Q Module 1Critical Thinking Assignment Homeostatic Mechanism Homeostasis is the ability of an organism to maintain a relatively constant internal environment with fluctuations occurring around an ideal set point. Homeostasis works much like a thermostat with changes in a variable such as temperature being detected by a receptor. A control center receives the information, assesses how far from the set point a change may be, and initiates a response to return the system back toward the set point. The effector brings about that change. Homeostasis is a very important concept in physiology because all cells, tissues, organs and organ systems are designed to maintain homeostasis for optimal health and functioning. The usual mechanism for returning systems to homeostasis is negative feedback, but there are some examples of positive feedback that serve important functions in the body. • Begin your paper by explaining what negative feedback is and how it works to maintain homeostasis. Compare this mechanism to positive feedback. • Using blood glucose control as an example, explain how negative feedback works to keep blood glucose levels relatively constant. Contract this to positive feedback, using labor and childbirth as your example. • What is the stimulus, receptor, control center and effector for each of these examples? • Discuss another example of a homeostatic system in the human body that is regulated by negative feedback. Requirements: • Your paper should be 2-3 pages in length, excluding title and reference pages. • Include at least two scholarly references, in addition to the course textbook. Also cite your sources in the body of the paper. The following link to the CSU Global Writing Center provides more information on how to find scholarly sources. • Conform to the APA guidelines in the CSU Global Writing Center. • The CSU Global Library is a good place to find these references.
