Study Notes
Overview of Pathology
- Definition: The study of the nature, causes, and effects of diseases.
- Focus: Understanding disease mechanisms at cellular, tissue, and organ levels.
Major Branches of Pathology
-
Anatomical Pathology
- Includes tissue examination (histopathology) and autopsies.
- Uses microscopy to identify disease changes in tissues.
-
Clinical Pathology
- Involves laboratory analysis of blood, urine, and other bodily fluids.
- Focuses on diagnosing diseases through tests.
-
Molecular Pathology
- Examines diseases at the molecular level.
- Incorporates techniques like DNA/RNA analysis.
Disease Mechanisms
-
Etiology
- The study of disease causation (e.g., infectious agents, genetic factors, environmental influences).
-
Pathogenesis
- The development and progression of disease.
- Involves understanding cellular and molecular changes.
Common Pathological Processes
-
Inflammation
- Body’s response to injury/infection.
- Can be acute or chronic.
-
Necrosis
- Uncontrolled cell death due to factors like infection or ischemia.
-
Apoptosis
- Programmed cell death, vital for normal development and health.
-
Fibrosis
- Excessive connective tissue formation in response to injury.
Types of Pathological Conditions
-
Infectious Diseases
- Caused by pathogens (bacteria, viruses, fungi, parasites).
-
Neoplastic Diseases
- Characterized by abnormal cell growth (benign or malignant tumors).
-
Autoimmune Diseases
- Immune system attacks healthy cells (e.g., lupus, rheumatoid arthritis).
-
Metabolic Disorders
- Abnormal metabolism, including diabetes and thyroid disorders.
Diagnostic Tools in Pathology
-
Biopsy
- Removal of tissue for examination.
-
Cytology
- Study of individual cells, often used in cancer diagnosis.
-
Immunohistochemistry
- Uses antibodies to detect specific antigens in cells/tissues.
-
Genetic Testing
- Analyzes DNA for mutations linked to diseases.
Importance of Pathology
- Provides vital information for diagnosis and treatment planning.
- Essential for research and understanding disease mechanisms.
- Plays a role in public health by monitoring disease outbreaks.

Pathological Processes
- Necrosis: Uncontrolled cell death, often caused by injury or disease.
Common Pathological Conditions
- Necrosis, inflammation, and cancer.
Immunohistochemistry
- Immunohistochemistry: Used to identify specific proteins and other molecules in tissues, helping diagnose diseases and understand their mechanisms.
Disease Development and Progression
- Pathogenesis: Describes the development and progression of a disease.
Cellular Diagnostic Tools
- Cytology: The study of individual cells, often used for cancer diagnosis.
Autoimmune Diseases
- Lupus: An autoimmune disease where the body's immune system attacks its own tissues.
Fibrosis
- Fibrosis: Typically indicates the formation of scar tissue, often in response to injury or chronic inflammation.
Molecular Pathology
- Molecular Pathology: Focuses on the molecular basis of disease, including gene mutations, protein changes, and cellular signaling pathways.
Benefits of Understanding Pathology
- Diagnosis: Helps to identify and diagnose diseases.
- Prognosis: Allows for the prediction of disease course and potential outcomes.
- Treatment: Guides the development of effective treatment strategies.
Structure of Chromosomes
- Linear chromosomes: Considered the primary form of DNA in most organisms
Components of Chromosomes
- Centromere: The structure responsible for organizing and stabilizing the DNA within the chromosome.
Function of Chromosomes
- Chromosomes: Carry genetic information and play a crucial role in cell division, ensuring that each daughter cell receives a complete copy of the genome.
Chromosomal Genes
- Genes: Found on chromosomes and are responsible for inheritable characteristics.
Modification of Chromosomes During Apoptose
- Fragmentation: Chromosomes undergo fragmentation during apoptosis, a controlled form of cell death.
