All Rights Reserved 1.5 Feedback Loops Are a Key Mechanism Used to Maintain Homeostasis (1 of 8) Feedback Loops—A change in a regulated variable causes effects that feed back and in turn affect that same variable •Made up of a series of events that lead to an output •As the loops continue, this output then influences the events of the loops themselves •Negative Feedback Loops—Oppose the initial change and reduce the output •Positive Feedback Loops—Reinforce the initial change and increase the output Copyright © 2025, 2019, 2016 Pearson Education, Inc. All Rights Reserved 1.5 Feedback Loops Are a Key Mechanism Used to Maintain Homeostasis (2 of 8) Negative Feedback Loops—Promote stability; Negating any stimulus that moves a variable away from homeostasis •Each variable has a Set Point that includes a Normal Range around that set point •The range differs for individual variables Copyright © 2025, 2019, 2016 Pearson Education, Inc. All Rights Reserved 1.5 Feedback Loops Are a Key Mechanism Used to Maintain Homeostasis (3 of 8) Steps of a Negative Feedback Loop 1.Stimulus—Information that a regulated variable is outside the normal range 2.Receptor or Sensor—Cellular structure that registers the stimulus 3.Control Center—Stimulus is sent to the control center (brain or gland) by the nervous or endocrine systems 4.Effector—The cells or organ that will react 5.Responses—Effector causes the response that will return the variable to the normal range Copyright © 2025, 2019, 2016 Pearson Education, Inc.

All Rights Reserved 1.5 Common Misconceptions about Homeostasis (1 of 2) •Misconception 1: Negative feedback is bad for the body; Positive feedback is good –Under normal circumstances, both types of feedback loops promote homeostasis •Misconception 2: Maintaining homeostasis means the body’s internal environment is static or unchanging –Maintenance of normal ranges does not mean the internal environment is unchanging; Changes are normal and are occurring constantly Copyright © 2025, 2019, 2016 Pearson Education, Inc. All Rights Reserved 1.5 Common Misconceptions about Homeostasis (2 of 2) •Misconception 3: Regulatory mechanisms and feedback loops are either “on” or “off,” like a switch –The internal environment is dynamic so feedback loops always exhibit some degree of activity •Misconception 4: Any physiological variable can be controlled –Variables can only be controlled through feedback loops if receptors exist to detect changes in the set point Copyright © 2025, 2019, 2016 Pearson Education, Inc.

All Rights Reserved 1.5 Childbirth, Pitocin, and Positive Feedback Loops •Childbirth begins when a woman goes into labor, which occurs by a positive feedback loop •Baby’s head stretches the cervix (stimulus); Data from nerves in the cervix (receptors) are sent to the brain (control center); Uterus (effector) produces hormone oxytocin which stimulates uterine contractions (response); This continues and is amplified until the baby is born, which stops the feedback loop •Pitocin is a synthetic version of oxytocin that is used when labor needs to be artificially started, or induced Copyright © 2025, 2019, 2016 Pearson Education, Inc.
