The endocrine system is a network of chemical communication among cells in vertebrate animals. The classical vertebrate endocrine system consists of a group of discrete glands that secrete unique products (hormones) into the bloodstream. These products travel in the blood to distant sites or targets, where they cause specific physiological Author: Nancy Barnes Clark. Michael R. Kanost, in Encyclopedia of Insects (Second Edition), Hemolymph is the circulating fluid or “blood” of insects. It moves through the open circulatory system, directly bathing the organs and tissues. Insect hemolymph differs substantially from vertebrate blood, with the absence of erythrocytes and a high concentration of free amino acids being two of the common. The glands of vertebrates are derived from _____ epithelium. exocrine If the connection between the gland and the epithelial membrane is maintained as a duct, the gland is called a(n) ___________ gland.

Lymph nodules and Lymph glands. Lymph glands, haemolymph glands, and the spleen have a similar origin m the embryo. at first small dense areas of mesenchyma developing near blood and lyn^)hatic vessels. The blood vessels extend into these areas producing a notch on one side of the mass, known as the hilus. ADVERTISEMENTS: In this article we will discuss about the endocrine glands in vertebrates with the help of a suitable diagram. Elasmobranchii: Elasmobranchs have most of the vertebrate endocrine glands. They are thyroid pituitary, adrenal tissue, pancreas, mucous membrane of stomach and duodenum, and gonads. There are no thymus and parathyroids as such. Vertebrates are more complex organisms when compared to invertebrates. The primary difference between the two is that vertebrates possess a backbone and an internal skeleton. In some vertebrates, the bones are replaced with cartilage, as seen in sharks. Another defining characteristic of vertebrates is that they reproduce sexually. The book also points out that the group lumps a vast number of species together, so that no one characteristic describes all invertebrates. In addition, some species included are only remotely related to one another, with some more related to vertebrates than (unranked): Filozoa.
