Positive Feedback Mechanism MDCAT Quiz; Positive feedback mechanisms are specialized processes by which the response to a stimulus amplifies the effect initially produced, moving the system to a specific objective. This topic holds great importance for MDCAT aspirants seeking to score highly in physiology and endocrinology. You will be able to understand these mechanisms and their biological importance by developing a deep understanding of them through an MDCAT Quiz.
Understanding Positive Feedback Mechanisms
Positive feedback differs from negative feedback in that it increases the output of a process. For example, during delivery, oxytocin secretion makes uterine contractions more intense. This, in turn, causes the release of more oxytocin until the birth of the baby. Similarly, blood clotting occurs through a cascade that amplifies the process in order to result in a stable clot. In this way, these mechanisms hold great importance in specific physiological functions, and studying them in depth will help you get better at answering detailed questions for MDCAT.
