also by the modulation of receptors. 3. The structure of JH has been determined to be a methyl ester with the empirical formula C18H30O3. The endocrine system is a chemical messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into the circulatory system, regulating distant target organs. As You know: Invertebrates are animals without a backbone. They are distinct from the other type of gland, endocrine, in that exocrine gland secretions end up external to the body, while endocrine secretions go into the bloodstream/internal. Abstract.

ENDOCRINE SYSTEM. The results of studies on the distribution of neurosecretory neurons and ordinary epithelial endocrine cells imply that the neurohormones were the first hormonal regulators in animals. Growth in Crustaceans Occurs through molting = ecdysis
Stages of molting
Proecdysis - preparation for molting
epidermal cells separate from the old cuticle (apolysis) and divide forming the new exoskeleton
Calcium removed from old exoskeleton
hepatopancreas - release of energy reserves from storage (animal stops feeding)
Ecdysis
shedding of the old exoskeleton
cuticle is soft - rapid uptake of water
Metecdysis
Mineral deposition into the new cuticle
Endocuticle formation
Feeding begins again
New tissue formation follows
Increased DNA and protein synthesis
tissue replaces water
Intermolt
As skeleton and tissue growth nears completion metabolism is shifted to storage of energy reserves into the hepatopancreas
Regulation of many processes is involved
Metabolism
Water /mineral balance
Molting process. Endocrine Disruptors Our ignorance of invertebrate endocrinology is one of the main reasons for the unsatisfactory progress that has been made regarding endocrine disruptors (ED) in invertebrates.
