The pituitary gland is called as the master gland of the endocrine system in higher mammals. Advances in the study of invertebrate endocrine systems have lagged behind those in vertebrate endocrinology, largely due to the problems associated with adapting investigative techniques that are appropriate for large vertebrate animals to small invertebrates. MIH appears to prevent the release of ecdysone from the Y-organs. The pituitary gland has two lobes: the anterior and posterior lobes. ing. Click here to review the details.

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. The pituitary gland is a small endocrine organ that controls a multitude of important functions in the body. Role of Ecdysone Embryonic ecdysteroids may mediate the formation of the various embryonic envelopes that surround the embryo during development And/or They may be involved in early morphogenesis as described for insects Ecdysteroids may also play a gonadotropic role in crustaceans, 13.

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. An endocrine system consists of those glandular cells, tissues, and organs whose products (hormones) supplement the rapid, short-term coordinating functions of the nervous system. The androgenic gland hormone is an insulin-like neuropeptide. In males, it causes the testes to produce a hormone that regulates sperm production.Adrenocorticotropic hormone (ACTH) stimulates the adrenal gland to produce steroid hormones.
