Document Summary

Endocrine system i (sections 40. 1, 40. 2, and 45. 1) I. outcomes: compare/contrast different cell signaling types and types of hormones in animals (go crazy! Muscle: organs- different tissues organized into functional activity, organ system- organs that work together, whole organism -> emergent property. D. coordination and control (important: figure 40. 6: all tissues, organs, and organ systems must work together, 2 major systems coordinate responses to stimuli, endocrine system- hormones, nervous system. C. mechanisms of homeostasis (important: figure 40. 8: stimulus- fluctuation in variable above or below set point, sensor- detects stimulus, response- physical activity. D. feedback control (two types: negative feedback- response reduces stimulus to help restore pre-existing state, restores to set point, most common in animals, positive feedback- response amplifies stimulus, not major in animals, examples: orgasms and breast feeding. A. chemical messengers secreted in body fluids: chemical signaling molecule responsible for regulation, messenger of endocrine system. C. binds to target cells: all cells exposed but only those with receptors respond.
