Study Notes
Function and Mechanism in Physiology
- Function aspect explored by physiologists asks "what" questions, focusing on the purpose or role of a physiological system or process.
- Mechanism aspect explored by physiologists asks "how" questions, focusing on the underlying processes and mechanisms that explain the functioning of a physiological system or process.
Homeostasis and Control Systems
- Homeostasis aims to maintain a stable internal environment, despite changes in the external environment.
- In control systems, regulated variables are kept within a narrow range or setpoint.
- Negative feedback loops stabilize the variable around the setpoint, counteracting changes that move the variable away from the setpoint.
- Positive feedback loops amplify the originating stimulus, leading to a rapid change in the variable.
Key Concepts
- The primary focus of Mechanism is to understand the underlying processes and mechanisms that explain the functioning of a physiological system or process.
- The primary focus of Function is to understand the purpose or role of a physiological system or process.
- Homeostasis is essential for maintaining a stable internal environment, which is crucial for the proper functioning of physiological systems.
