Pathology Basics Quiz

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.
