Endocrine system Endocrinology is the study of chemical communication systems that provide the means to control a huge number of physiologic processes. Like other communication networks‚ endocrine systems contain transmitters‚ signals and receivers that are called‚ respectively‚ hormone producing cells‚ hormones and receptors. The first step in understanding endocrinology is to explore the meaning of such terms as hormone‚ receptor and target cell‚ and to obtain an understanding of how chemical

Explain the mechanism of communication‚ control‚ and integration in the endocrine system. The Endocrine systems mechanism of communication is sending messages from the cells of the endocrine and nervous system to the cells in other systems by releasing hormones. The Endocrine systems control feature is part of negative feedback because it

Introduction: The endocrine system is the second greatest control system of the body and has many effects on the tissues and organs. The thyroid gland‚ which is a part of the endocrine system‚ releases a hormone that maintains metabolism. This hormone is thyroxine. Thyroxine production is controlled by thyroid stimulating hormone‚ which is released by the pituitary gland. TSH stimulates the thyroid gland to produce thyroxine. In this experiment‚ the effects of TSH and thyoxine on metabolic rate

EXERCISE 27 Functional Anatomy of the Endocrine Glands Gross Anatomy and Basic Function of the Endocrine Glands 1. Both the endocrine and nervous systems are major regulating systems of the body; however‚ the nervous system has been compared to an airmail delivery system and the endocrine system to the pony express. Briefly explain this comparison. The nervous system is a lot more fast acting and more rapid action occurs when compaired to the endocrine and the slow path through the blood stream

RESEARCH 1. Give the importance of the endocrine system ~ The endocrine system helps regulate and maintain various body functions by synthesizing (making) and releasing hormones‚ chemical messengers. The major areas of control and integration include responses to stress and injury‚ growth and development‚ absorption of nutrients‚ energy metabolism‚ water and electrolyte balance‚ reproduction‚ birth‚ and lactation. The endocrine system is composed of glands that release their hormones directly into

to release hormones in your body. The definition for endocrinology is defined in many different ways‚ but with all related meanings that sum up to the physiology of the endocrine glands. The endocrine system sends messages to the endocrine glands in your body that include the adrenal‚ pituitary‚ thyroid‚ and parathyroid glands‚ as well as‚ the hypothalamus‚ pancreas‚ ovaries‚ and testes. There are two main systems in the body that control the proper functioning of the body. The nervous system

Chapter 45 Hormones and the Endocrine System Lecture Outline Overview: The Body’s Long-Distance Regulators An animal hormone is a chemical signal that is secreted into the circulatory system that communicates regulatory messages within the body. A hormone may reach all parts of the body‚ but only specific target cells respond to specific hormones. A given hormone traveling in the bloodstream elicits specific responses from its target cells‚ while other cell types ignore that particular
