endocrine system in invertebrates slideshare

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. 2. 17. It is divided into an anterior lobe, intermediate zone, and posterior lobe, all of which are involved in either hormone production or hormone secretion. The arthropods are the largest and most advanced group of invertebrate animals, rivaling and often exceeding the evolutionary success of the vertebrates. pituitary gland. flatworms. The best understood endocrine systems are those of insects, followed by crustaceans, echinoderms and mollusks, although the latter are perhaps characterized by the most diverse hormonal systems of the invertebrate phyla. 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. These glands may be specialized for the production of . kc. 5. The endocrine system of the rest of the vertebrates is poorly studied.
