The endocrine system affects a large number of the body’s functions, including temperature, metabolism, sexual function, reproduction, moods, and growth and development. Yes! Diseases of the endocrine system can result from the oversecretion or undersecretion of hormones … The pituitary gland, or hypophysis, is an endocrine gland about the size of a pea. Start studying Endocrine System - Glands, Hormones, and Function. Start studying Endocrine Glands, Hormones, and their functions and structure. These glands produce hormones. If hormonal production is interrupted, natural or synthetic versions of these hormones can be administered pharmacologically to restore and maintain normal endocrine function. The endocrine system is a series of glands that produce and secrete hormones that the body uses for a wide range of functions. d) most hormones travel a long distance and act on target cells, they are called circulating (or endocrine) hormones; while other hormones Learn about how to keep your body in balance. The pituitary gland, sometimes called the master gland, in turn controls the functions of many other endocrine glands.The pituitary controls the rate at which it secretes hormones through a feedback loop in which the blood levels of other endocrine hormones signal the pituitary to slow down or speed up. Hormones of Thyroid Thyroid gland basically releases two hormones Triiodothyronine (T3) and Thyroxine (T4), which helps in controlling the metabolism of our body. ... endocrine glands release their products into the general. e.g. Each lobe is about 5 cm long, 3 cm wide and 2 cm thick. This is one of the important hormones that the adrenal gland produces. These hormones stimulate other endocrine glands for secretion. The pineal gland is a small, pine-cone shaped endocrine gland in the brain. Recent work has revealed that there are two types of neurosecretory cells: type A which stain with para-aldehyde fuchsin, … Target organ. All of the body’s functions can be influenced in some way or the other by the endocrine system and this includes metabolism, growth, water and electrolyte balance, sexual function, reproduction and even behavior. • Rising levels of thyroid hormone feed back to inhibit the anterior pituitary and hypothalamus. Endocrine Glands. The hormones cause certain reactions to occur in specific tissues. Exocrine glands, by comparison, secrete substances inside and outside of the body using ducts.These two methods of transport mark the difference between exocrine and endocrine glands. Apart from specialized endocrine glands for this purpose, there are other organs such as the kidney , liver , heart and gonads , which has a secondary endocrine function. They do not have any ducts which connect them to the surface of the body. Health tools for patients and caregivers, provided by the Endocrine Society. List the general functions of hormones.
