4 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. anatomy of the endocrine system hormones hormone secretion control Functions and Control of the Endocrine System

5 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. endocrine glands –hormones –secrete directly into bloodstream exocrine glands –secrete through a duct Anatomy of the Endocrine System

6 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. steroid hormones–lipid-based amino acid hormones–protein-based hormone receptors –upregulated–increased –downregulated–decreased Hormones

7 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. neural control –epinephrine hormonal control –hypothalamic-releasing hormone humoral control –glucagon Hormone Secretion Control

8 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. Hormone Secretion Control

9 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. negative feedback –mechanism that reverses a condition that has exceeded the normal homeostatic range to restore homeostasis Hormones and Homeostasis

10 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. helps regulates body temperature The Hypothalamus

11 Permission granted to reproduce for educational use only.© Goodheart-Willcox Co., Inc. True or False? 1. Endocrine glands secrete hormones. 2. Endocrine glands have ducts. 3. Steroid hormones are proteins. 4. Hormone receptors can only be upregulated. 5. Glucagon is under humoral control. Review and Assessment
