tailieunhanh - Lecture Mosby's paramedic textbook (4th ed) - Chapter 26: Endocrinology

This chapter include objectives: Identify the purpose of the patient care report; describe the uses of the patient care report; outline the components of an accurate, thorough patient care report; describe the elements of a properly written emergency medical services (EMS) document; describe an effective system for documenting the narrative section of a prehospital patient care report;. | 9/10/2012 1 Chapter 26 Endocrinology 2 Lesson 26. 1 Endocrine Glands and Hormones 3 Copyright © 2013 by Jones & Bartlett Learning, LLC, an Ascend Learning Company 1 9/10/2012 Learning Objectives • Describe how hormones secreted from the endocrine glands help body maintain homeostasis. • Describe anatomy and physiology of pancreas and how its hormones maintain normal glucose metabolism. 4 Endocrine System Anatomy and Physiology • Composed of ductless glands and tissues that produce and secrete hormones – – – – – – – Major endocrine glands Pituitary Thyroid Parathyroid glands Adrenal cortex and medulla Pancreatic islets Ovaries and testes • Other specialized groups of cells that secrete hormones are found in kidneys and mucosa of GI tract 5 6 Copyright © 2013 by Jones & Bartlett Learning, LLC, an Ascend Learning Company 2 9/10/2012 Endocrine Gland Functions • Secrete hormones directly into bloodstream and regulate various metabolic functions • Products of endocrine glands travel via blood (or tissue fluids) – Able to exert effects at widespread sites, often distant from source of origin 7 Endocrine Gland Functions • Endocrine hormones are released – In response to change in cellular environment – To maintain normal level (. homeostasis) of hormones, other substances – To simulate or inhibit organ functions 8 Endocrine Gland Functions • This integrated chemical and coordination system enables – Reproduction – Growth and development – Regulation of energy • Target organs and body tissues have hormone receptors and are able to respond to a particular hormone 9 Copyright © 2013 by Jones & Bartlett Learning, LLC, an Ascend Learning Company 3 9/10/2012 How are hormones and their target organs like a lock and key? 10 Hormone Receptors • Hormone categories – Proteins – Polypeptides – Derivatives of amino acids – Lipids • .
