Question 40

Complete each statement by inserting your answers in the answer blanks. (1) There are three essential components of all homeostatic control mechanisms: control center, receptor, and effector. The (1) senses changes in the environment and responds by sending information, input, to the (2) along the (3) pathway. The (4) analyzes the input, determines the appropriate response, and activates the (5) by sending information along the (6) pathway. When the response causes the initial stimulus to decline, the homeostatic mechanism is referred to as a (7) feedback mechanism. When the response enhances the initial stimulus, the mechanism is called a (8) feedback mechanism. (9) feedback mechanisms are much more common in the body.
