Characteristics of a good question: The purpose for asking the question is clear and accurate. Question clearly and accurately identifies the issue/problem Question is testable, contains variables Engage You will be viewing some video clips from Sideshow: Alive On The Inside. Within these clips you will see various types of endocrine disorders. Write down observations and questions you have about the endocrine system.

Endocrine System Structures Glands – release products to bloodstream directly. Horomones – products deliver messages to body Target cells – have specific receptors for specific hormones Endocrine Glands Section 39-1 Hypothalamus The hypothalamus makes hormones that control the pituitary gland. In addition, it makes hormones that are stored in the pituitary gland. Pituitary gland The pituitary gland produces hormones that regulate many of the other endocrine glands. Parathyroid glands These four glands release parathyroid hormone, which regulate the level of calcium in the blood. Thymus During childhood, the thymus releases thymosin, which stimulates Tcell development. Adrenal glands The adrenal glands release epinephrine and nonepinephrine, which help the body deal with stress. Pineal gland The pineal gland releases melatonin, which is involved in rhythmic activities, such as daily sleep-wake cycles. Thyroid The thyroid produces thyroxine, which regulates metabolism. Pancreas The pancreas produces insulin and glucagon, which regulate the level of glucose in the blood. Ovary The ovaries produce estrogen and progesterone. Estrogen is required for the development of secondary sex characteristics and for the development of eggs. Progesterone prepares the uterus for a fertilized egg. Testis The testes produce testosterone, which is responsible for sperm production and the development of male secondary sex characteristics Hypothalamus Controls pituitary secretions Links nervous system to endocrine Pituitary Glands Controls the other endocrine glands aka Master Gland Hormone Functions Growth Regulates growth of organism Hormone (GH) Antidiuretic Stimulates kidneys to keep (ADH) water Thyroid Glands Regulates balance metabolism and energy Hormone Function Thyroxine Regulates body energy usage Regulates calcium and phosphate in blood Calcitonin Parathyroid Glands Regulates calcium levels Hormone Function Parathyroid Hormones (PTH) Increases calcium, phosphate and magnesium absorption in intestines Causes bones to release calcium and phosphate Adrenal Glands Releases hormones to deal with stress Secretes adrenaline Hormone Function Corticosteriods Controls blood pressure and blood sugar levels Triggers fight or flight response Epinephrine/ norepinephrine Pancreas Glands Regulates blood sugar levels Secretes insulin Hormone Function Insulin Lowers blood sugar by packaging glucose molecules in glycogen to be stored in the liver Raises blood sugar by breaking down glycogen in glucose Glucagon Pancreas Feedback Loop 1. After a meal blood sugar levels are high 2. Triggers release of insulin 3. Formation of glycogen molecules 4. Stored in liver thereby lowering glucose in blood 5. Before a meal blood sugar levels are low 6. Triggers release of glucagon 7. Glycogen molecules are broken down into glucose molecules Thymus Glands Secretes Thymosine Part of the immune system Hormone Function Thymosine T-cell development Before meals Target tissues need glucose Glucose levels are low in the blood Glucose sent to target tissues Pancreas secretes glucagon Liver changes glycogen to glucose After a meal Target tissues don’t need glucose Glucose levels are high in the blood Glycogen sent to target tissues Pancreas secretes insulin Glucose goes to the liver and glycogen is produced Diabetes Diabetes High sugar levels in blood Do not produce enough insulin to control blood sugar Some take insulin injections to regulate Reproductive Glands Production of gametes Secretion of sex hormones Sex Gland Hormone Gamete (sex cell) Ovum Female Ovaries Estrogen Male Testosterone Sperm Testes Explain Section 39-2 The Endocrine System regulates Metabolism Calcium and glucose levels Response to stress by means of the by means of the by means of the by means of the Testes Thyroid Growth Water balance Reproduction by means of the by means of the Pituitary Ovaries Pancreas Parathyroids Adrenals Aim: to describe functions of the endocrine system; to identify malfunctions in the endocrine system Homework: 1 min quiz KIPP STAR Science Rental Agreement Do Now: Endocrine System Quiz Classwork: Diabetes Case Study When Things Go Wrong With the Endocrine System October 5, 2012 Pituitary Hypothalamus Thyroid Thymus Adrenal Pancreas Ovaries Testes When Things Go Wrong With the Endocrine System! Directions: Read and summarize using the Rule-base strategy. Write a paragraph explaining which endocrine system disorder you would find easiest to live with. Just a paragraph! So dig deep and delete! Remember to use A.C.E. I.T! Explain List 4 types of endocrine glands and give their function. What is the overall function of the endocrine system? With what other systems does the endocrine system interact?
