Study Notes
Cellular Adjustments
- Cells continuously adjust to changes in the extracellular environment to maintain homeostasis.
- Adaptations allow cells to function optimally amid varying physiological conditions.
Study of Sufferings
- The study of sufferings is known as "pathology," focusing on the nature and causes of diseases.
Cellular Stress Responses
- Excess physiologic or pathologic stress can lead to cellular injury, potentially resulting in cell death.
Aim of Cellular Adaptations
- The primary aim of cellular adaptations is to enable cells to survive and function despite stressors and challenging conditions.
Dynamic Stability
- The ability of a cell to maintain a dynamically stable state is referred to as "homeostasis."
Functionality of Cells
- The specific function of each cell is dependent on its differentiation and the microenvironment in which it operates.
Consequences of Irreversible Injury
- Irreversible injury leads to cell death, characterized by necrosis or apoptosis.
Example of Pathologic Hypertrophy
- An example of pathologic hypertrophy includes the enlargement of cardiac muscle due to high blood pressure (hypertension).
Main Cause of Hypertrophy
- The main cause of hypertrophy is increased workload or demand on the cells, triggering growth responses.
Types of Adaptations
- Two types of cellular adaptations include hypertrophy (increase in cell size) and hyperplasia (increase in cell number).
Reversibility of Injury
- The factor determining the reversibility of injury is the severity and duration of the stressor impacting the cell.
Adaptation in Pathology
- Adaptation in pathology refers to the cellular and organismal changes in response to stress that allow survival despite adverse conditions.
Focus of Adaptation in Pathology
- The focus is on understanding how cells adapt to stress and the consequences of those adaptations, whether beneficial or harmful.
Causes of Cellular Injury
- Cellular injury can be caused by various factors including lack of oxygen, toxic substances, infections, and immune reactions.
Biological System Adjustments
- Biological systems can make continuous short-term adjustments through processes like feedback mechanisms and compensatory responses to maintain balance.
