Study Notes
Feedback Mechanisms in Physiology
- Negative Feedback Control: Involves mechanisms that correct deviations from a set point to maintain homeostasis.
- Positive Feedback Mechanism: Increases or amplifies the initial stimulus, often leading to intensified processes; typically associated with injury or disease rather than homeostasis.
- Homeostasis: The maintenance of a stable internal environment within the body, essential for proper functioning.
- Set Point: The normal or average value for a variable; adjustments can occur due to physiological demands, such as temperature changes.
Anatomy and Physiology
- Importance: Understanding how the body responds to internal and external environments.
- Anatomy: Investigates the structural organization of the body, including relationships between different components.
- Systemic Physiology: Focuses on the functions of body systems and how they interact.
- Cellular Physiology: Examines the processes occurring within cells, including signaling and metabolism.
Anatomical Terminology
- Anatomical Position: Defined as a person standing erect, facing forward with palms facing forward; serves as the standard reference for body orientation and relationship.
- Relational Descriptions: Based on the anatomical position, used consistently regardless of how the body is oriented.
Feedback Mechanism Components
- Receptor: Detects changes or deviations from the set point.
- Control Center: Processes information and determines the appropriate response.
- Effector: Carries out the response to restore balance.
Other Key Concepts
- Environmental Responses: Physiological adjustments are made in response to environmental changes.
- Body Temperature Adjustments: Temporary changes to set points can occur during activities, illustrating flexibility in homeostasis.
- Deviation Correction: A negative feedback response identifies deviations from the set point and corrects them, aiming to achieve a normal range.
