Which Of The Following Is Not An Endocrine Gland

Endocrine system, any system found in animals that produces hormones, substances that regulate how the body functions. This type of system can be, in its simplest form, the neurosecretory, which includes one or more centers of the nervous system, up to the number of glands found in the human endocrine system.

Thyroiditis: Types, Causes, Symptoms, Diagnosis & Treatment

Comparative biologists study the evolution of the endocrine system and the role of the system in animal interactions with the environment and reproduction. Studies in mammals have provided information with extensive endocrinology studies in mammals, including humans. For example, the effects of the pituitary hormone prolactin on serum and salt control were first discovered in fish, and the same mechanism was later demonstrated in animals. The role of local sperm synthesis (paracrine action) in oocyte (egg) development was discovered in the star and later in the uterus. The importance of thyroid hormones in embryonic development was first demonstrated in tadpoles in the early 1900s. Furthermore, the isolation and characterization of many mammalian hormones has been achieved largely using other vertebrates such as bioassay systems; that is, early animals were simple and easy to measure the amount of hormone produced by the mammary gland. Finally, some invertebrates and animals provide “model systems” for research that have provided valuable information on the nature of hormone function and the mechanism of hormone production. For example, one of the most studied systems to sense the effects of hormones on target organs is the progesterone and estrogen receptors (hormones secreted by the gonads) in the oviducts of chickens.

Understanding how the endocrine system is regulated by non-predators also provides important information for managing wild or captive populations. Controlling the reproductive composition of salmon is of great importance to the salmon industry as a whole. Attempts to reduce insect species based on pheromone knowledge. Understanding rare species helps them breed better in captivity and thus prevent extinction. Future research may also lead to the recovery of some endangered species.

The primary endocrine system appears to be the neurosecretory type, where the nervous system either secretes neurohormones (hormones that are activated or released by the nervous system) into the bloodstream or stored in tissues. their end). interact with blood vessels, allowing neurohormones to be released into the bloodstream), where they are released in large quantities when needed. True endocrine glands may have developed as separate hormone-secreting organs later in the evolutionary history of the animal kingdom. Some of the cells in the endocrine glands are derived from nerve cells that go to different parts of the body during evolution. These independent endocrine glands have only been described in arthropods (where neurohormones are also a type of endocrine messenger) and insects (where they are developed).

It has become clear that many hormones previously attributed to sperm are secreted only by non-living animals (for example, the pancreatic hormone insulin). Similarly, many non-living enzymes have been discovered in the tissues of animals, including humans. Some of these molecules are produced by single-celled animals and plants and act as chemical regulators similar to hormones in higher animals. Thus, the history of endocrinological management has ancient beginnings, and the most important evolutionary changes seem to be the use of tools.

Vertebrates (phylum Vertebrata) are divided into at least seven different phyla that represent evolutionary groups of animals with similar characteristics. Class Agnatha, or jawless fish, is the earliest group. The class Chondrichthyes and the class Osteichthyes are brown fishes that originated millions of years ago from Agnatha. Chondrichthyes include cartilaginous fish such as sharks and rays, while Osteichthyes are bony fish. Bony fish known as goldfish, salmon and perch are advanced members of teleosts, teleosts, the first to develop lungs and fall. From the teleosts comes the class Amphibia, which includes frogs and pearls. Amphibians rose to the order of Reptilia, adapted well to land and diverged along many lines of evolution. Among the groups derived from ancient creatures are turtles, dinosaurs, alligators, crocodiles, snakes and snakes. Birds (class Aves) and mammals (class Mammalia) then come from separate groups of reptiles. Amphibians, reptiles, birds, and mammals are collectively called tetrapods (four-legged).

The human endocrine system is the result of millions of years of evolution. and it should not surprise us that the endocrine glands of man and their associated hormones have some connection with the endocrine systems of early vertebrates. By studying these animals, it is possible to write a clear record of the hypothalamus-pituitary system, as well as many other endocrine glands during the evolution of fish, which preceded the existence of terrestrial animals. The endocrine system is made up of cells, tissues. . and organs that secrete hormones as a primary or secondary function. The endocrine system plays a major role in this system. The main function of the sebaceous glands is to secrete their hormones into the surrounding fluid. The central fluid and blood vessels then carry the hormones throughout the body. The endocrine system includes the pituitary gland, the thyroid gland, the parathyroid gland, the adrenal gland and the pineal gland (Fig. Some of these glands have endocrine and endocrine functions. For example, the pancreas contains cells that make the pancreas and cells that secrete the hormones insulin and glucagon, which regulate blood glucose levels. The hypothalamus, thymus, heart, kidneys, stomach, small intestine, liver, skin, testicles in women, and testes in men are other organs that have cells that have endocrine functions. Adipose tissue has long been known to secrete hormones, and recent studies have shown that it is the bone tissue that has endocrine functions.

The endocrine glands are not to be confused with the body’s exocrine system, glands that release their secretions through ducts. Examples of exocrine glands are sebaceous and sweat glands. As we have already seen, the pancreas also has an exocrine function: many of its cells secrete pancreatic juice through the ducts and organs into the small intestine. The endocrine system produces hormones that control and regulate many bodily functions. The endocrine system coordinates with the nervous system to control the functions of other body systems. Endocrine cells secrete molecular signals called hormones. Endocrine cells can form endocrine glands, they can be cells, or they can be located in organs or tissues that have functions other than making hormones. Hormones circulate throughout the body and cause reactions in cells that have receptors that can bind to them. Mutations in the cells affect the function of the human body in which they are located. Many hormones are released in response to signals from the nervous system, so both systems work together to change the body.

Maintaining homeostasis in the body requires the coordination of many different systems and organs. One form of communication between neighboring cells and between cells and tissues in distant parts of the body is the release of chemicals called hormones. Hormones are released into body fluids, usually blood, that carry them to the affected area. The cells that secrete hormones are found in specialized organs called endocrine glands and consist of cells, tissues, and organs that secrete hormones. Most of them are the circulatory system. Examples of endocrine organs include the pancreas, which produces the hormones insulin and glucagon to lower blood glucose levels, the adrenal gland, which produces hormones such as epinephrine and norepinephrine that regulate stress responses, and the thyroid gland, which produces thyroid hormones. metabolic rate.

Endocrine glands are different from exocrine glands. Exocrine glands secrete chemicals through ducts that exit the gland (not into the bloodstream). For example, our sweat glands are secreted into sweat ducts on the surface of the skin. The pancreas has endocrine and exocrine functions, in addition to secreting hormones
