Study Notes
Definition of Pathology
- Study of disease, its nature, causes, development, and consequences.
- Focuses on the structural and functional changes in cells, tissues, and organs.
Branches of Pathology
-
Anatomical Pathology
- Examines tissue specimens (biopsies, surgical specimens).
- Involves histopathology (microscopic examination) and autopsy pathology.
-
Clinical Pathology
- Involves laboratory analysis of bodily fluids (blood, urine).
- Includes hematology, microbiology, immunology, and clinical chemistry.
-
Molecular Pathology
- Studies diseases at the molecular and genetic level.
- Utilizes techniques like PCR and next-generation sequencing.
Key Concepts
- Etiology: Study of disease causes (genetic, infectious, environmental).
- Pathogenesis: Mechanisms by which diseases develop and progress.
- Morphological Changes: Structural alterations in cells and tissues due to disease.
- Clinical Manifestations: Signs and symptoms presented by a disease.
Types of Diseases
- Infectious Diseases: Caused by pathogens (bacteria, viruses, fungi).
- Autoimmune Diseases: Immune system attacks the body's own tissues.
- Neoplastic Diseases: Abnormal growth of cells (benign and malignant tumors).
- Degenerative Diseases: Progressive loss of function or structure (e.g., Alzheimer's disease).
Diagnostic Techniques
- Biopsy: Removal of tissue for examination.
- Cytology: Study of individual cells.
- Imaging: Techniques like X-rays, CT scans, MRIs to visualize internal structures.
- Laboratory Tests: Blood tests, cultures, and other assays to identify diseases.
Importance of Pathology
- Provides a basis for diagnosis and treatment decisions.
- Helps in understanding disease mechanisms and developing new therapies.
- Essential for research in medical science and improving patient care.

-
Anatomical Pathology:
- Analyzes tissue specimens, including biopsies and surgical samples.
- Involves histopathology (microscopic examination) and autopsy pathology.
-
Clinical Pathology:
- Conducts laboratory analyses of bodily fluids like blood and urine.
- Encompasses hematology, microbiology, immunology, and clinical chemistry.
-
Molecular Pathology:
- Investigates diseases at molecular and genetic levels.
- Utilizes advanced techniques such as PCR and next-generation sequencing.
Key Concepts
- Etiology: Examines causes of diseases, including genetic, infectious, and environmental factors.
- Pathogenesis: Studies mechanisms underlying disease development and progression.
- Morphological Changes: Identifies structural alterations in cells and tissues caused by disease.
- Clinical Manifestations: Reviews signs and symptoms associated with specific diseases.
Types of Diseases
- Infectious Diseases: Result from pathogens, including bacteria, viruses, and fungi.
- Autoimmune Diseases: Occur when the immune system erroneously attacks the body’s own tissues.
- Neoplastic Diseases: Characterized by abnormal cell growth, encompassing benign and malignant tumors.
- Degenerative Diseases: Defined by a progressive loss of function or structure, exemplified by conditions like Alzheimer's disease.
Diagnostic Techniques
- Biopsy: Involves tissue removal for further examination to identify diseases.
- Cytology: Focuses on the study of individual cells to detect abnormalities.
- Imaging: Utilizes methods like X-rays, CT scans, and MRIs to visualize internal structures.
- Laboratory Tests: Includes blood tests, cultures, and assays to accurately identify diseases.
Importance of Pathology
- Serves as a foundation for accurate diagnosis and treatment planning.
- Enhances understanding of disease mechanisms, aiding in the development of new therapies.
- Plays a crucial role in medical research and improving overall patient care.
