The hormonal regulation of biological functions is a common characteristic for all animal phyla, including invertebrates. 1 A structure which makes hormones in the body is called endocrine glands. Some invertebrate endocrine systems are well suited for testing chemicals and environmental media because of the ease of using certain species, their sensitivity to toxic chemicals, and the broad choice of models from . The molting of an insect to becoming an adult is regulated by three important hormones.

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. The Human Endocrine System www.slideshare.net. The adrenal medulla releases adrenalin (epinephrine) and norepinephrine in times of stress.Identical to the effects of the sympathetic nervous system, but longer lasting.Accelerated heartbeat, increased blood pressure, higher levels of blood sugar and increased blood flow to heart and lungs.The adrenal cortex produces the steroid hormone cortisol (hydrocortisone).Reduces inflammation.Synthetic derivatives such as prednisone are used as anti-inflammatory agents.Stimulates carbohydrate metabolism.s, The pancreas is a composite gland consisting of exocrine andendocrine portions (figure 15.11a).
