Derives its name from the fact that various glands release hormones directly into the blood, which in turn transports the hormones to target tissues via ducts. METABOLISM METAMORPHOSIS Primarily regulates other endocrine glands, rarely a factor in endocrinological emergencies.

General Characteristics Endocrine glands and their hormones help to Regulate metabolic processes, Play a vital role in reproduction, growth, and development, Control the rates of certain chemical reactions, Aid in the transport of substances across membranes . Estrogen and androgen receptors occur in a number of marine and freshwater prosobranchs
The prosobranch mollusks and the echinoderms use at least partially or even totally comparable hormones as vertebrates so that vertebrate-type sex steroids are produced in these groups and play a functional role. most hormones are stored, often in large quantities, in, ENDOCRINOLOGY - . 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). Most of the similarities among the endocrine systems of crustaceans, arthropods, and vertebrates are examples of convergent evolution. Historically, invertebrates have been excellent models for studying endocrine systems and for testing toxic chemicals.
